What music file format is recommended? Part 2

AUDIO FORMATS

Opus is a new audio compression format developed by the IETF and standardized by RFC6716 in 2012. There is very little hardware and software supported, but at low bit rates of 128 kbps or less, it appears to be the strongest sound quality with compression with lost.

audio formats

Vorbis is a free audio file format developed by Xiph.org. It seems to be used on Youtube too. Since the standard bit rate is 112 kbps, the sound quality at a low bit rate appears to be good.

WMA is a standard Windows audio compression method developed by Microsoft. If the bit rate is 160 kbps or less, it exceeds the MP3 upper limit frequency. However, the size will be a little larger.

AAL (ATRAC Advanced Lossless) is a lossless compressed version of ATRAC mentioned above. According to Sony, it can be compressed to about half the size of the data without losing any music information on the CD, but it actually seems to vary considerably depending on the sound source.

As the name implies, Apple Lossless (ALAC) is Apple’s lossless compression audio codec. Used in iTunes, etc.

FLAC is an audio file format developed and distributed as free open source software. It seems to be the most popular in lossless compression.

Monkey’s Audio is an audio format that compresses PCM losslessly without degrading sound quality. It is so named because it is used in music playing software called Monkey’s Audio. The characteristic is that it does not fit the name and the compression rate is high.

TAK is a high-speed, high-compression, lossless compression audio encoder. It has the same level of compression as Monkey’s Audio, but it’s pretty crazy.

TTA is a free real-time lossless compression audio encoder / decoder. Like TAK, it’s too manic so I wouldn’t use it.

WMA Lossless is a lossless compressed version of WMA mentioned above.

Equalizer Image
AIFF is an uncompressed audio file format developed by Apple. It seems to be the Windows WAV. It seems to have been used on Macintosh (Mac) for a long time.

WAV (WAVE) is a format for describing audio data developed by Microsoft and IBM. This is what happens when you convert a CD (Linear PCM) into an uncompressed file in Windows.

Also, the sound quality of lossy compressed music file formats is almost the same at 192 kbps bit rates. If it is 160 kbps or less, I am wondering if other compression formats are slightly better than MP3. In this case, it is better to check the music player software. Sound quality is exactly the same for lossless and uncompressed music file formats. Lossless compression will have issues with compression ratio and playback load.

I want to read it together
What is free high-quality music player software for Windows?
After all, what music file format is recommended?
Image of listening to music with a portable music player
I’ve mentioned it so far, but I recommend MP3 or WAV (AIFF). The reason is as follows.

Due to the large capacity of hard drives and flash memory, lossy compressed music file formats do not need to have a bit rate lower than 192 kbps.
The compression ratio of the lossless music file format is currently 60 to 70% maximum, so taking into account the encoding time and effort and loading during playback, the file format of Uncompressed music is sufficient for lossless compression.
I don’t think I can distinguish between 192kbps MP3 and WAV, so I can’t help but worry about the compression format.
MP3 and WAV have many compatible hardware and software.

What music file format is recommended?

audio format

There are many types of music file formats, so it is difficult to know which one is recommended.

AUDIO FORMAT

I have only used MP3 and WAV due to their confusion, so I don’t really know about the new music file formats that are increasing year after year. So, I took a quick look at the existing music file formats based on the information from the internet. Let’s make a list of types and extensions so that you can easily understand them later.

* The target is a music file format that can be converted from a CD (linear PCM).


* The format can be replaced with the term codec and the extension can be replaced with the term file format. Simply put, a codec is a device or software that can encode (encode) and decode (decode) data in both directions using one encoding method. A file format is an information device like a computer. It is the storage format of the file used in.

* The bit rate for lossy compression is 192 kbps.

* The corresponding items indicate the amount of hardware and software that the music file format supports. ◎ Many, ○ Many, ▲ Normal, △ Less, × Very few.

Currently, lossless compression is emerging as a compression format in addition to lossy compression. Irreversible compression (lossy compression) is a data compression method in which the data before compression and the data after compression do not completely match, and reversible compression (lossless compression) is the data before and after compression. It is a data compression method that exactly matches the data.

In other words, lossy compression is a poor sound quality compression method because it adds a reduction in the amount of data, and lossless compression is a good sound quality compression method because it does not reduce the amount of data. . They are all the same in the sense that they aim for high sound quality with the smallest possible size.

Now, I’m sure there are music file formats that you already know, but let’s briefly explain each one.

Mixer Image
AAC is a music file format standardized in 1997 (approved in 1999). Standardized in order to obtain high sound quality and high compression that exceeds MP3. If the bit rate is 160 kbps or less, it exceeds the MP3 upper limit frequency.

ATRAC is a voice data compression technology developed by Sony since 1992. If the bit rate is less than 128 kbps, it is above the upper frequency limit of MP3.

HE-AAC is a music file format standardized in 2003. By incorporating SBR technology into the aforementioned AAC, the playback band has been expanded and the sound quality and compression efficiency at low bit rates (128 kbps or less) have been vastly improved.

* SBR (Spectral Band Replication) is a technology for audio compression and encoding, which aims to strengthen the conventional encoding method and increase the compression rate.

MP3 is the oldest music file format standardized in 1991 (approved in 1993). Since it is old, it has a high penetration rate and there is a large amount of supported hardware and software.

There are many types of voice file formats, as well as image file formats.

Audio Files

Since the digital audio files are easy to copy, the illegal copy and distribution of music files has become a problem these days.

As explained in what analog data is, the mechanism of digital audio files is that analog signals become digital data and are saved.

Explaining in detail the conversion method, to convert an analogue to digital waveform, it is necessary to perform a job called “sampling” that measures (record) the sound waveform at regular intervals, and is the sampling cycle. The sampling frequency is called (sampling frequency).

The sampling frequency represents the number of samples per second and is in Hz. In other words, it is a unit that expresses how many times the sound is measured and recorded per second, and the greater the value, the more faithful the original and greater sound becomes the quality of the sound. However, the amount of data will increase proportionally.

The sampling frequency of a typical music CD is 44.1 k Hz. However, even if the sampling frequency is increased, there are sounds and frequency bands that can not really be recorded, so some classical music enthusiasts love expensive analogue equipment.

In addition, it is not only the sampling frequency, which affects the quality of the sound, but also the “sampling bit” that indicates the strength (volume) of the sound (16 bits are 65,535, 24 bits are 16,777,215). (Express) and “Number of channels” (number of sound lines recorded as stereo, monaural and 5.1 channels) also have an effect. The higher the value, the greater the sound quality.

Another factor that greatly affects sound quality is the bit rate. The bit rate represents the amount of data to be recorded per second and the unit is “BPS”.

In other words, the higher the bit rate, the more information can be stored, which results in a higher sound quality. As will be described in detail below, in the MP3 file format, 128 K BPS is the minimum bit rate that can be heard.

However, there is “constant bit rate” and “variable bit rate” in the bit rate. The constant bit rate is the same bit rate that is fixed from the beginning to the end of the voice, and the variable bit rate increases or decreases the bit rate according to the amount of voice information.

In other words, the bit rate is high for clauses with multiple voices and the bit rate is low for simple low voice clauses. You can reduce the total size of the file by choosing a variable bit rate.

This is the information contained in the digitized data of analog audio signals.

However, digitized data can not be used as. Just converting this data into an arbitrary file format and saving them, it will be possible to use them with multimedia devices and application software that admit that format.

The storage format of said data

file format

Is named. A file format is a file format with an extension.

Then, to save the data in a file format, it is necessary to transform (encode: encoding) the data according to that format. (For coding, see What is a character code?)

A dedicated program is used to codify the data, but said coding program is

Codec (codec)
Is named. In other words, the gross data obtained by converting analog signals into digital data are processed by a codec to market them as a file format.

Therefore, there are many types of codecs and coding methods for each type of codec.

Most current codecs are programs that compress and encode data when creating a file and decompress (decompress) data by playing a file. In general terms, codecs are used to compress and decompress data. It refers to a compression method program of this type.

Audio File Formats

Apart from M4A, there are many other active audio formats. For example, the popular MP3, AC3, WMA, OGG, etc.

Audio Formats

 

What is the difference between M4A and MP3, AC3, WMA? What is better about M4A than MP3, AC3, WMA and OGG? Then read the next sentence to see the battle in audio compression format.

M4A and MP3: Both M4A (MPEG 4 audio) and MP3 (MPEG3 audio) are audio compression formats developed by the Motion Picture Experts Group (MPEG). Next, I will introduce the differences between M4A MP3 in terms of file size, sound quality and compatibility.

Sound Quality: The M4A format, known as Apple Lossless Encoder, aims to replace MP3 with a new standard for audio compression. However, when comparing M4A MP3 for sound quality, M4A is better. Generally speaking, it is recommended to store music with M4A audio at 192 kbps bit rate for good sound quality and small file size.

File size: In terms of file size, M4A is often believed to have superior sound quality than MP3 when encoded at the same bit rate. For example, with 128-bit AAC (M4A), a 4 minute song would be 3.8 MB. To maintain the same sound quality with MP3, it is necessary to encode at a rate of approximately 192 bits. Then the file size will exceed 3.8MB.

Compatibility: Currently, M4A is only used on PC, iPod and other Apple devices and is not as popular as MP3. In contrast, all computers, music players, and mobile phones can play MP3 files.

Tip: If sound quality is a priority, neither M4A nor MP4 is the best option. It is advisable to choose the uncompressed WAV format. However, the size of the WAV file is about 10 times that of M4A and MP3. Therefore, WAV, which takes up too much space when creating a music collection, is not the best format.

M4A, MP3 and WMA: WMA A lossy compression codec developed by Microsoft. Like other new formats, M4A and WMA have higher compression efficiency and better sound quality than MP3. Sound quality is particularly good at low bit rates. As a result, WMA works well for low-bandwidth video streaming. Therefore, songs purchased from online music stores Napster, Musixmatch, and Wal-Mart must be stored in WMA. However, WMA cannot be played on Apple iPod, which is a shame.

Audio Files Formats

CD discs

audio file formats

The audio CD format, or rather the .cda extension, appeared around the same time.

Unlike “wave” files saved on the hard disk, they cannot be edited. Today it can be opened in an audio processing program, reformatted by audio transcoding, and saved anywhere other than on a CD.

After specifying the output format and the device we will play them on, the conversion will begin. For all these tasks, we only need to drag and drop the elements that we are working with in its user interface. For example, if we are playing a file at twice the speed, an easy way to interpolate would be to play one sample out of two.

If you place the object at 50% pitch, you should double the number of samples, and an easy way to do this is to find the average of the two actual samples. Well, this signal needs to be decompressed, and this requires a proportionally higher CPU load that can “saturate”. And a less saturated processor means less risk of “hang.” We will analyze the most popular compression formats that will allow us to compress any file without losing information. What is fast? The most powerful?

MP3 codec
With the advent of the LAME MP3 Encoder codec, the music industry experienced a real shock, because those files “weighed” dozens of times less than the same WAV file. Even a five minute compose at full compression rarely exceeds the size of 5-7MB. Agree, a significant advance, not to mention the fact, allowed not only to adjust the above characteristics, but also some additional parameters in the form of ID3 tags, which contained information, for example, about the artist, album name and tracks. , the release date.

What is file compression? What does squeeze mean?
And the most used? Have you ever come across a file that was too busy and you didn’t know how to make it work less, like mail it to a friend? Compressing the file allows us to reduce the size of the file. It will take up less space on your hard drive and it will be easier to send. Depending on the type of file used and the type of compression, its size will be reduced more or less.

What compression formats are there and which are the most popular?
As we just said, there are several types of compression methods. For example, it is a compression method used to compress video, audio, or image files. The main characteristic of this compression method is that by compressing approximations, the media file is reduced in size. This method looks for repeating patterns in addition to other more advanced methods. This is achieved by reducing the file size without loss of information or quality, although obviously the file size is not reduced. Unlike the previous case, this information is not lost. … When it comes to compression formats and methods, we have a wide range.

This type has become the most popular. Look, almost the entire Internet is full of this universal format. In general, we can say that the MP3 audio format has become a true revolution in sound. It remains one of the most popular and in-demand so far, even though it is being replaced by other types of audio. But more on that later.

Introduction
As always, I’ll start with the senile complaints. Twenty years ago … In fact, twenty years ago there was no particular option. Because there were CDs that were turned into WAV files that took up the space of an average “hard drive”, well, there was quite a bit of space left in the operating system. And on the BBS. And the games. And in the archive of files. And that’s it. Because the average size of a hard drive back then was a whopping 850 megabytes today. Yes, exactly that 850, and exactly one megabyte. The impetus for everything was given by the appearance of the MP3 format in 1997, and it was a very significant year!

The first audio format in computer games

Audio Format

The first mention of computer sound came from the creation of primitive games at the time, in which sound was played through the system’s speaker. But no matter how hard the developers of such software (software) have been, the required quality, compatible with tape or reel recordings or recorders, could not be achieved.

High definition digital music has been around for a long time. Why does it seem that it is now catching on? In addition to traction, they can have devices like one, the answer on the market. The author of this disappearance does not have to look very far. Except in special cases, most of the users are more than enough for their smartphone to listen to music. Even players that have settled down, you see, they reduce the ground they hit year after year.

That is why many manufacturers are looking for a solution on how to change the audio format so that the sound is natural. Frankly, this has led to more competition than we have now. This applies not only to the material being played, but also to studio sound, live performances, quality or basic parameter settings in terms of knowledge of physics, acoustics, etc.

We come to the millionth question. This requires a sensitive ear and some education. If you’re a high-profile foodie, you’ll probably know the difference first, but for ordinary mortals who only listen to music with a background meter, it’s probably too hard to pay the difference just to have that kind of quality.

It is not just a music player. Those that combine with this equipment are not cheap. To top it all, there is music that is sold in high definition formats, which is also a bit more expensive. Finally, this is the technical section. There is not even consensus among audio professionals themselves on whether these devices make such an important distinction. At least on paper, it seems that HD music sounds better, but there is a strong marketing component behind it. Are we willing to pay to see the audience as music lovers?

The appearance of the WAV format
It is believed that the first full quality of audio formats was associated with the appearance of the standard and the .wav file extension (this abbreviation was formed from the English word “wave” or wave). Anyway, he became the first-born that could be processed into computer programs on a professional level.

As is usual in most multimedia files with which we work almost daily, we link to video with photos or audio files, depending on the type of use that we are going to make of them, we must use them in a specific format, so It is also important to know the main differences between them.

But this is what we are going to talk about, these are some alternatives that we are going to present to you and that will be very helpful when it comes to testing and converting the different types of audio files that we usually find. If you want to know the main differences between the two, we recommend that you take a look at this post that we offer you.

DTSaudio formats

DTS – Digital Theater System, in fact, is Dolby Digital, or rather its competitor. DTS uses a lower compression rate than Dolby, so it actually sounds better, as evidenced by DVDs that have DTS or DD tracks. DTS in home theater systems uses a maximum bit rate of 1536 kbps (full bit rate), this sound is better than Dolby Digital’s AC-3 format. DTS – Uses 6 free audio tracks and supports 7.1 sound distribution system, with this DTS 4.0 bit rate – it will sound as immersive as Dolby 5.1.

AIFF VS FLAC

FLAC

FLAC – (Free Lossless Audio Codec). Unlike lossy codecs (MP3, Ogg, and AAC), it does not remove any information from the audio stream and is designed for listening to music on high-quality Hi-Fi and Hi-End equipment and for archiving a professional audio collection. Currently, the FLAC format is supported by many audio players and music applications. The basic decoder uses ID3v1 and ID3v2 tags to store basic types of metadata, so they can be freely added and edited.

MIDI

MIDI: (Musical Instrument Digital Interface), unlike other formats, MIDI does not store digital sound, but sets of commands: notes played, links to instruments, sound parameters. The convenience of the MIDI format is to use a device that is arranged according to the indicated chords. Midi files are typically several orders of magnitude smaller than digitized audio of the same quality. The MIDI format is versatile and designed so that any sequencer can read and write data without loss. At the same time, MIDI information that is incomprehensible to other software applications does not lead to misunderstandings, but is simply ignored. The mid-year backing track format allows you to save information about the instrument used, the tempo, the size designation, the information about the musical keys, the name of the track and the patterns and their number.

MP3

MP3: (MPEG Layer version 3) At the moment, MP3 is the most popular digital music encoding format. MP3 is a lossy compression format, that is, part of the audio information, according to the psychoacoustic model, the human ear can barely perceive is removed from the original file, irrevocably. The debate on MP3 quality still continues … First, the quality of the resulting MP3 depends not only on the bit rate of the compressed file, but also on the version of the encoding program used: the codec. Many music gourmets prefer to compress music with “maximum quality” – 320 kbps, or switch to other formats, for example FLAC, where the average bit rate is ~ 1000 kbps. At the moment, MP3 is the leader in universal recognition, but at the same time it is not a professional format in terms of technique. Professional musicians and DJs no longer use tracks with a bit rate lower than 320 kbps.

MODIFICATION

MOD is a format designed for the Amiga platform. Each MOD file contains digitized recordings of actual instrument sounds, called samples, somewhat similar to the structure of MIDI. Cj or a composer who writes in the MOD format uses a program called a tracker, in which he specifies what instrument, at what time, what note and octave should sound; This sequence of notes is written in a list; one track and several tracks. sounding in parallel forms a block called a pattern. The pattern collection forms a module: a file in MOD format, with the extension .mod. A track bar corresponds to an actual channel in which cj can play or edit numbered notes. Notes can be assigned various “patterns”, for example: tremolo, glissando, and so on.

OGG

OGG – Vorbis was developed in 2002 by the Xiphophorus team as an alternative to all paid licensed audio formats. Ogg Vorbis is compatible with all popular platforms. The format does not restrict the user to just two channels of audio (left and right), it supports up to 255 separate channels at a sample rate of up to 192 kHz and up to 32 bits, making Vorbis ideal for encoding DVD-Audio of 6 channels. home theater audio.

Many different computing methods have emerged. Audio data storage – digital: OGG, Mp3, Flac, Wav formats.
It is impossible to consider and discuss all audio formats, codecs, their advantages and disadvantages, so in our article we will try to talk about the most popular audio file extensions that you may have to work with.
Why can’t we use any universal audio file encoding format?

Because for the implementation of various functions, a different format is required. For example: to play CDs in a CD-ROM drive, to record music or sound effects in video games, to record a movie track or video clip, to play on mobile phones or transfer files over the Internet, in addition, there are a number of of operating systems that are the most used in the world. These include: Amiga, Macintosh, NEXT, and Windows personal computers. Also, the job of a dj, sound engineer, cj, video engineer, or a simple music lover is quite different in nature. This may require that your audio data be saved in your own way. For example, the audio on a CD must be saved using 16 bits and a sampling frequency of 44.1 kHz. However, to download sound over the Internet, it is better to use a different bit depth and sample rate, as each minute of 16-bit, 44-kilohertz audio takes about 10MB. those. an average 5 minute track will be 50 “meters” – this is too much information for the average user. This article presents brief information on the most popular music formats.

AA (audible audiobook file)

AA (Audible Audio Book File) is a proprietary format developed by Audible. It is used to record audiobooks that are sold through the Audible and iTunes services. It is possible to reduce or accelerate the speed of listening to files: digital tone, the ability to leave bookmarks when listening to audiobooks, file protection, when delivering sound recordings over the Internet.

AAC (advanced audio coding)

AAC (Advanced Audio Coding) is an audio file format with less loss of quality when encoding than MP3 in the same sizes. Lossless music encoding of original quality using the ALAC profile. AAC is a family of MPEG4 audio coding algorithms. Unlike the hybrid mp3 filter bank, AAC uses MDST (Modified Cosine Transform) technology, which means that the listener gets better sound quality than MP3 encoding with the same or lower bit rate. Possible AAC file extensions: .m4a. m4b .m4p.

AIFF

AIFF – This is the audio data format for the Apple Macintosh platform. The .aiff format supports 8- and 16-bit mono and stereo. If files in this format contain a Mac-Binary header (text, photos, copyright holder information, a single number, etc.), then the file will have the extension .snd. You can listen to an audio file with the extension .nd using Sound Forge. Forge will, of course, open such a file, but it will recognize it as a Macintosh resource format and it will not affect sound quality.

APE (mono audio)

APE – (Monkey’s Audio), developed by Matthew T. Ashland is a lossless digital audio format. Monkey’s audio codec is released for Microsoft Windows platform only, although there are several unofficial codecs for MacOS, Linux, BeOS Monkey’s audio files use the following extensions: .ape to store audio and .apl to store metadata This format is not free as its license severely restricts the distribution of .ape files.

Audio File Format

There are many different audio formats.

audio file formats

You can’t even imagine how many audio formats there are. Now we will consider only the most popular ones, and if you need complete information, you can find it on Wikipedia.

Audio formats
Sound is itself an analog phenomenon. In order for it to register on a computer, it must be digitized. Digitized audio takes up a lot of space. Therefore, they use special algorithms to encode and compress data: codecs. Codecs provide encoding / decoding of audio / video data, as well as compression / decompression of such data. Download a set of codecs for Windows:

The type of media file format (audio or video, no difference) is determined by its extension. For example, MP3 files have the extension .mp3. The codec for this format is always the same: MPEG Layer-Ç. But for the MP4 format, the codecs may be different.

Some formats, such as MP4 and FLV, can contain streaming audio and video. So, if you see a file with the extension .mp4, you can’t definitely tell that it contains only music or only video, or a movie – audio and video. After all, initially in such formats, the possibility of transmitting both audio and video was raised.

We all know that once information is compressed, it can be lost. Therefore, all codecs can be divided into two groups: with loss of quality and without loss of quality. Don’t be intimidated by the word “lossy”: As a general rule, codecs cut off “unnecessary” information that is invisible to our eyes and ears (almost invisible).

Lossless compression codecs include:

FLAC (Free Lossless Audio Codec);
APE (Monkey’s Audio);
ALAC (Apple Lossless Audio Codec).
And here are the lossy codecs:

If you are a fan of sound then it makes sense to look for music in FLAG format. For normal home listening, the most popular MP3 format is sufficient. Also, to experience the total difference between MP3 and FLAC formats, you need professional sound reproduction equipment; unfortunately, the tablet does not belong to said team. So I don’t see any reason to download FLAC music to a tablet.

Now let’s take a quick look at the audio formats themselves:

WAV is the first (or one of the first) audio formats. It is used to store uncompressed audio recordings. One minute of recording in WAV format requires 10MB. An audio CD is usually copied in this format and then the resulting WAV files are compressed with an MP3 codec to save space.
MP3 (MPEG Layer-3) is the most widely used audio format. It reduces the sound with a loss of quality, but only the sound that is not heard by the human ear is cut off. As a result, a person does not hear the difference and the sound takes up less space. The main characteristic of this format is the bit rate. The higher the bit rate, the better the sound quality. Uncompressed audio CD has a bit rate of 1411.2 Kbps. The highest sound quality in the case of MP3 format is achieved at a bit rate of 320 Kbps. Anything below 320 Kbps is of worse quality . The difference between 128 Kbps and 320 Kbps is already felt by ear, so if you can download recordings with a higher bit rate, go for it.
WMA (Windows Media Audio) is a format developed by Microsoft for the Windows operating system. Microsoft tried to create a replacement for MP3, but, as time has shown, it failed.
OGG is an open format that supports encoding of audio with various codecs. The most widely used OGG codec is Vorbis. In terms of compression quality, the format is comparable to MP3, but less common in terms of media player and audio player support. If you can download music in MP3 and OGG format, you should choose MP3 because your audio player may not support OGG format.
AAC is a proprietary audio format that provides better sound quality than MP3. It is currently the best lossy audio coding algorithm. A file of this format can have the extensions aac, mp4, m4a, m4b, t4p, t4g.
FLAC is a lossless compression format. It does not make any changes to the audio stream, so the sound encoded with it is identical to the original. Used for listening to sound in high-level sound systems.
Video formats
There are no fewer video content formats and standards than audio formats. Let’s start with the international standards that define the data storage and encoding format of multimedia files:

Today, everyone seems to be aiming to become filmmakers. People use a wide variety of gadgets and devices for filming, including mobile phones and digital cameras, as well as portable and professional video cameras. The latest generation of digital SLR cameras can record high definition video, which is being replaced by Ultra HD (4K) video.

It takes effort to learn how to make good videos, but it becomes even more difficult when you want to show your video masterpiece in all its glory to friends, family, or put it online for everyone to see. You may need to upload it to YouTube, you may want to burn your own Blu-ray Disc or DVD, or you may just want to upload a video to your mobile phone or tablet.

Everything you need to know about video codecs and containers

Let’s first understand the types of codecs. General concept of codecs

If you chat with people who are into video processing or visit the relevant web forums, one way or another, you will find yourself involved in the sometimes heated debate about which codec is better. In fact, the effectiveness of any codec is highly dependent on the compression mode used and the type of video material being processed. So it is worth considering different codecs, taking into account their specific use and the characteristics of the compressed material. Video codecs are mainly covered below, but the section on format containers also mentions the use of audio codecs. Video recording and archiving

Most modern consumer electronic devices receive content in some kind of already compressed format. As a general rule, only professional video operators work with uncompressed HD video. Of course, ideally, if possible, in the presence of a large-capacity storage system, the video files should be stored in the original recording format, because this ensures the highest quality. Transcoding a video from one type of compression to another can introduce subtle artifacts that can degrade image quality. (These errors are minimized with good software transcoding.)

Today, many codecs with specific specializations are offered. The average user may never find most of them. The next section is dedicated to codecs, such as compression / decompression systems, used as part of special software that is designed to encode or transcode video files.

x.264 / MPEG-4 AVC (Advanced Video Coding). This most common codec is used in modern digital video and still cameras, in which shooting results are saved as files on built-in hard drives, memory cards, etc.

H.265 (HEVC – High Efficiency Video Coding) the latest most efficient video compression standard developed in response to the need to migrate to ultra high definition video, known as Ultra HD or 4K.
H.265 was originally developed as HEVC (High Efficiency Video Coding). It was approved as the official successor to H.264 in April 2013.

MJPEG (Motion JPEG). This is an older format used by some older generation digital cameras and video equipment. It was developed by experts who participated in the development of the JPEG (Joint Picture Experts Group) codec to compress ordinary still images, hence the name of this codec.

DV and HDV The DV standard was developed by a consortium of video technology companies for tape storage systems and was often used in camcorders with a mini tape cassette slot. Some DV versions have been used successfully in professional camcorders, and the HDV version has been developed to support high definition tape cassettes.
