Video file formats / formats Part 3

Incidentally, the existence of some half-finished frame rates is due to technical restrictions in the transition of television transmission from black and white to color.

In fact, for applications other than broadcasting, 30 fps and 60 fps are often used.

On some platforms, the upper limit of the frame rate of the videos that can be sent can be set to 30 fps, but higher frame rates are still progressing, such as the video recording function of smartphones and YouTube that supports 60 fps. Super Hi-Vision, which is being developed as a next-generation streaming standard, has an even higher value of 120 fps.

1-5. Field order (drawing method)
There are two main types of video drawing methods, “progressive” and “interlaced”.

The drawing method is often expressed as a set with the vertical size of the resolution or the frame rate (or the number of fields). For example, 1280 x 720 progressive is “720p”, 1920 x 1080 interlaced is “1080i”, 24fps progressive is expressed as “24p”, 60-field interlaced is expressed as “60i”, and so on.

The video is made up of a collection of many points, and the points are divided into a block of horizontal lines (this is called a scan line) and displayed according to the drawing method. There is a difference in how this scan line is displayed between progressive and interlaced.

Field order
Currently, most of the media like YouTube recommend the progressive format, so it is good to remember that you basically use the progressive format for WEB videos.

Therefore, in progressive, the scan line of an image is twice as large as that of interlaced, so that the moving image becomes clearer. In interlaced, the moving image is less sharp, but the moving image is smoother with less data. .Can be displayed in.

1-6. Bit rate
Bit rate is a unit that is also used in communication lines, etc., but in video, it is a value that indicates how many bits per second are used to represent video data and audio data, and the rate value of bits is ◯ bps., ◯ b / s, or ◯ bit / s.

If the bit rate value is large, the amount of data packed per second will be large, so the video and audio quality will naturally improve. On the other hand, if the bit rate value is small, the video and audio quality will be reduced, but the video capacity will be reduced.

The higher the resolution of the video, the more noticeable the detailed drawing will be, so higher resolution videos will require a higher bit rate.

Also, there are two main types of bit rates: constant bit rate (CBR) and variable bit rate (VBR). Constant bit rate (CBR) refers to a compression method with a constant bit rate and variable bit rate (VBR) refers to a compression method with a variable bit rate.

Since CBR always has a constant bit rate, it has the advantage that it is easy to predict the size of the video in advance, and it has the disadvantage of using many bit rates. On the other hand, VBR adjusts the bit rate according to the scene, so it can improve the image quality by file size, but it has the disadvantage that the file size cannot be predicted. Variable Bit Rate (VBR) is recommended for YouTube.

Also, in the VBR (file compression / encoding) encoding method, “1-pass encoding” is used to encode the content of the file without parsing, and an appropriate bit rate is assigned after analyzing the data before encoding. . There is something called “2 -pass encoding” for encoding. With 2-pass encoding, analysis is done in advance, so encoding takes more time, but can produce high-quality video.

Bit rate

2. Recommended format for each platform
With that in mind, let’s take a look at an overview of the recommended formats for each video platform.
* See official help for the latest and most detailed information.

2-1. Youtube
YouTube supports a wide range of file formats, but the help page has recommended encoding settings, so it’s a good idea to check that out.

2-2. Facebook / Instagram
Facebook also supports a wide range of file formats. AAC of 1080p or less is recommended for video and 128 kbps or more for MP4 audio. Consider the aspect ratio, such as screen occupancy.

Video file formats / formats Part 2

Video file formats / formats Part 2

Files that are handled on a personal computer have an extension so you can see what kind of data they are.

For notepad it is “.txt”, for Excel it is “.xls” or “.xlsx” and for images it is “.jpg” or “.png”.

Video files have the same extensions, such as “.mp4”, “.mov”, “.avi” and “.mpg”.

For example, there are more than 10 types of video keys (= codecs) that correspond to the extension “.mov”. In other words, the extension in the video is just a guide to predict the content and keys.

Although it can be identified that it is a video file by looking at those extensions, the extension and the video file, and the video file and the key (= codec) are not one by one, so the extension is just a guide. . to show your identity Always makes it difficult to handle video files.

The main video files, extensions and codecs are summarized below. If you only know the extension and want to check the codec, you should use a software called codec checker like “MediaInfo” or “Vacuum Wave Lab SuperLite”.

Most of the major video players these days, like Windows Media Player for Windows and QuickTime Player for Mac, have a built-in key (= codec), and most of them can play videos with that software. However, keep in mind that some of them are not supported. You need to get that codec or get a player that includes that codec.

Video file format explanation Main extensions Main codecs
MP4 has a high compression rate and is very convenient, but it is difficult to determine the content because there are many codecs. The recommended format for YouTube is H264 mp4 format. .mp4 .m4v (Video) MPEG1 MPEG2 MPEG4 H.263 H.264 H.265 H.264 / AVC WMP9 (Audio) AAC-LC AC-3 MP3 HE-AAC VQ Apple Lossless
MOV A standard file for working with videos on Mac. It is based on MP4 and can also use the MPEG-4 video codec. .mov .qt (Video) MPEG-4 H.264 Motion JPEG (Audio) AAC MP3
MPEG-2 PS It is used as the recording format for DVD and the like. A standard based on the assumption that bit errors are small, created on the premise of storage media. .mpg .mpeg .mpe .m2p (Video) MPEG-1 MPEG-2 (Audio) MPEG1 Layer-II MPEG2 Layer-II LPCM AC-3
MPEG-2 TS The format used by many digital transmission standards around the world. Used in HDTV and Blu-ray recorders .mpg .mpeg .mp2 .m2p .m2t .mpt .m2ts .mts .ts .vob (Video) MPEG1 MPEG2 MPEG4 H.264 / AVC (Audio) MPEG1 Layer- II MPEG2 Layer-II MPEG4 AAC-LC LPCM AC-3 MP3
AVI Please note that the old format cannot be played if the file is incomplete and there are restrictions such as a maximum capacity limit of 2GB. There are a lot of codecs here too. .avi .divx (Video) MPEG1 MPEG2 MPEG4 Motion JPEG DivX 3-5 XviD (Audio) MPEG1 Layer-III MPEG2 Layer-III PCM AC-3
1-4. Frame rate
The frame rate is a value that indicates how many image frames (frames) are recorded per second, just like character reading, and the frame rate value is ◯ fps or ◯ f / s. I will describe it. In other words, if 30 images (frames) are recorded per second, the value will be 30 fps or 30 f / s.

The higher the frame rate value, the smoother the video will move, and the lower the frame rate value, the more choppy the video will be. In other words, the frame rate can be reformulated as a value that represents the smoothness of the moving image display.

The video on the right reproduces the difference in video depending on the frame rate.

The higher the frame rate, the better. A video with a large frame rate value will have a large number of recorded images, and of course the amount of data will also be large. In addition, there are limits on the human eye, the side of the screen that projects it, and the technical specifications on the middle side, so it is necessary to set it to a suitable value.

Typical frame rates currently used are 24 fps, which is used for filming and animation, 29.97 fps, which is used for television broadcasts in Japan, and recent consumer cameras. There are 59.94 fps conventional, etc. Furthermore, there are also 25fps mainly for Europe.

What you want to know before making a video

Just as images have resolutions and file formats, there are some fixed formats and specifications for videos. Naturally, moving images, moving images, have more elements to define in the specifications, and the mechanism is complicated.
In fact, people in charge of marketing and promotion, advertising agencies, etc., can often feel disgusted by observing the presentation rules of each company.
This time, to dispel the weaknesses of those people, I would like to present a few main points that need to be understood in the video specs and the optimal video specs on major platforms like YouTube and Facebook.

1. Six Points Defining Video Specifications
Now, I would like to explain the six main points in the video specs.

1-1. Resolution
Like still images, videos have resolution. Image resolution refers to “size” and “pixel density”, but for moving images, resolution refers to “horizontal x vertical pixel count”.

The resolutions of familiar things are 720 x 480 SD image quality for DVD, 1920 x 1080 full HD for Blu-ray and 1440 x 1080 for digital terrestrial broadcast (* The reason why the aspect ratio is different from other will describe later).

Typical resolutions include
Full HD (1920 x 1080) / HD (1280 x 720) / SD (720 x 480) / 4K UHD (3840 x 2160)
.

Video resolution
Cameras like the iPhone X support 4K video recording and major streaming services like Netflix and Amazon Prime Video support 4K distribution.

Recently, with the expansion of smartphones and the rise of vertical signage, videos with long vertical resolutions and square videos like Instagram have also appeared.

Some people have said that “Full HD resolution is enough”, but the screen has gotten bigger, the price of 4K TVs has dropped, the drawing power of the smartphone screen has improved, and 4K / 8K has been improved. it has been generalized mainly by the Ministry of the Interior. Issues and Communications: As various efforts are made in this regard, it is expected that further progress will be made on a higher resolution.

1-2. Pixel aspect ratio
The pixel aspect ratio, also called the pixel ratio, represents the ratio of the width to the height of the pixels that make up the video data, and you can set the expansion / contraction ratio of the video during playback. Be careful as it is easy to confuse with the old resolution (aspect ratio of the video itself).

In digital terrestrial broadcasting, due to the compatibility with the conventional SD format and the amount of data, data with a resolution of 1440 x 1080 (4: 3) and a pixel aspect ratio of 4: 3 is distributed and stretched on the side of the TV. When doing so, the appearance is 16: 9, but it’s okay if you think you are basically using square pixels (1: 1) in WEB video.

1-3. File format (container), codec
To understand the file format of a video, you need to understand what is called a “codec.”

Audio and video data are stored in a “video file”.
In addition, data is compressed and encoded (also called encoding) using a “codec” so that it can be processed more efficiently and more easily by personal computer software.

In other words, when a video is played, it cannot be played unless the data is decompressed using the same “codec” as the “codec” used when compressing.

Note that the codec cannot be identified by the file extension alone. When making a request to a production company, be sure to also specify the codec.

To make it easier to understand, we will use “codec” as “key” and “video / audio data” as “treasure box”.

There are two treasure chests in the video archive, each locked with a different key. That is, to open the treasure chest and play the video, the key (= codec) corresponding to each treasure chest is required.

If you lock with “Key A” when generating video data and “Key B” when generating audio data, the video will play normally if you don’t have “Key A” and “Key B” in your hand. You can’t do it and if you only have “Key A”, you won’t be able to play the audio.

Most popular video formats

Most popular video formats

The data shows the frequency of use of formats by users around the world and takes into account more than 3 million conversions on a PC with Windows operating system and more than 450 thousand conversions on an OS X operating system.

Most video files are converted to MP4, AVI, and MOV formats.

We began collecting these statistics to better understand our users and their needs. For example, we made sure that there is a great need to save our own conversion parameters, so we continue to work on the convenience of configuration. This data also helps us to see the problems that arise with the decoding of certain files and to solve them quickly, says Anna Komarova, Product Manager of Movavi.

Among Windows PC users, a significant prevalence of MP4 and AVI formats can be noticed over all others, placing them first and second with 33% and 24%, respectively.

The MPEG-4 container, also known as MP4, was introduced by the International Organization for Standardization (IOS) in 2001 and has gained success due to its versatility: it allows you to encode both graphics and audio data, it is used to transmit video in Internet, and is compatible with most mobile devices, including smartphones, tablets, and game consoles.

The AVI container, introduced by Microsoft in 1992, has been in use for more than 20 years and is still very popular, despite the many shortcomings that have long been eliminated in more modern media containers.

The next most popular formats for the Windows platform are MOV (4.41% of the total number of conversions) and WMV (3.97%). The VOB format (3.67%), which is used to encode DVD-video, closes the top five.

Named after a traditional Russian toy and often used to convert high definition (HD) videos, the Matroska container is rarely chosen by users of the Movavi video converter – 1.72% of the time. The newer WebM and OGV formats that support HTML 5 are even less popular.

The success of MP4 is also confirmed by the statistics of “paired” formats: that is, from which format users most often translate video files into. First is the conversion of AVI files to MP4 (13.96%). The reverse pair MP4 → AVI is much less common (3.85%).

The preferences of Mac users differ from those of PC owners, although MP4 is also in the lead here, and even by a wide margin from the rest of the containers. Its participation is 58.16%, while the MOV format, developed and promoted by Apple, came in second place with almost four times less score of 14.24%. The AVI format is used by “macovods” 7 times less than by PC owners.

The audio format rankings on both platforms are predictably led by the ubiquitous MP3; second place went to WAV files. Rounding out the top five are WMA, OGG, and FLAC, which provide lossless compression.

It seems that the most important factor in the popularity of a video format is its versatility. Not surprising: we see video files not only on computers, but also on DVD and Blu-ray players, smartphones, tablets, or directly on smart TVs.

It is for this reason that the classification is dominated by the MPEG-4 standard, which now works on almost all devices. We pay less attention than before to the size of the movies, the high-speed Internet access allows you to successfully transfer videos that occupy several gigabytes.

What is the best video format for Youtube? Part 2

And again, I welcome you to my site. This is the second part of the article, in which I verify from my own experience which video format is best for YouTube.

In the last part, I reviewed the AVI (uncompressed) video format, marking the rendering results in a special table. Today we will consider two most popular video formats, MP4 and WMV, which also deserve our attention. Let us begin!

MP4
MP4, like AVI, is a container for audio and video files, which uses many codecs like H.264 and AVC to encode video. Again, as in the case of AVI, for the experiment I will take only one of them, which in Sony Vegas Pro is called MainConcept AVC / AAC (Internet HD 1080p), since it is ideal for publishing on the Internet, and therefore on YouTube. …

Representation
MainConcept AVC / AAC MP4 video playback took 5 minutes 1 second, which is almost half as long as in the case of AVI.

MP4 rendering time table

The size

But the video size in MP4 format is much smaller than in AVI format, and it is 129MB. I wonder how this affects its quality.

AVI size chart

Quality
In general, even considering that the video was encoded using the AVC codec, the quality did not suffer much. But something interesting was noticed in the way of increasing the contrast in one part of the video and decreasing it in the other.

Comparison of AVI and MP4

It clearly shows the difference between AVI and MP4 formats. Pay attention to the sky and the stump in the protagonist’s hands. This is what I wrote about above:

Contrast MP4

In my opinion, such video contrast, although it looks good, makes it uncomfortable for perception, so the final rating can be reduced by 2 points, that is, up to 8.

I have no complaints about the quality of the video, especially for such a small size of 129MB.

MP4 quality table

Conclusion: the MP4 (AVC / AAC) format has a small size and good quality, almost not inferior to the AVI format, but its strange contrast makes the video not very easy to read, which is a disadvantage of this format (although for some it may be an advantage).

What is the best video format for Youtube? #oneOnce again, I welcome you to my site! Today we will talk about which video format is the best for Youtube and how to choose the best video format for Youtube.

Choosing the optimal format for your videos is the main task of any video blogger. If you choose the wrong format for your videos, you can completely ruin the viewers’ impression on Youtube, even if it is in Full HD quality.

After all, no matter what quality the original video was recorded in, the most important thing is what quality it will have in an already “finished”, rendered form. Therefore, it is especially important in the initial stage to pay attention to the correct selection of the video format for YouTube, so that later it is not too late.

Everything that will be written in this article is based on my personal experience. The article will be written in plain text, without all kinds of unnecessary terms and definitions, that is, in simple and understandable language.

Since everything is learned in comparison, special attention will be paid to comparing video formats with each other. In the article you will learn about the pros and cons of the three most popular video formats, and towards the end I will conclude which video format is the best for Youtube.

Like my guinea pig, I will take a Minecraft video at 1920 x 1080 resolution, 1 minute and 15 seconds long and 29,970 frame rate, recorded with Fraps in AVI format. That is, a “clean” video for experiments.

I will process (render) the video in the Sony Vegas Pro program.

The technical characteristics of the equipment in which I will carry out the experiment are the following: AMD Phenom II X4 945 processor, 4.0GB RAM, AMD Radeon HD 7800 Series (HD 7850).

What are video codecs and audio codecs?

What are video codecs and audio codecs?

You probably encountered a problem when the player refused to open a file, a dark screen was displayed while viewing, or the video played without audio. This happens when there are no codecs on the device. Also, errors can occur when using outdated equipment. Let’s take a look at how to solve the problem and install compatible video codecs for Windows 7 and other versions of the operating system.

What are codecs?

The name “codec” is a combination of the words “encoding” and “decoding” (co / dec). Technically, this is software used to compress and decompress a digital media file (music or video). They are needed to compress video, image and sound files to the smallest size so that the file takes up less space and is faster to transfer over the Internet. Windows Media Player and other programs use codecs to play multimedia files.

Sometimes they get confused with the video format or container. But a media container is a collection of files that stores data compressed by a video codec. AVI movie is a container that contains multimedia files encoded with XviD, DivX or MPEG-2.

How do codecs work?

Codecs are used to change media format or reduce file size for fast transmission over the Internet. They do the opposite, “reading” data from MP3 or other formats for playback. This is called unpacking.

The process of creating an encoded video file
The process of creating an encoded video file
There are two types of compression. Lossless codecs compress the original video at the highest quality settings. This can be compared to packing files in a ZIP file: after unzipping (when watching a recoded video), the output file does not differ from the original. These multimedia files are great.

Lossy codecs lose information to varying degrees, which leads to degradation of the quality of the processed media file. But they save a lot of space on your hard drive. Modern converters allow you to set optimal compression settings and minimize losses.

What codec should I choose?

If the required codecs are not found when playing media files, the player displays an error indicating the problem. It remains to find a solution on the Internet. However, the software does not always indicate the missing video codec.

Codec message is missing in Windows 10 Movies & TV Player
There are hundreds of options for different purposes: audio and video compression, media streaming, video conferencing, MP3 playback, screenshot. Let’s consider the popular codecs for watching videos and playing music files.

MPEG. MPEG-1 offers high quality video and creates MP3 sound that plays on all modern music devices without exception. MPEG-2 is the current video compression standard for DVD and Blu-ray discs. MPEG-4 provides better compression methods and smaller output video sizes.
H.264. The most popular option for HD video, which can use lossy and lossless compression. H.264 is 2 times more efficient than MPEG-4 and produces a smaller file with smoother playback. H.264 is used for web video and Blu-ray recording.
XVID / DIVX. DivX is a commercial codec, XviD is an open source alternative. DivX can compress long video segments into small sizes while maintaining high quality.
HEVC. High-efficiency video coding (HEVC or H.265) is a new compression standard. This “cousin” of H.264 makes even better use of its compression algorithms. The codec is only gaining popularity and is not supported by all programs.
How do I install and run codecs?
You do not need to download the codecs separately. There are many packages that contain the necessary audio and video codecs. The most popular variant of the K-Lite Codec Pack. It is distributed free of charge in various trim levels, from basic to advanced, and includes Media Player Classic.

The 5 most popular video formats

The 5 most popular video formats

Certainly, it is impossible to give a simple answer as to which video format is the best. But you can offer users a choice by listing various popular extensions, their advantages and disadvantages.

AVI. This is the most popular container developed by Microsoft. This type of file can store audio, video, text, and graphics at the same time. The main advantage of AVI is that it is compatible with almost all popular players and modern devices.

MKV. Also known as “Matroska”. It is also a container that can include videos, audio, subtitles, and animated menus. In part, this format is similar to AVI and most of the time it plays smoothly on a PC. But if you downloaded a movie in this format and want to watch it on TV, prepare yourself for a nasty surprise. You most likely cannot do this, because this extension is not readable by most TV models. .

MOV. The best video format for macOS. The video on it is recorded from cameras and digital cameras. In some cases, to open video files of this format, users must install an additional QuickTime Player on their PC.

FLV. This format is common on video hosting sites like RuTube, YouTube, Google Video, and others. The advantage of these videos is that even at low bit rates, they are of good quality. On older PCs, it is sometimes difficult to reproduce this format.

VOB. It is an extension of the container, in which several audio and video streams, as well as subtitles and menus, can be collected at the same time. Most of the time VOB is used when converting video to DVD.

What is the best format to save the video?

What is the best format to save the video?

To reduce the “weight” of the video, various video formats are created using different compression algorithms. Thanks to this technology, a video file can be compressed hundreds of times without loss of image and sound quality.

Today, in addition to the widespread DVD video format, there are many types of video formats that differ in video encoding method and file size.

DVD video
DVD video playback requires a DVD drive and an MPEG-2 decoder (that is, a consumer DVD player with a hardware decoder or a computer DVD drive and a software player with a decoder installed). DVD movies are compressed using the MPEG-2 algorithm for video and various formats (often multi-channel) for audio. The compressed video bit rate (bit rate) ranges from 2000 to 9800 Kbps, often variable (VBR). The standard video frame size of PAL standard is 720×576 pixels, NTSC standard is 720×480 pixels.

It can be viewed on a DVD player and computer, as well as smart devices.

MPEG-2
In reality, MPEG-2 is not just a digital format, but a group of standards used to encode and compress video and audio data. It is most often used to process video intended for DVD recording, as well as to organize the transmission of a multimedia transmission through digital television channels. MPEG-2 encoded videos typically play at around 25-30 frames per second. Compression of the audio backing frames can be performed on multiple channels.

It can be viewed on the computer and on smart devices.

MPEG-4
The MPEG-4 format was created in 1998. The purpose of its creation was the prospect of greater compression of digital audio and video, so that an MPEG-2 movie fits on a DVD disc, but the same movie in compression format MPEG-4 fits freely on a CD, the capacity of which is 6 times less.

The MPEG-4 format, like MPEG-2, stores only the frames in which the image in the frame has changed greatly. But this format does not store intermediate frames, such as MPEG-2. Instead, the MPEG-4 file stores data about changes (also about expected changes) in the image between two control frames (key). Information received about changes can be compressed in the same way that the file is compressed by programs designed to archive data.

This format has a large number of varieties and is used in various video playback devices.

MPEG-4 is an international standard approved by ISO, the international standards organization. It is usually used to compress digital audio and video, for streaming (video streaming), movie recording, in video telephony and streaming, in a word, where digital video and audio compression is actively used.

It can be viewed on the computer and on smart devices.

Windows Media
This format (Windows Media) was developed by the well-known company Microsoft and is intended to store compressed audio and video. This compression format is capable of providing high quality video and sound, which in some cases exceeds the quality of DivX and MPEG-2, but is basically identical, and this is with a less complex compression algorithm.

Another advantage of this codec is that all the necessary software (codecs, decoders) is already installed in Windows operating systems, making it easy for users to find and install software and easily view it in the built-in Windows player: Windows Media Player or devices. smart.

Containers
Many people confuse concepts like “container” and “format” of a file. Often in my environment, phrases like “AVI file format” fly by. This expression is not entirely correct, although AVI is a long-standing file format. But files with the AVI extension can contain uncompressed video of various formats: MPEG-4, DV, DivX, Xvid, and of course MPEG-1 and MPEG-2. Also, the AVI format can only contain audio. This tells us that AVI files are containers for content in various formats.

A container is a file that has some kind of extension that is used to store analog information converted to digital format. Some containers store service information. For example, a video file can include captions that are inherently not part of the video image, but only plain text. Many players have a feature to enable and disable the display of titles in the frame. Summarizing, we can conclude that a container is a file of a certain

What is video format and which one is better?

What is video format and which one is better?

Digital video is increasingly included in our lives, and if a few years ago users were limited to watching movies and videos on the Internet, now these same users create video content themselves, and in such quantity that even film studios Hollywood couldn’t. Sound.

Private video clips have filled social media Vkontakte, Facebook and now Instagram, Youtube video hosting is packed with newly created video channels and gigabytes of video uploaded to them.

Thanks to modern devices and software, it has become as easy as possible to work with video: editing, pasting, layering sound, as well as converting from one format to another, all of this is now done literally in a few clicks and does not require the user has extensive knowledge of the technical part of the process itself … Perhaps, if that requires a little excursion, then these are video formats like MP4, AVI, WMV, MOV, as well as MKV (M2TS). Next, we will talk about what a video format is and take a closer look at each of them.

What is the video format?
The video format is the structure of the video data, how it is stored on the memory card, and with which video codecs it is encrypted. Depending on the format: MP4, AVI, etc., the structure of the video files may differ significantly from each other. The structure is a container for the separate storage of audio, video, and text data, as well as service metadata. Some video formats, in their structure, can store several audio or video tracks, with different quality and sound. When watching, using a video player, the user can select one or another track to play (for example, in Russian or English).

video file structure

All data, both audio and video, is encoded with special audiovisual codecs, such as AAC and H.264. Depending on the quality of the sound and video, the size of the file, as well as the resource requirements of the device on which this file is played, may change.

Let’s look at various video formats and find out which video format is better, for this we will compare video formats on three parameters: quality, processing (playback) speed, and video file size.

All video formats
AVI
The oldest presented format is a Microsoft development, it supports multi-streaming audio and video, it can contain data encoded by various video codecs. The main advantage is video playback on low-power devices, achieved due to the low compression ratio, from which the second advantage arises – good quality. However, the video file size is poor.

Video processing speed: 8 points (high);
Video file size: 1 point (low score);
Video quality: 8 points (good).
Overall score of 17 points.

MP4
It stands for MPEG-4 Part 14 and it is one of the most common formats. Today it is difficult to find a video device or video application that does not support this format.

Video processing speed: 6 points (average);
Video file size: 6 points (average);
Video quality is 7 points (above average), during viewing, you may notice “apostrophes”, changes in shadows and contrast.
The total score is 19 points.

WMV
Another Microsoft development, the format that replaced AVI at the time, is proprietary and used only in the Windows operating system, but it is also quite widespread. The main advantages are the small file size and high video quality, while this format is quite demanding on device resources due to the high degree of data compression.

Video processing speed: 2 points (average);
Video file size: 8 points (average);
Video quality is 8 points (above average), during viewing, you may notice “apostrophes”, changes in shadows and contrast.
The total score is 18 points.

Conclution
We found out what video formats are, what they are and what they consist of, and we also examined some of them, comparing them in more detail according to three main criteria. In the benchmarks, the title of the best video format to date is MP4, with an overall rating of 19 points. Acceptable video processing speed, good quality and average video file size. Obviously, it is thanks to these qualities that this format has gained such popularity among users. So, if you have AVI video that takes up a lot of hard drive space.
