What is video format and which one is better?

If you went in and read this text, it is likely that you have already encountered the difficulties of video playback and the concept of video format. In this article, I would like to highlight common questions about what is a video format, what formats are there, and what is their difference, as well as give advice on how to choose the most convenient format to store your video.

Generally speaking, a video file is a set of still images that switch between each other at a certain frequency. Each image is a separate video frame. This is true when it comes to uncompressed videos. These video files take up a lot of disk space and it doesn’t always make sense to store them. And it makes sense when the video is of optimal quality and size. We can achieve this by using the desired format.

What is the video format?

The video format is determined by two parameters: a container file (in which the recording is stored) and the codecs (used to process sound and images)

What is a container file?

Consider the video recording process on any digital video camera. A video camera records sound and video in separate sequences (tracks), encoding each of them with a special program: a codec. Then both tracks are put into a special file, the same container file, where they are given a description. This information will further help the media player to correctly synchronize the image and sound when playing a video.

What is a codec?
A codec is a program that compresses when recording and decompresses multimedia information during playback: audio, video, etc.

So how are the formats different?

The content of the container file. For example, you can put multiple audio tracks and subtitles in an AVI container. And in the MKV container, you can pack whatever you want: any number of video and audio tracks, animated and test subtitles, fonts for them, and much more.

Codecs used. Despite the wide variety of codecs, each format is “friendly” or compatible only with certain audio and video codecs.

For example, an MPEG container only allows video compressed with MPEG-1 or MPEG-2 codecs. But its younger cousin, the MP4 container, is less demanding on connections: here the choice of codecs will be wider.

Many others stem from these two basic differences:

File size
video resolution
the ability to play videos online
picture quality
other…
There are formats that produce ultra-clear images and great sound, but take up a lot of disk space, and there are formats that cannot boast of video image quality, but take up very little space. Therefore, to the question: “Which of the video formats is better?” – everyone must answer for themselves. Depending on the characteristics of the device on which the movie or clip will be viewed, the best quality, the “clearest” or, for example, the most common format may be the best.

We recommend that you choose for yourself several “on duty” formats, which will be adapted to each one according to your needs. Here are the format guidelines for different storage locations.

Video for online storage:
YouTube, Vk, Facebook, Vimeo
Please use MP4 format with H.264 and AAC codecs. This setting provides the highest video quality with the smallest file size.
Other places
Most modern sites are “compatible” with MP4, FLV, AVI, and WebM, so choose one of them.
Video storage on computer:
If you have a powerful computer (see the specs below), protect your recording in MKV or MTS (M2TS) and enjoy excellent picture and sound quality
Intel, AMD (or compatible) processor with a frequency of at least 1 GHz.
1280×1024 screen resolution, 32-bit color (or higher).
1 GB of RAM for Windows XP, 2 GB for Vista, Windows 7 and 8.
NVIDIA® graphics with CUDA ™ technology support.
If your computer does not meet the above specifications, save the video with a video resolution of no more than 960×540 pixels in MP4, AVI, WMV format if it is Windows OS and MOV or MP4 if you have Mac OS X.
Video for storage on a mobile device:
Convert video for mobile phone with video converter. I recommend FormatFactory. It has many presets for popular models and a simple interface to help you convert your videos to the format you want.

Personally, I think that you should focus on popular video hosting sites like YouTube and Vimeo anyway, and compress videos with compression parameters similar to what these two giants use at home.

WHICH VIDEO FORMAT IS BEST AND WHY: A DETAILED DESCRIPTION

WHICH VIDEO FORMAT IS BEST AND WHY: A DETAILED DESCRIPTION

Not all video fans understand how some video formats differ from others. And in vain! After all, if you accidentally or intentionally install the wrong extension in the video editor while saving the project, then serious difficulties with the clip playback can arise. In this article, you will learn about the features of popular extensions and when and which one to choose.

What video format is better?

Learn about the characteristics of the formats, then you can watch videos on any device!

WHAT IS FORMAT
The format is the structure used to store data. Its designation is an identifier, separated by a period at the end of the name: .wmv, .avi, .mp4, etc.

For a video file, the media container and codec are responsible for the extension. When recording or rendering a movie, the data, including individual frames and an audio track, is compressed and placed in a special container. For later playback, the same video codec is used, which can decode information and display it in its original (or almost original) form. The media container itself cannot determine how the data is encoded, but it works fine with certain codecs. It also stores meta information about the object: size, duration, author, etc.

Both codecs and multimedia containers are involved in the recording and playback process, but the format is indicated precisely by the type of container used: AVI, MPEG-4, MKV and others. Codecs also have their own names: H.264, DivX, Theora. But most of the time they are distributed in packages, and the description does not indicate their names, but the media containers with which they work. This is a simplified answer to the question of what is a format. A more complex one involves many terms that are unnecessary for the average user.

WHAT ARE THE DIFFERENCES BETWEEN CONTAINERS?
In the simplest cases, they only store video and audio streams. In more complex ones, you can save multiple video tracks, synced subtitles, and chapter marks for quick navigation through content.

When choosing which format is best for converting video, you need to remember that certain media containers are used for minimal compression to get an accurate image, but this often results in a large size. Others compress the material more, saving space on the media. Some of them support tracks that are only compressed in specific ways. For example, MPEG-4 Part 14 works with files compressed with H.265 / HEVC, H.264 / AVC, and MPEG-4 Part 2.

WHICH VIDEO FORMAT IS BEST?
Almost any of the extensions have their own advantages, otherwise their existence would be meaningless. But when creating your own movie or, for example, choosing a movie to watch, you have to rely on two components: opportunity and prevalence.

Choose the format according to the device you will see the video on

Capacities mean the number of video tracks that will be stored there, subtitles, chapters, and more. The prevalence depends on the probability that a movie will run on a device without installing additional codecs. If you directly answer the question of which video format is better, then the answer will be one of the three most common: AVI, MKV or MP4.

What video format is better?

At the moment, you have a wide variety of options for storing and presenting digital multimedia information. There are many different video formats, each with its own unique characteristics. In such a situation, a natural question arises, which video format is better?

To convert any information into digital form, special programs are used – codecs. They create a special file – a container in which all the data is stored. These two concepts should not be confused, as they perform completely different functions.

The following codec definition can be found on Wikipedia. A codec is a special computer program that converts a stream of data or a signal for later use. Codecs transform the information available to store it more optimally and compactly. In this case, the main structure of the file (container) remains the same, only the way the data is presented changes. The most popular codecs for video recording are: DivX, XviD, MPEG2, H.264, etc. If you decide to record a movie or, for example, create a slide show online, you must decide which video codec to use.

XviD is a modern MPEG4 codec. Allows you to obtain high definition images in dynamic scenes. Therefore, when choosing a codec, proceed from the characteristics and characteristics of the video file itself. This will allow you to understand which video format is best for a particular case. Unlike DivX, XviD is free software released under the GNU license.

DivX is one of the most popular video codecs. Provides high-quality images. The files converted with this codec are small and can be viewed on almost all modern DVD players. As of the fifth version, you paid for encoding.

H.264. Compared to the two previous video codecs, H.264 is more efficient and provides higher compression rates without sacrificing quality. However, as a general rule, this codec is absent from the computer initially and must be installed additionally.

MPEG2 is a popular video standard that is actively used in digital television to provide high-speed information transmission. In addition, the MPEG2 codec is used when recording DVD discs, as well as in video compression systems.

Let’s say you are faced with a specific practical task: creating a video slideshow. What is the best video format to record? First of all, you need to proceed from where you will use the created video file. For example, if you want to put a finished video on any video hosting service, use the H.264 codec, which allows you to get a significant degree of data compression with minimal loss of quality. AMS Software’s PhotoSHOW slideshow maker includes a full set of modern video codecs and enables you to make spectacular slideshows from professional-quality photos.

The codecs then convert the information into a special file called a container. A container is a kind of shell in which the information converted by codecs is stored digitally. The container structure is heterogeneous and includes several components: video stream, audio stream, various additional information (file information, titles, etc.). Therefore, the container itself cannot convert information, it only serves to store it. The most common containers are AVI, TS, MP4, MKV. Let’s look at some of them in more detail to answer the question, which video format is the best?

AVI (Audio-Video Interleaved): literally means “interlaced audio and video”. It is a universal container for storing information of various types. The AVI file can contain video, sound, text information, etc. Also, there can be multiple audio streams. When creating an AVI file, a wide variety of codecs can be used. This video format is superior to similar video standards due to the ease of use and the wide range of video recording capabilities.

MKV is a freely distributed container known as the “Matroska” project. This multimedia container allows you to store a large amount of a wide variety of information, including audio tracks in different languages, subtitles, it allows you to create special video chapters, etc. The main characteristic of this format is the openness of the code, which allows programmers from all over the world to edit and improve it. When comparing AVI with MKV, the latter video format is better than the former in most parameters. MKV container has all the necessary parameters to store video files and is becoming more and more popular

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 quantities that not even film studios Hollywood could dream. Private video clips have filled the social networks 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, working with video has become as easy as possible: 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. … Maybe yes, which 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 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, for example 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 the 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. Also, before proceeding to the comparison, it is worth noting that you can always convert videos from one format to another using Movavi Video Converter.

All video formats
AVI
The oldest presented format is a Microsoft development, supports multi-stream audio and video, 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. But the size of the video file leaves a lot to be desired.

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), while viewing it, you may notice “apostrophes”, changes in shadows and contrast.
Overall rating of 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.

conclusion
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 based on 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.
