What formats does windows media support. Windows Media Player can't play the file - what to do. What is a codec

Video video file format — defines the structure of the video file. There are many formats for encoding and compressing video files, consider some of them or Almost all.

At the end of 2008, there are three main video file formats: avi, mpg and mov.

Let's analyze each in a little more detail.

ASF format(Active Streaming Format) is a streaming format from Microsoft.

Commonly used video file extension.asf.

ASF video files appear with the extensions .wma or .wmv.

ASF is a multimedia container, and does not specify how the data should be encoded, but only defines the structure of the data stream. In this regard, ASF replaces the AVI media container format.

go.microsoft.com/fwlink/?LinkId=31334 - ASF Specification

AVI format(Audio-Video Interleaved) developed by Microsoft for storing and playing videos, is a container that can contain anything from MPEG1 to MPEG4.

It can contain four types of streams - Video, Audio, MIDI, Text.

Commonly used video file extension.avi.

There can be only one video stream, and several audio streams.

AVI can contain only one stream - either video or audio.

AVI does not impose any restrictions on the type of codec used, neither for video nor for audio - they can be anything.

AVI video files can combine any video and audio codecs. AVI uses less compression than similar video file formats.

AVI video files can be played by various players, but the player must support the codec used to encode the video.

Questions often arise: who adopted the avi standard
or avi standard is developed by whom. This RIFF media container was first used by Microsoft in 1992 for reference.

AVI video files often use the following video codecs:

DivX Codec www.divx.com

Cinepak Codec www.cinepak.com

Codec Indeo www.ligos.com

DV codec

MJPEG codec

Uncompressed RGB or YUY2 codec

AVI video files often use the following audio codecs:

MP3 codec

MS ADPCM codec (Microsoft Adaptive Differential Pulse Code Modulation)

PCM codec (Uncompressed Pulse Code Modulation)

DivX format(Digital video express) - Mpeg4 standard codec.

www.divx.com

FLV format(Flash Video) - Video files used to transfer videos over the Internet. Used by services such as YouTube, Google Video, RuTube, Tube.BY, Movies, Obivu, etc.

FLV video files can be viewed on most operating systems because it uses Adobe Flash and plug-ins for most browsers, and is supported by many DirectShow video playback programs.

MOV format- Apple Quicktime, can contain any codec, CBR or VBR. They usually have a .QT or .MOV extension.

Since the MPEG4 Group has chosen QuickTime as the recommended format for MPEG4, their MOV video files come with an .mpg or .mp4 extension.

MPG format(Moving Pictures Experts Group) — A video file that contains videos encoded by:

MPEG1 format- the standard was developed in 1992, taking into account the capabilities of 2-speed CD-ROM and 486 computers.

This standard allows you to encode video data at a bit rate of about 1.5 million bits per second (bps). This format was developed specifically for use on Video-CD and CD-i CDs. Most implementations of the MPEG-1 standard provide playback at 352×240 pixels at 30 frames per second (fps). When using this standard, the image quality is slightly worse than that obtained using a conventional VCR.

MPEG2 format The standard was adopted in 1994. It was originally developed for broadcast-quality digital video transmission. Used in DVD, digital TV and HDTV.

MPEG3 format- for high-definition television (HDTV), but later became part of the Mpeg2 standard and is no longer mentioned separately.

Mpeg4(short spelling MP4 is common) - the standard is designed for very low flows data for use in video phones, multimedia e-mail, electronic information publications, etc.

MPEG1-2 (MPG)– a video and audio storage format with compression and data loss.

MPEG4 (MP4)– a movie or video clip compressed in the MPEG-4 standard, commonly used for the exchange and transmission of video files on the Internet,video phones, multimedia e-mail, electronic information publications, etc. This format uses separate compression for audio and video tracks.

MP4 is designed for very low data rates.

The MPEG-4 format is an International Standards Organization (ISO) standard that describes various aspects of multimedia data presentation, including data creation, compression, and transmission.

Book.itep.ru/2/25/mpeg-4R.htm

That said, although compression and containerization of data in a video file are described by two different independent parts of the MPEG-4 standard, many people incorrectly think that they are interchangeable. Thus, it is possible to only partially implement the requirements of the standard and at the same time remain within its framework.
support.microsoft.com/kb/316992

According to the MPEG-4 standard, MPEG-4 video files contain video data compressed using MPEG-4 methods and audio data compressed using Advanced Audio Coding (AAC).

Typically, these video files have an MP4 extension. Windows Media Player does not support playback of these video files. To play MP4 video files with Windows Media Player, you must install an MPEG-4 decoder compatible with DirectShow. Such decoders are included in the Ligos LSX-MPEG Player and EnvivioTV packages.For more information about the Ligos LSX-MPEG Player, visit the Ligos website at the following address:

Note

Moving Pictures Experts Group (MPG, MPEG, M1V, MP2, MP3, MPA, MPE, MPV2, M3U)

The Moving Picture Experts Group (MPEG) standards were developed by an expert group of the same name. It is an evolving set of audio and video compression standards.

WMV format(Windows Media Video) — A video file recorded in the Windows Media format.
Windows Media Video (WMV) files are Advanced Systems Format (ASF) files containing audio, video, or mixed recordings packaged using the Windows Media Audio (WMA) and Windows Media Video (WMV) codecs.

Using a separate extension allows you to install several players on your computer and use some of them to play video files with the WMV extension.

video files for 3rd generation mobile phones. Some modern mobile phones (not necessarily 3G) have the ability to record and view audio and video in .3GP format.
This format is a simplified version of the ISO 14496-1 Media Format, which is similar to MOV used by QuickTime.
3gp saves video as Mpeg4 or H.263. Audio is saved in AMR-NB or AAC-LC formats.
Finished videos 3gp videos are small compared to other video formats, but this affects the quality.

LOW INTELLIGENCE

Video file formats define the structure of the video, i.e. reflect how the file is stored on any storage medium. There is currently great amount various video file formats, and understanding their features can sometimes be quite difficult. In addition, users often confuse the concepts of "codec", "container", "video standard" and substitute one for the other.

AT this article we will try to figure out what video formats are, what are their differences, and what format is best to convert video to.

Video codecs

Used to compress digital media files special programs- codecs. This is a kind of formula that determines how you can "package" video content. Codecs also perform the reverse decoding operation, in which case they are called decoders.

The most popular video codecs are the following: DivX, XviD, H.261, H.263, H.264, etc. Any operating system initially contains a certain set of codecs, but, as a rule, they are not enough to play certain video file formats.

Video containers

Codecs convert the data into a special file called a container. A container is a special shell that stores information encrypted using codecs. In fact, media containers are video file formats that contain data about their internal structure. The first media container was created in 1985.

Information can be stored in a container different quality in particular images, audio, video and subtitles. Different types containers determine the amount and quality of information that can be stored in it, but do not affect how data is encoded.

Format conversion

In practice, there are a huge number of cases when it is necessary to convert video from one format to another. The main problem is that different devices impose special requirements on the quality of the downloaded video, in particular on its format. In this situation, special programs come to the rescue - converters that allow you to convert the video to the desired format. For example, convenient - VideoMASTER.

AVI

Audio Video Interleaved- one of the most common media containers for Windows operating systems. This format can contain four types of information: video, audio, text and midi. This container can include videos of various formats from MPEG-1 to MPEG-4.

AVI has a large number of varieties in terms of internal structure and can be played on smartphones, communicators and other devices. The AVI media container does not impose any restrictions on the type of codec used.

WMV

Windows Media Video- digital video format created and controlled by Microsoft. WMV files may contain audio and video data packed with Windows Media Audio (WMA) and Windows Media Video (WMV) codecs.

MOV and QT

QuickTime File Format- this format is designed by Apple for QuickTime media player. To play such files, you must have a QuickTime player or players with MOV codecs already installed. The format can contain video, animation, graphics, 3D. This format supports any audio and video codecs.

ASF

Advanced Streaming Format- streaming format from Microsoft. Based on MPEG-4 and used for low to medium bitrate video transmission over the Internet. ASF is a multimedia container that supports almost all video codecs.

MPEG

Moving Pictures Experts Group- video files containing video encoded using Mpeg1, Mpeg2, Mpeg3, Mpeg4 standards. MPEG technology uses streaming video compression, which does not process each frame separately, but analyzes changes in video fragments and removes redundant information. MPEG-1 is a format for storing audio and video data on multimedia media.

The MPEG-4 format is commonly used for the exchange and transmission of video files on the Internet, video telephony, electronic information publications, and the like. This format uses separate compression for audio and video tracks. MPEG-4 is designed for very low data rates.

Conclusion

We have listed only the most basic video file formats that are used in practice. When choosing one or another format, proceed from where this file will be played, and use video converters to convert video from one format to another.

You probably noticed that different videos files are in various formats. Why are there so many different video file formats?

Because initially these formats were developed for different purposes. Some formats can store multiple audio tracks and subtitles, and other file formats do not have this option. Some formats are more suitable for broadcasting, while other formats are more suitable for editing.

This article will briefly describe the most popular video file formats.

Video file standards

First of all, these are standards that have been developed by various international organizations and which define the encoding and storage format of the media file data.

MPEG-1 (Moving Picture Experts Group 1) are video and audio compression standards. For video, the Video CD format is used, and for audio, the MPEG audio layer 3 format, or the well-known MP3 format for short, is used. This is the most compatible format for playing on computers with CD/DVD optical drives.
MPEG-2 (Moving Picture Experts Group 2) - this standard is used in DVD and digital television DBV. In this format, video is shot in various devices for shooting video.
MPEG-3 (Moving Picture Experts Group 3) - This standard was developed for HDTV, and has now become part of the MPEG-2 standard.
MPEG-4 (Moving Picture Experts Group 4) - This standard is used to compress digital video and audio. Consists of several standards, includes many features of MPEG-1 and MPEG-2. This standard uses various codecs: DivX, Xvid, H.264 (AVC) and others. The MP4 format is one of the specifications of this standard.

A media file has several characteristics that determine the work with this file. This is the codec that this media file is encoded with and the container type that determines the recording format using various information: video and audio data, subtitles and other information placed in the container.

Example codecs - DivX, Xvid, H.264, Theora.
Example containers - Matroska, AVI, QuickTime, Ogg, 3GP.

Video file formats

And now let's look at the most common video file formats. After installing the codec pack, almost all the formats discussed in the article will have to be played by a standard player - Windows Media Player installed in the Windows operating system. Along with the K-Lite Codec Pack, Media Player Classic Home Cinema is installed, which will also play almost all of these video file formats.
