Supported Video & Audio Formats
These formats are primarily used for compressing rendered sequences into a playable movie (they can also be used to make plain audio files).
A codec is a little routine that compresses the video so that it will fit on a Blu-ray, or be able to be streamed out over the Internet, over a cable, or just be a reasonable file size. Codecs compress the channels of a video down to save space and enable continuous playback. Lossy codecs make smaller files at the expense of image quality, while lossless codecs compress as much as possible the video, but without losing any existing data.
Some codecs, like H.264, are great for larger images. Codecs are used to encode and decode the movie, and so must be present on both the encoding machine (Blender) and the target machine. The results of the encoding are stored in a container file.
There are dozens, if not hundreds, of codecs, including Xvid, H.264, DivX, Microsoft, and so on. Each has advantages and disadvantages, and compatibility with different players on different operating systems.
Most codecs can only compress the RGB or YUV colors, but some support the Alpha channel as well. Codecs that support RGBA include:
Blender offers three ways to export videos, in the File Format selector of the Output properties:
- AVI JPEG
AVI but with JPEG compression. Lossy, smaller files but not as small as you can get with a Codec compression algorithm. JPEG compression is also the one used in the DV format used in digital camcorders.
- AVI Raw
Audio-Video Interlaced (AVI) uncompressed frames.
- FFmpeg Video
Video encoding via the FFmpeg library. Which codecs are available depends on the operating system and FFmpeg version. This options allows for a lot of different encodings, some presets are available (to the right of the Encoding subpanel) to help with getting started. This option is also the only one allowing to export audio.
A standard for lossy compression of video and audio. It is designed to compress VHS-quality raw digital video and CD audio down to 1.5 Mbit/s. This container enforces the video codec, you can only define quality parameters, and the audio codec.
A standard for «the generic coding of moving pictures and associated audio information». It describes a combination of lossy video compression and lossy audio data compression methods which permit storage and transmission of movies using currently available storage media (notably DVDs) and transmission bandwidth. This container enforces the video codec, you can only define quality parameters, and the audio codec.
While being a video codec, it is also a real container, in which you can store video and audio streams using various codecs. It is widely supported by many modern software and hardware players.
A derivative of the Resource Interchange File Format (RIFF). One of the first and most widely used video container format.
A multi-tracks format. QuickTime and MP4 container formats can use the same codecs. They are mostly interchangeable in a QuickTime-only environment. MP4, being an international standard, has more support.
An intra-frame video compression scheme, used by many digital camcorders back in the days. It uses the discrete cosine transform (DCT, similar algorithm to JPEG) to compress video on a frame-by-frame basis. Audio is stored uncompressed. This container enforces the video codec, you can only define quality parameters.
A free open-standard container format, that can hold an unlimited number of video, audio, picture or subtitle tracks in one file.
A free open-standard container format, a file format that can hold an unlimited number of video, audio, picture or subtitle tracks in one file.
A container file format used to deliver video over the Internet using Adobe Flash Player. This container enforces the video codec, you can only define quality parameters.
A free open-standard container format, designed to be used for internet streaming. Note that this container can only hold a VP9 video codec, and Vorbis or Opus audio codecs.
FFmpeg Video Codecs
These options are not available with all Containers.
- No Video
For audio-only encoding.
Intended to be usable as both an intermediate format suitable for use while editing, and as a presentation format. It can be either lossless or lossy.
- FFmpeg video codec #1
FFV1 is a lossless intra-frame video codec. It can use either variable length coding or arithmetic coding for entropy coding. The encoder and decoder are part of the free, open-source library libavcodec in FFmpeg. Supports an alpha channel.
- Flash Video
A modern variation of the MPEG-4 family, this lossy codec is very commonly used. It offers a very good compression/quality ratio.
Lossless video codec created by Ben Rudiak-Gould which is meant to replace uncompressed YCbCr as a video capture format.
Inherits many of the features of MPEG-1, MPEG-2 and other related standards, but also adds new features.
Lossless, this stores each frame as an independent image in the video stream. Compression will be poor, but as every frame is fully self-contained, scrubbing and editing can be simpler. Supports an alpha channel.
- QT rle / QT Animation
Original format of QuickTime videos. Supports an alpha channel.
A free open-standard lossy codec designed together with the Ogg container.
- WEBM / VP9
A free open-standard lossy video compression format. One of the most recent codecs, it is widely used for internet streaming.
A free open-standard lossy video compression format, designed as a successor to VP9. AV1 offers great compression rates and visual quality, AV1 produces video files that are about 30% more space efficient than VP9
FFmpeg Audio Codecs
- No Audio
For video-only encoding.
Advanced Audio Codec, a standardized, lossy compression and encoding scheme for digital audio. AAC generally achieves better sound quality than MP3 at similar bit rates.
Audio Codec 3, an audio compression technology developed by Dolby Laboratories.
Free Lossless Audio Codec. Digital audio compressed by FLAC’s algorithm can typically be reduced to 50-60% of its original size.
A lossy audio compression format.
A lossy audio compression format, widely used as final audio format.
A lossy audio compression format, designed to encode speech or general audio and is intended to replace the Vorbis codec.
Pulse Code Modulation, a method used to digitally represent sampled analog signals. It is the standard form for digital audio in computers and various Blu-ray, Compact Disc and DVD formats, as well as other uses such as digital telephone systems.
An open-standard, highly-compressed format comparable to MP3 or AAC. Vorbis generally achieves better sound quality than MP3 at similar bit rates.
Video Output Size
Some codecs impose limitations on output size,
H.264, for example requires both the height and width to be divisible by 2.
