Supported Video & Audio Formats¶
Формати Відео – Video Formats¶
Ці формати, перш за все, використовуються для стискування рендерених послідовностей у грайноздатний фільм (вони можуть також використовуватися для вироблення звичайних аудіо файлів).
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.
Примітка
Most codecs can only compress the RGB or YUV Color Space, but some support the Alpha channel as well. Codecs that support RGBA include:
Quicktime
PNG TIFF Pixlet не є безвтратним і може бути доступний лише на macOS.
WebM/VP9 (although Blender will not import the alpha channel due to a limitation of FFmpeg).
Blender пропонує три способи експорту відео, у вибірнику «Формат Файлу» – File Format властивостей «Вивід» – Output:
- 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
Аудіо-Відео Черговані нестиснені кадри – Audio-Video Interlaced (AVI).
- 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.
Контейнери FFmpeg – FFmpeg Containers¶
- MPEG-1:
.mpg,.mpeg 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.
- MPEG-2:
.dvd,.vob,.mpg,.mpeg 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.
- MPEG-4:
.mp4,.mpg,.mpeg 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.
- AVI:
.avi A derivative of the Resource Interchange File Format (RIFF). One of the first and most widely used video container format.
- Quicktime:
.mov 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.
- DV:
.dv 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.
- Ogg:
.ogg,.ogv Безплатний формат контейнера відкритого стандарту, що може містити необмежену кількість стежок відео, аудіо, зображень або підтитрів в одному файлі.
- Matroska:
.mkv Безплатний формат контейнера відкритого стандарту, формат файлів, що може містити необмежену кількість стежок відео, аудіо, зображень або підтитрів в одному файлі.
- Flash:
.flv 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.
- WebM:
.webm 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.
Кодеки Відео FFmpeg – FFmpeg Video Codecs¶
These options are not available with all Containers.
- Нема Відео – No Video
Тільки для закодування аудіо.
- DNxHD
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.
- DV
Дивіться Containers.
- 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
Дивіться Containers.
- H.264
A modern variation of the MPEG-4 family, this lossy codec is very commonly used. It offers a very good compression/quality ratio.
- HuffYUV
Безвтратний кодек відео, створений Беном Рудіаком-Гоулдом – Ben Rudiak-Gould, який призначений для заміни нестисненого YCbCr як формат захвату відео.
- MPEG-1
Дивіться Containers.
- MPEG-2
Дивіться Containers.
- MPEG-4(DivX)
Inherits many of the features of MPEG-1, MPEG-2 and other related standards, but also adds new features.
- PNG
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.
- Theora
Безплатний втратний кодек відкритого стандарту розроблений разом з 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.
Кодеки Аудіо FFmpeg – FFmpeg Audio Codecs¶
- Нема Аудіо – No Audio
Лише для закодування відео.
- AAC
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.
- AC3
Audio Codec 3, технологія стиснення аудіо, розроблена Dolby Laboratories.
- FLAC
Free Lossless Audio Codec. Digital audio compressed by FLAC’s algorithm can typically be reduced to 50-60% of its original size.
- MP2
Втратний формат стиснення аудіо.
- MP3
Втратний формат стиснення аудіо, широко використовується як фінальний формат аудіо.
- Opus
Втратний формат стиснення аудіо, розроблений для закодування мовлення або загального аудіо та призначений для заміни кодека Vorbis.
- PCM
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.
- Vorbis
An open-standard, highly-compressed format comparable to MP3 or AAC. Vorbis generally achieves better sound quality than MP3 at similar bit rates.
