If the information in the “Decoder” section says “built-in”, it means a decoder for the format is included in the Avidemux source code and you have nothing to install. If the decoder is not built-in, Avidemux can optionally use an external decoder for the format, if it was compiled with support for it. text/html 2012-11-11T08:51:40+02:00 https://www.avidemux.org/admWiki/doku.php?id=general:audio_encoders&rev=1352620300&do=diff Audio encoders In the open source world, several audio codecs are available. For creating AVI files, the general practice rule is to use the LAME MP3 encoder. The reason being is that it is very high quality and is widely supported by nearly every video player. If you are concerned about patent issues on MP3 format or want audio of even higher accoustic quality, choose Vorbis instead. text/html 2012-11-11T08:51:40+02:00 https://www.avidemux.org/admWiki/doku.php?id=general:bugtracker&rev=1352620300&do=diff Reporting bugs Please report bugs in the Avidemux forums to get some feedback and determine the nature of the problem.

It is considered to be “state of the art” in general audio coding and the successor of MP3. Compared to MP3, AAC provides higher quality music with approximately 30% less storage space or bandwidth. AAC provides up to 48 full-bandwidth audio channels with sample rates up to 96(nbsp)kHz, plus 15 low frequency (limited to 120(nbs… text/html 2012-11-11T08:51:40+02:00 https://www.avidemux.org/admWiki/doku.php?id=general:input_formats&rev=1352620300&do=diff Supported input formats Format Restriction AVI None, multiple audio tracks supported text/html 2012-11-11T08:51:40+02:00 https://www.avidemux.org/admWiki/doku.php?id=general:output_formats&rev=1352620300&do=diff Supported output formats Format Filename extension Note AVI .avi Audio Video Interleave.

If the “Built-in” column says Yes, it means a copy of the encoder is included in the Avidemux source code and you have nothing to install. If it says No, Avidemux has to be compiled with support for that encoder (which must be installed on your system).

Xvid was started by a group of volunteer programmers after the OpenDivX source was closed in July 2001. Xvid features MPEG-4 Advanced Simple Profile features such as B-frames, quarter pixel motion compensation, global motion compensation, lumi masking, trellis quantization, and H.263, MPEG and custom quantization matrices.
