Avidemux, a free video editor designed for simple cutting, filtering, and encoding tasks that supports many file types including AVI, DVD, MP4, and ASF, is now at version 2.6.8.Avidemux is a project that has been around for a long time and the software has been evolving slowly with the rest of the world. Even if it's no longer a cutting-edge application, it's still one of the best video editing programs available for the Linux platform.
The app can be used to perform various tasks that range from simple video cutting to video conversion and everything else in between. Even if it's called Avidemux, it's also perfectly capable to manipulate audio files and perform various actions specific to that format.
Avidemux 2.6.8 features support for the following formats: AVI, OpenDML, MPEG, ASF, NuppelVideo, Images (BMP, JPEG, etc.), H.263(+), MPEG-4, QuickTime, 3GP, MP4, OGM, Matroska, and Flash Video.
The changes included in the latest Avidemux 2.6.8 are numerous and a lot of them are quite important. For example, initialization of Qz for JPEG export is now done properly, an override menu has been implemented to force the language, support has been added for os.environ, a crash that occurred when having an audio problem has been fixed, mp4v2 has been added to installer files again (it was removed in a previous release), and the channel mapping is now working correctly when the source is only mono.
Also, the encoding for codecs that are not supporting planar (MP2) has been fixed, when the user is importing MP2 audio it's no longer detected as MP3, deleting chunks of the video is no longer leading to seeking errors, a limited form of copy/paste support for the editor has been added, and an issue that occurred when the source had more than 4 tracks has been fixed.
A number of smaller fixes have been implemented. According to the changelog, the detection of double fps input files is now a lot better, the eac3 probe is now using brute force, TS/Demux no longer drops audio, the management of PCM audio has been fixed, the re-indexing of Mpeg2 files in MKV is now working properly, the fast start mode has been added again, libass has been updated, and a few performance improvements have been added for avsfilte.
A complete list of changes can be found in the official announcement. Keep in mind that the software is available on multiple platforms. You can download Avidemux 2.6.8 right now from Softpedia.
