Avidemux v2.5.0 (SVN-r5031) | 9.72 Mb

What the heck is Avidemux?

Imagine an application which does everything VirtualDub can do, but runs on various platforms, supports a lot of containers, comes with all Codecs you need built-in and doesn´t use the nasty VfW interface. That applications is Avidemux! And now the “official” version: Avidemux is a free video editor designed for simple cutting, filtering and encoding tasks. It´s graphical user interface looks pretty similar to VirtualDub and most features known from VirtualDub are available too. Avidemux natively supports a great number of file types, such as AVI, MPEG, VOB, TS, MP4, ASF, OGM, MKV and FLV. At the same time Avidemux natively supports a wide range of Video/Audio formats, including MPEG-1, MPEG-2, MPEG-4 ASP, H.264/AVC, DV, HuffYUV, MP3, AAC, AC-3 and Vorbis. Tasks can be automated using projects, job queue and powerful scripting capabilities. Video-DVD or (S)VCD compliant streams can be created with easy-to-use “Auto” wizards. Multi-threading is supported!

What encoders are supported by Avidemux?

Avidemux comes with several video encoders built-in: Xvid (MPEG-4 ASP), x264 (H.264 aka AVC), libavcodec (MPEG-4 ASP, MPEG-2, MPEG-1, FLV, HuffYUV, FFV1, MJPEG, H.263, DV) and mpeg2enc (MPEG-1, MPEG-2). Also it includes various audio encoders: LAME (MP3), FAAC (LC-AAC), Aften (AC3), Ogg Vorbis and TwoLAME (MP2). Please note that Avidemux does not support the platform-specific and outdated ´Video for Windows´ (VfW) interface and it never will! This means there is absolutely no way to use DivX (or any other VfW-based Codecs) with Avidemux! But don´t worry: Avidemux will open all files, that were encoded with DivX, just fine. Avidemux simply uses it´s own (internal) MPEG-4 decoder instead of the proprietary DivX decoder. Furthermore the files encoded with Avidemux and Xvid will play 100% fine on a “DivX certified” player, as long as you use the appropriate encoder settings…

What video filters are supported by Avidemux?

Avidemux comes with a wide range of video filters built-in. Most of those filters were ported from MPlayer, VirtaulDub or Avisynth. There are filters for Cropping, Resizing (Bilinear, Bicubic and Lanczos) and Expanding. For processing of interlaced video, there are various Deinterlacing and IVTC filters (e.g. Yadif, TDeint, Kernel Deinterlacer, Smart Deinterlace, mcDeinterlace, DGBob and Decomb Telecide). Furthermore there are filters for Denoising (FluxSmooth, denoise3d/hqdn3d, Stabilize, Temporal Cleaner, etc.), Sharpening (MSharpen, asharp, etc.), Color Correction and many more. Last but not least there is a new plugin system for ´external´ video filters now. So you can add additional filters to Avidemux without re-compiling!
