Avidemux is a freeware, open-source video editor designed for multi-purpose video editing, converting, simple cutting, resizing, filtering, and encoding tasks.

It helps many file varieties, together with AVI, MP4, Matroska, MPEG-2, H.264, and H.265. It doesn’t but, or solely partially helps trendy open codecs, like Opus, WebM, VP8, VP9, and AV1. Tasks will be automated utilizing initiatives, job queues, and highly effective scripting capabilities.

Avidemux lets you edit most video files by your necessity to make them play on any chosen machine. Multi-threading is supported! The graphical person interface of Avidemux seems to be fairly much like VirtualDub. Most options recognized from VirtualDub can be found too and natively help nice file varieties, akin to AVI, MKV, MPEG, VOB, MP4, TS, ASF, OGM, and FLV.

Avidemux can not open uncooked MPEG streams. Instead, it may open listed MPEG streams. The index is a textual content file containing navigation info. It is required to permit body accuracy.
As for MPEG streams, a NuppelVideo file has no inner index. Avidemux will rebuild it routinely upon loading (that might take some minutes).

Avidemux also can open a stream of uncompressed BMP files (RGB) or a set of JPEG files or a set of PNG files. The newest version of Avidemux can often decode the WMV/ASF containers, there are often some files that also have issues with opening or taking part. If you will have that drawback, then you’ll be able to attempt to place the WMV contents into an AVI container.


Multithreading has been applied within the following areas of Avidemux (some partially by libavcodec):
