Avidemux is a free video editor designed for simple cutting, filtering, and encoding tasks.

VirtualDub can run on most platforms, supports many containers, comes with all Codecs you need built-in, and doesn´t use the nasty VfW interface.

Avidemux is designed for simple cutting, filtering, and encoding tasks, and it also supports multi-threading. Its graphical user interface looks pretty similar to VirtualDub, and most features recognizable from VirtualDub are available. Avidemux natively supports many file types, such as AVI, MPEG, VOB, TS, MP4, ASF, OGM, MKV, and FLV.

At the same time, Avidemux natively supports a varied 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 queues, and powerful scripting capabilities. You can create Video-DVD or (S)VCD compliant streams utilizing the easy-to-use "Auto" wizards.
