Do you need quick capture and encoding capabilities for video on your desktop? VirtualDub is a free, Open Source solution specifically designed for that purpose. VirtualDub might lack the editing power of a general-purpose editor such as Adobe Premiere, but is streamlined for fast linear operations over video in return. It has batch-processing capabilities for processing large numbers of files and can be extended with third-party video filters.
Still the best program for home video editing. Just add ffmpeg plugin from SF and you can open mp4 and other formats. The support in community is excellent. Add x264 plugin and you can save H264 (mp4, mkv, etc). I tried other applications, but I prefer VirtualDub for editing my videos (all of them are now MP4 HD videos recorded with Android smartphone or DSLR camera).
Thank you for your software. It pretty deserved his fame. Not flawless and it can do not everything but this app is very helpful from time to time.
