video processing and capture
Download from PortableApps.com
VirtualDub Portable can run from a cloud folder, external drive, or local folder without installing into Windows. It's even better with the PortableApps.com Platform for easy installs and automatic updates.
VirtualDub Portable is a video capture/processing utility. It lacks the editing power of a general-purpose editor such as Adobe Premiere, but is streamlined for fast linear operations over video. It has batch-processing capabilities for processing large numbers of files and can be extended with third-party video filters. VirtualDub is mainly geared toward processing AVI files, although it can read (not write) MPEG-1 and also handle sets of BMP images. Both the 32-bit and 64-bit versions of VirtualDub are included and the correct one is automatically used for your current machine to ensure best performance.
Additional Codecs Note: VirtualDub uses a combination of plugins for codecs (see above) and codecs on the local machine, so if you wish to use a non-standard codec like DivX or XVID, you'll need it installed. This is unavoidable at the moment.
