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. It is mainly geared toward processing AVI files, although it can read MPEG-1 and also handle sets of BMP images.

What's New in version 1.9.7:

[bugs fixed]
AVI: Modified indexing traversal to handle deeply nested hierarchical indices.
Filters: Rescaling after changes to filter chain now extends or trims ending ranges as needed to match changes to frame count.
Filters: Fixed bug where a filter capable of both 3D accelerated and unaccelerated modes (resize) could force a conversion to YV24 at its input when RGB32 was a better match.
Filters: Filter preview no longer always runs the filter chain with the input video mode set to default.
Display: Added workaround for video card/driver combos that perform extremely poorly with DirectDraw/Direct3D blits overlapping a secondary monitor. This can be toggled in Options > Preferences > Display.
Command line: The warning dialog at the end of command line processing is now suppressed if /x is specified.

[regressions fixed]
Filters: Fixed filter errors not showing up properly.
Filters: Fixed crash when PNG decoding error occurs with logo filter.
Filters: Fixed random crash when opening Video Filters dialog before opening any videos.
