VirtualDub is a video capture/processing utility for 32-bit Windows platforms (95/98/ME/NT4/2000/XP), licensed under the GNU General Public License (GPL). 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.

[bugs fixed]

• Improved accuracy of "set so audio and video durations match" for short clips.
• Fixed vertical chroma positioning errors when converting to 4:2:0 or 4:1:0 YCbCr.
• PluginSDK: Direct stream copy from a plugin audio stream caused dwStreamSize in the AVI to be set incorrectly.
• PluginSDK: Fixed crash when using plugin to load a file with an audio stream that isn't AVI compatible.
• Capture: When "wait for OK" was enabled with a DirectShow driver, time spent in the dialog was counted against a time stop condition.
• Capture: Fixed crash when an error occurs while starting capture with a custom hotkey.

[regressions fixed]

• "Save segmented AVI" no longer crashes when only video is enabled.
• Prohibit zero for frame rate adjustment.
• Filters: The error return from runProc is ignored again for compatibility with earlier versions of VirtualDub; this fixes some video filters that broke in the 1.7.x series.
• D3D: Fixed a display change related crash.
