VirtualDub is a video capture / processing utility for 32-bit Windows platforms, 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. 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 1.9.8:

• Fixed occasional hang with certain conversion paths from 8-bit (256 color) to YCbCr formats.
• Fixed bug where two curve points on top of each other in the curve editor didn't save properly in script files.
• Fixed decompression error in IFF ANIM decoder when entire bitplanes were skipped.
• Filters: Fixed glitches in IVTC pattern in the first five frames of video.
• Filters: Fixed occasional crash when 3D acceleration is enabled and the 3D device is lost.
• Filters: Fixed bugs where the curve display would either show the wrong frames or fail to step in certain circumstances.
• Filters: Blends are no longer allowed on filters where the input and output have different formats; this didn't work and produced a corrupted image.
• Filters: Fixed crash in smoother filter with MMX disabled.
• Decoders: Fixed crash in Motion JPEG decoder on certain kinds of corrupt data.
• Frameserver: Fixed random crash issue related to stream format structure.
• Hex editor: Fixed bug where 'O' and 'S' activated open and save commands instead of Ctrl+O and Ctrl+S.
