VirtualDub is a video capture/processing utility for 32-bit Windows platforms (98/NT/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.

Build 16296 (Version 1.5.4):

[features added]

  • * Added workaround for infinite B-frame delay
    interaction with DivX 5.0.5 Pro.
  • * File information for AVI files now shows estimated
    bitrate.

[bugs fixed]

  • * Fixed race condition in processing pipeline shutdown
    that was more likely to occur in Windows 95/98.
  • * Key frame markers were getting written on some drop
    frames when upsampling the video stream.
  • * MPEG code was issuing warnings whenever decode time-
    stamps were more than 0.62s apart; this has been
    fixed to use the actual spec limit of 0.7s.
  • * Operation couldn’t be aborted while B-frame lag
    frames were being flushed at the end.
  • * Fixed a bad error message that displayed a bogus
    filename.
