Version History of VirtualDub 1.6.6 [features added]
Added an option in Options > Preferences > AVI to force sector alignment for large uncompressed frames. This can resolve compatibility problems with some uncompressed hardware video playback units.
[bugs fixed]
Capture: Video/audio format and compression and video frame rate now autosave on disconnect.
Capture: Fixed some cases where the Raw Audio Format dialog didn\'t highlight the currently selected PCM format.
Capture: Noise reduction threshold was not restored properly.
Capture: Renamed Peak Meter back to Volume Meter and restored V accelerator.
Frame byte size was being computed improperly for YCbCr AVIs.
Fixed broken MJPEG video decoding at bottom-right corner on streams that have restart markers.
Reworked MJPEG field ordering detection to be consistent with DirectShow MJPEG decoder. If this is reversed for your files, enable \"swap fields\" in AVI extended open options.
Scene detection was busted for 16-bit RGB (very rare case).
Minor status updating features, such as the current position nub moving during input preview, were broken after running a job that ended in an error.
(AMD64 only) Scene detection is now implemented.
(AMD64 only) Enabled some video filters that had scalar implementations: flipv, fliph, deinterlace, rotate, and HSV.
Save Image Sequence dialog didn\'t show the \"add as job\" button as checked, even if it was saved as such from the last time.
Fixed minor bugs in various image converters and improved accuracy of a few YCbCr-to-RGB converters.
Fixed UYVY/YUY2-to-RGB converters not interpolating chroma properly.
Fixed YVU9 chroma planes being swapped on write to disk and enabled YVU9 for direct input.
[regressions fixed]
App would sometimes exit after stopping frameserver.
Frameserver sent garbage data if the video filter chain changed the frame size.
Fixed a regression in video codec negotiation for MS MPEG-4 V3 variants where a different but compatible codec was not properly detected.
Doing a paste with no selection caused one frame to be deleted before doing the paste.
Write open failures were being reported again when the target file couldn\'t be opened a second time in fast I/O mode, which happens sometimes with emulators or remote drives. The slower fallback has been reinstated.
Running out of disk space at the very end of a render operation was sometimes reported as an I/O error rather than a write error.
Sampling in filter preview could fail if the timeline had been edited.
About:
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.
An exciting history of VirtualDub startup can be found here.
