Version History of VirtualDub 1.5.5 [features added]
Partial Unicode support -- you can now open and save
files using Unicode filenames.
\"Chroma smoother\" video filter refilters point-sampled
chroma with linear interpolation.
Single-stream cut & paste. (Be patient....)
Improved performance of AVI parser, particularly for
Direct mode streaming.
Improved performance of bicubic upsampler.
Audio filter graph now shows intermediate audio
formats on connections.
Audio filters can now be plugins.
New MPEG-1 video core (Meia) -- full vertical
clipping. Horizontal clipping is still by macroblock.
Rewrote display code -- DirectDraw support is now
automatic.
Log windows now have a context menu for clearing,
copying, and saving the log text.
Modified AVI2 indexing to relax indexing restrictions
somewhat, although it\'s still not user configurable
yet.
[bugs fixed]
Hex editor occasionally displayed the wrong data after
a find or save command.
\"Attach extension\" option didn\'t work for signpost
save dialog.
Fixed crash when I/O errors occur during a processing
operation, and then occur again when attempting to
gracefully finalize the partial output file.
\"Clear\" didn\'t work in audio filter graph.
Fixed I/O errors when attempting to push audio forward
with advanced audio filtering enabled.
\"Go to\" command didn\'t handle timestamps with frac-
tional seconds that only had 1 or 2 decimal digits.
\"General convolution\" generated bad code for factors
of 2, 4, and 8 when dynamic compilation was enabled.
Interleave periods of zero are no longer allowed.
Added workaround for crash or hang when compressing
with the \"3ivx D4 4.0.4\" video codec.
Fixed non-interleaved save mode and made it cooperate
with segmentation.
Added workaround for heap corruption when processing
audio in advanced mode sourced from some versions of
Avisynth.
Clarified DivX warning to note that it doesn\'t apply
to the DivX 4+ codecs.
Fixed filter cropping not working properly when
\"motion blur\" was the first filter in the chain.
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.
