Download VirtualDub 1.5.5

The development of VirtualDub, a program with which you can edit video files, is in full swing. A new version has recently become available that has been labeled 1.5.5 and experimental. A completely new setup has been chosen in which DirectDraw is chosen as the default as display code. Furthermore, the developer tells a whole story about the P4 version that is no longer offered from now on. The changelog looks like this:

VirtualDub 1.5.5 is out on SourceForge and is the first version that I’ve explicitly tagged as “experimental.” The primary reason is the new display code — 1.5.5 is the first version to use DirectDraw by default, the result of which is a significant increase in rendering speed as well as a usable stretch. (Right-click the panes for the new options.) 1.5.4 is pretty stable at this point and as such it’s a good idea to split versions into stable and development releases. So please try 1.5.5 and report the problems, and if you have problems, use 1.5.4. 1.5.5 does add a few more workarounds for various problems as well as some optimizations for direct stream copy mode, so if all goes well it should work better than 1.5.4.

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.

bug 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 fractional 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.
