Op de website van het populaire video-capturing en -bewerk tooltje VirtualDub lezen we het heugelijke bericht dat versie 1.5.0 van het programma zijn weg naar het internet heeft gevonden. Het GPL-licenced stukje software mist het een en ander aan features ten opzichte van bijvoorbeeld Adobe Premiere maar blinkt uit in snelheid en stroomlijn. In versie 1.5.0 zitten op het eerste gezicht minder veranderingen dan je zou denken bij zo'n grote sprong in versienummer. Schijn bedriegt echter, de hele code is namelijk herschreven. Er zijn ook wat features toegevoegd, zo is er nu bijvoorbeeld een bescheiden mogelijkheid tot audiobewerking. Het complete changelog voor 1.5.0 build 15584 ziet er zo uit:
[features added][features removed]
- Can add a single job to the batch list with syntax: /p[input_file],[output_file]
- Filters are now loaded and unloaded on the fly to circumvent TLS (thread local storage) selector limits.
- Cropping bounds can now be dragged via the mouse.
- Improved, friendlier crash diagnostics.
- Basic audio filter support (no plugin support yet, though). The pitch shifter sucks.
- Increased accuracy of audio/video timing by switching from microsecond to rational calculations.
- Changed font on dialogs to enable ClearType on XP.
[bug fixes]
- Deleted outdated 3x3 average filter -- it has been superceded by "blur."

- New MPEG audio core (Priss) -- fixes decoding errors in layer I and layer III audio and adds SSE polyphase support.
- Fixed motion JPEG decoding bugs when padding is present before markers.
- Fixed crash in SSE2 code when decoding MPEG-1 file odd width in macroblocks.
- Fixed crash in SSE2 resize routine when doing 4-tap vertical resample with odd width.
- Fixed swapped UVs in About dialog box. ^^;
- Fixed sync errors in MPEG-1 playback when decoding an audio stream which flips the copyright bit between frames or switches layer III bitrates (VBR).
- Fixed "Frame not found" errors in MPEG-1 decoder when GOP is longer than 128 frames.
- Rewrote resampler clip determination code again. Hopefully this one will be Bug Free (tm).
- Fixed spurious errors at end of operation when saving WAV file.
- Outputted configuration files and job scripts now include the correct audio filename when a .wav file is selected through a script.
- Fixed AVI segmented output creating short files when working from MPEG-1 source or when IVTC is active.
- Image import filter wasn't caching frames.
- Fixed a couple of Get*() script calls that were declared incorrectly internally and didn't work (thanks to Cyrius).
- Blur filter now handles cropping properly.
