VirtualDub is an open source DVD/MPEG/AVI conversion and editing tool
A new version of VirtualDub has been released. Here is the change log for the new version:
New "smart rendering" feature for selective processing of video around
edit areas while copying as many existing frames as possible.
New audio waveform/spectrogram display.
Added option for preserving empty frames during recompression or
decompression instead of replicating frames.
Added option for saving raw audio stream without a header.
Added support for the Sony WAVE64 file format, for wave files larger than
Added support for reading and writing Adobe Filmstrip (.flm) files.
Added support for reading Maya IFF (.iff) files. Currently this is
limited to RGB information at 8 bits/channel.
PNG output is now supported.
Resize video filter now has options for relative and aspect-ratio derived
sizing and to save defaults.
Opening a video file from the command-line or drag-and-drop now sets the
filename as default for the Save As AVI/WAV dialogs.
Added new pitch scaling audio filter.
Improved quality of "center cut" audio filter (with suggestions from
The main window and job control dialogs now save their positions.
Opacity curves can now be attached to video filter instances.
Volume adjustment now shows amplification factor in decibels.
Filter API: Preview code preserves keyboard accelerators on preview
Job control: (X of Y) is now displayed in the job control window caption
when the job list is being processed.
AVI Info now shows additional information for PCM audio streams encoded
Capture: Added experimental option to insert arbitrary DirectShow
transform filters into a capture graph. To enable, specify the filter

Capture: Added support for switching DirectShow TV tuners between
antenna and cable modes.
The "integral conversion" option under audio conversion is no longer
Fixed a case where the projected file size status indicator could overflow
for very long audio dumps.
AVIs with MP3 audio streams where wBitsPerSample != 0 are now detected and
auto-corrected for better compatibility with the standard MP3 codec
installed in Windows.
Rewrote segmentation code to buffer data instead of attempting size
prediction; this makes the segmentation more accurate and avoids dangling
key frames during on-the-fly compression.
Added workaround for compatibility problems with Aero Glass in Windows
Vista beta 2.
Audio displacement now works when processing only part of the audio
Added warning for non-zero dwStart values in AVI files.

Changed keyboard shortcut for Undo from Ctrl+U to the standard Ctrl+Z.
Added workaround for annoying Microsoft security update that sometimes
prevents the help file from working.

Capture: Duplicate raw wave formats are no longer shown with DirectShow-
Capture: The UI now reflects changes to audio and video sources made
through the driver dialogs.
Capture: Possible fix for crash when changing formats with DirectShow-
based devices due to threading issue.
