VirtualDub Portable is the popular video capture/processing utility packaged as a portable application, so you can take your images with you and do your editing on the go.

VirtualDub Portable is a video capture/processing utility. 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.

What's New in version 1.8.5:

[bugs fixed]

• Capture: Fixed a possible crash when loading device settings.

[regressions fixed]

• Video filters which used GDI rendering in in-place mode but only requested a DC for one buffer now work.

What's New in version 1.8.6 Build 30009:

[bugs fixed]:

• Wheel scrolling in the Set Text Information dialog closes the edit control.
• Save Segmented AVI now works with VBR audio.
• Animated GIF export now fails with an error if the current output format is compressed or otherwise not supported.
• JobControl: Fixed crash when one machine attempts to run a job in distributed mode right when another machine deletes it.
• JobControl: The filter crop mode saved in jobs was opposite from selected. (This only affected YCbCr cropping.)
• Capture: Fixed crash when capture driver sends audio samples when DirectShow graph is not running.
• D3D: Fixed sporadic crash on lost device.
• D3D: Fixed Direct3D errors when display debug information is enabled and a video filter fails to initialize.
• Frameserver: Frame rate adjustments weren't always propagated correctly.

[regressions fixed]:

• Fixed crash when using fast/normal recompress mode without a video codec.
• Fixed divide by zero crash when loading video and a video filter in the list is unable to initialize.
• Changing the "source rate adjustment" option no longer invalidates the current selection.
• Rendering would loop endlessly if an error occurred during video compression and threaded compression was disabled.
• Disabling the "directly decode YCbCr formats" option works again.
• Filters: lMicrosecsPerFrame and lMicrosecsPerSrcFrame were reporting milliseconds (broken since 1.8.0).
• JobControl: Fixed case where a non-distributed "load job list" command can fail due to erroneously running distributed-mode code.
• JobControl: Fixed problem where dialog would suddenly close when editing job names.
• Script: Fixed crash when removing video filter from filter chain.
• DV: Audio decoding works again with NTSC DV files (broken since 1.8.4).
