VirtualDub 1.9.7 Build 32661

VirtualDub 1.9.7 Build 32661 is designed as a professional video capture/processing utility for 32-bit and 64-bit Windows platforms (98/ME/NT4/2000/XP/Vista/7), 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.

Major Features:

1. VirtualDub helps you get video into your computer: If your capture device is Video for Windows compatible, then VirtualDub can capture video with it.  But VirtualDub isn't your average capture program:
   
   • Fractional frame rates.  Don't settle for 29 or 30 when you want 29.97.
   • Optimized disk access for more consistent hard disk usage.
   • Create AVI2 (OpenDML) files to break the AVI 2GB barrier and multiple files to break the FAT32 4GB limit.
   • Integrated volume meter and histogram for input level monitoring.
   • Real-time downsizing, noise reduction, and field swapping.
   • Verbose monitoring, including compression levels, CPU usage, and free disk space.
   • Access hidden video formats your capture card may support but not have a setting for, such as 352x480.
   • Keyboard and mouse shortcuts for faster operation.  To capture, just hit F6.
   • Clean interface layout: caption, menu bar, info panel, status bar.
2. VirtualDub lets you clean up video on your computer: There are lots of programs that let you "edit" video.  And yet, they're frustratingly complex for some of the simplest tasks.  VirtualDub isn't an editor application; it's a pre- and post-processor that works as a valuable companion to one:
   
   • Reads and writes AVI2 (OpenDML) and multi-segment AVI clips.
   • Integrated MPEG-1 and Motion-JPEG decoders.
   • Remove and replace audio tracks without touching the video.
   • Extensive video filter set, including blur, sharpen, emboss, smooth, 3x3 convolution, flip, resize rotate, brightness/contrast, levels, deinterlace, and threshold.
   • Bilinear and bicubic resampling -- no blocky resizes or rotates here.
   • Decompress and recompress both audio and video.
   • Remove segments of a video clip and save the rest, without recompressing.
   • Adjust frame rate, decimate frames, and 3:2 pulldown removal.
   • Preview the results, with live audio.
   • You can take a captured clip, trim the ends, clean up some of the noise, convert it to the proper frame size, and write out a better one.  Don't see a video filter you want?  Write your own, with the filter SDK.
3. VirtualDub is fast.
   • The author of VirtualDub is very impatient.  That means his program is designed for speed, both in the interface and in the processing pipeline.  Converting a compressed, 320x240 MPEG-1 file to an uncompressed, 24-bit AVI requires only these two steps in VirtualDub:
   • Open video file (Ctrl-O).
   • Save AVI (F7).

Enhancements:

• AVI: Modified indexing traversal to handle deeply nested hierarchical indices.
• Filters: Rescaling after changes to filter chain now extends or trims ending ranges as needed to match changes to frame count.
• Filters: Fixed bug where a filter capable of both 3D accelerated and unaccelerated modes (resize) could force a conversion to YV24 at its  input when RGB32 was a better match.
• Filters: Filter preview no longer always runs the filter chain with the input video mode set to default.
• Display: Added workaround for video card/driver combos that perform extremely poorly with DirectDraw/Direct3D blits overlapping a secondary monitor. This can be toggled in Options > Preferences > Display.
• Command line: The warning dialog at the end of command line processing is now suppressed if /x is specified.
