Download VirtualDub 1.7.1 experimental

Avery Lee today released a new version of the experimental 1.7 branch. With this program video can be recorded and edited (capture and processing). It doesn’t really have a proper editor, but is more intended to be used in conjunction with programs such as Adobe Premiere. It is made for editing avi files but is also capable of opening mpeg and bmp files. The changelog for this release shows the following changes:

Features added:

• AVI file info now shows the FOURCC of the video stream.
• The “display decompressed output” option can now be enabled and disabled in the middle of encoding.
• Improved playback timing.
• Added /hexview command-line flag to open a file in read-only mode.
• Added /noStupidAntiDebugChecks for development purposes.
• Added “warp resize” video filter.
• The “resize” video filter now allows editing the frame height with an aspect ratio constraint active.
• Ctrl+Drag in the audio display modifies the audio displacement.
• Added an option to create several types of diagnostic test videos.
• Added Y800 as a synonym for Y8.
• Added support for the 4:4:4 planar YCbCr “YV24” format.
• Added animated GIF import.
• D3D: UYVY, YUY2, YV24, YV16, YV12, I420, and YVU9 video display is now accelerated in Direct3D mode.
• D3DFX: Added additional support for field-based display shaders.
• Capture: Added a new screen capture driver.
• Capture: Added configurable hotkeys for stopping and starting capture.
• Capture: DirectShow filter graph build errors are now noted in the log window.
• Capture: Full-screen mode now auto-hides mouse cursor.
• Capture: Added UI for modifying DirectShow brightness, contrast, gamma, sharpness, and hue settings.
• Capture: Audio playback setting is now auto-saved.

Bug fixed:

• “Export as filmstrip” command failed if no audio stream was available.
• Filmstrips didn’t resave properly as AVI (video stream type set incorrectly).
• Modified the SSE check to ignore the flush-to-zero (FTZ) bit, which unfortunately some compiler DLL runtimes twiddle.
• “Preserve empty frames” was writing out the empty frames as key frames. VirtualDub corrects this on load, but it was still incorrect on disk.
• “Preserve empty frames” caused the video codec key frame interval to work incorrectly — it counted compressed frames rather than total frames.
• “Display decompressed output” was broken.
• Added workaround for silent crash when using the audio display with older versions of Avisynth.
• Added workaround for digital cameras that leave the last byte off of JPEG images.
• Added workaround for some naughty DLLs that prevented VirtualDub’s crash logging mechanisms from working properly.
• Added more workarounds for overlay surface goofiness on Windows Vista.
• Audio display now reflects timeline edits and the audio displacement setting.
• Made it more difficult to accidentally select frames in the audio display.
• Fixed divide by zero crash when D3DFX display is enabled and a video pane is shrunken to zero width.
• Fixed case where tiny audio chunks were emitted periodically when using some MP3 codecs at a 44KHz sampling rate (audio interleaving issue, not sync issue).
• Fixed goofed file filters in source dialog of “create paletted AVI” option.
• Inverse telecine could be enabled with smart rendering (which doesn’t work).
• Fixed “preserve empty frames” and “smart rendering” options to work better in the presence of a B-frame encoding delay.
• Capture: Alt+Enter full-screen toggle left window in topmost placement.
• Capture: Fixed sporadic crash when capturing with resync disabled.
• Capture: Fixed tabbing in “set custom format” dialog.
• Capture: /capfileinc and the startup code didn’t increment the filename properly past existing files when multisegment capture was enabled.
• Capture: Hide on Capture now works for DirectShow-based devices.
• Capture: Added workaround for driver bug in Adaptec AVC-1400 GameBridge drivers that causes a crash when displaying video capture pin properties.
• Capture: Fixed filter leak in DirectShow driver in some cases when the filter graph failed to build properly.
• Capture: When the “transform filter” registry option was used, the transform filter popped off the capture filter after a video format change.

Regressions fixed:

• Fixed crash when opening AVI file with truncated MP3 audio format.
• Fixed some audio sync errors when cutting.
• Fixed the resize filter’s settings not saving properly. This was actually caused by a long standing overload resolution bug in filter script with multiple glue functions on the same overload.
• Fixed crash when attempting to preview with an audio stream for which no decompressor is available.
• Fixed crash when using quick preview beyond end of selection.
• Fixed a couple of cases of bogus total audio sample counts being reported in the dub status window.
• Audio sync sometimes wasn’t correct when cutting files with VBR audio.
• Audio stream estimate on status window was sometimes negative.
• Fixed crash at end of operation with IVTC enabled.
