VirtualDub 1.9.11

(2010.12.24)

Changes in 1.9.11 Build 32842

[bugs fixed]
* Filters: Added compatibility option for filters that rely on constant buffer addresses.

32-bit
This is the current release of VirtualDub for end users, containing the executable and supporting files. Unzip the contents into a new folder and run VirtualDub.exe. (Do not run it directly from the zip file!)

Requirements: Microsoft Windows 98, ME, NT4, 2000, XP, Vista, Server, or newer; 80486 or higher CPU; 16MB of memory. This version will run on both x86 (32-bit) and x64 (64-bit) versions of Windows. Sorry, but there is no native version for Mac OS X or Linux.

Antivirus software issue: Some versions of McAfee Antivirus have a bug where they report a Dialer-182 spyware infection after running VirtualDub 1.8.x. This is a false alarm caused by an exceptionally poor Registry key matching pattern in McAfee (anything in Software\Freeware) which misdetects VirtualDub's stored settings as from a dialer. VirtualDub does not have any malicious code or any dialer logic. Unfortunately, I cannot force McAfee to fix their software. If you are having problems with this, you may need to use 1.9.1+, which has the settings Registry key changed to work around this problem.

64-bit
This version is compiled specifically for CPUs that support AMD64/x64 long mode, including AMD Athlon 64, AMD Athlon X2, AMD Opteron, Intel Xeon CPUs with EM64-T, and Intel Core i7 CPUs. You must have the x64 Extended (64-bit) version of Windows to run the 64-bit version of VirtualDub. You cannot run this version on a 32-bit version of Windows even if your CPU is 64-bit capable.

It is recommended that you use the 32-bit version unless you have a specific need for 64-bit execution, as the 64-bit version cannot use 32-bit codecs or plugins.

VirtualDub 1.9.9

(2010.04.09)

Changes in 1.9.9 Build 32817

[features added]
* The log now indicates which plugins failed to load on startup.

[bugs fixed]
* UI: Fixed a case where the output pane could change aspect ratio when auto pane sizing was enabled and the main frame window was resized.

* UI: The output pane now has the correct pixel aspect ratio when an input plugin indicates non-square pixels and no filters are used.

* UI: 6% zoom menu items didn't display checkmarks properly.

* AVI: Fixed incorrect decoding of paletted video files when biClrUsed=0 in the header and the input color mode is set to Autoselect.

* AMD64: Fixed incorrect disassembler module in crash handler.

* Render: Fixed sporadic hang when using smart rendering with fast recompress mode.

* Render: Audio is no longer cut off when "cut off when video ends" option is disabled and IVTC filter is used.

* Filters: Fixed duplicate frame fetches when using lagged filters (ex: temporal smoother) at the very end of the source video stream.

* Filters: Fixed frame fetch errors when using filters with a frame window (ex: interpolate) at the end of an MPEG-1 video.

* Filters: Source length was not set during renders.

* Filters: Fixed garbage line at bottom of frame when using IVTC filter with an odd height.

* Filters: Fixed bug where filter preview stopped displaying frames past a certain point when edits had occurred on the timeline.

* Batch: Timeline had wrong frame counts when creating batch jobs via Process Directory or Batch Wizard with a frame rate changing filter (ex: IVTC).

* Decoders: Fixed decoding of Huffyuv files using median prediction and 4:2:0 encoding.

* Decoders: Fixed incorrect chroma DC handling with restart markers in MJPEG decoder.

VirtualDub 1.9.8

(2009.12.24)

Changes in 1.9.8
Build 32706 (1.9.8, stable)

[bugs fixed]
* Fixed occasional hang with certain conversion paths from 8-bit (256 color) to YCbCr formats.
* Fixed bug where two curve points on top of each other in the curve editor didn't save properly in script files.
* Fixed decompression error in IFF ANIM decoder when entire bitplanes were skipped.
* Filters: Fixed glitches in IVTC pattern in the first five frames of video.
* Filters: Fixed occasional crash when 3D acceleration is enabled and the 3D device is lost.
* Filters: Fixed bugs where the curve display would either show the wrong frames or fail to step in certain circumstances.
* Filters: Blends are no longer allowed on filters where the input and output have different formats; this didn't work and produced a corrupted image.
* Filters: Fixed crash in smoother filter with MMX disabled.
* Decoders: Fixed crash in Motion JPEG decoder on certain kinds of corrupt data.
* Frameserver: Fixed random crash issue related to stream format structure.
* Hex editor: Fixed bug where 'O' and 'S' activated open and save commands instead of Ctrl+O and Ctrl+S.

VirtualDub 1.9.7

(2009.10.18)

Changes in 1.9.7
Build 32661 (1.9.7, stable)
[bugs fixed]
* 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.

[regressions fixed]
* Filters: Fixed filter errors not showing up properly.
* Filters: Fixed crash when PNG decoding error occurs with logo filter.
* Filters: Fixed random crash when opening Video Filters dialog before opening any videos.

* Filters: Shift+Mouse color checking in preview windows works again (broken in 1.9.2).
* Filters: Fixed incorrect frame being sampled after edits were done on the timeline.
* UI: Removed "run as job" check box from Save Image Sequence dialog, since it's now redundant with the "queue batch operation" command.
