What's new in this version:

[features added]

    * Added an option in Options > Preferences > AVI to force sector alignment for large uncompressed frames. This can resolve compatibility problems with some uncompressed hardware video playback units.

[bugs fixed]

    * Capture: Video/audio format and compression and video frame rate now autosave on disconnect.
    * Capture: Fixed some cases where the Raw Audio Format dialog didn't highlight the currently selected PCM format.
    * Capture: Noise reduction threshold was not restored properly.
    * Capture: Renamed Peak Meter back to Volume Meter and restored V accelerator.
    * Frame byte size was being computed improperly for YCbCr AVIs.
    * Fixed broken MJPEG video decoding at bottom-right corner on streams that have restart markers.
    * Reworked MJPEG field ordering detection to be consistent with DirectShow MJPEG decoder. If this is reversed for your files, enable "swap fields" in AVI extended open options.
    * Scene detection was busted for 16-bit RGB (very rare case).
    * Minor status updating features, such as the current position nub moving during input preview, were broken after running a job that ended in an error.
    * (AMD64 only) Scene detection is now implemented.
    * (AMD64 only) Enabled some video filters that had scalar implementations: flipv, fliph, deinterlace, rotate, and HSV.
    * Save Image Sequence dialog didn't show the "add as job" button as checked, even if it was saved as such from the last time.
    * Fixed minor bugs in various image converters and improved accuracy of a few YCbCr-to-RGB converters.
    * Fixed UYVY/YUY2-to-RGB converters not interpolating chroma properly.
    * Fixed YVU9 chroma planes being swapped on write to disk and enabled YVU9 for direct input.

[regressions fixed]

    * App would sometimes exit after stopping frameserver.
    * Frameserver sent garbage data if the video filter chain changed the frame size.
    * Fixed a regression in video codec negotiation for MS MPEG-4 V3 variants where a different but compatible codec was not properly detected.
    * Doing a paste with no selection caused one frame to be deleted before doing the paste.
    * Write open failures were being reported again when the target file couldn't be opened a second time in fast I/O mode, which happens sometimes with emulators or remote drives. The slower fallback has been reinstated.
    * Running out of disk space at the very end of a render operation was sometimes reported as an I/O error rather than a write error.
    * Sampling in filter preview could fail if the timeline had been edited.

    * Capture: Audio device was not auto-saved.
    * Capture: Fixed crash when attempting to capture with an unsupported video format (MPEG-1/2, interleaved DV, etc.).
    * MPEG-1 video decoder occasionally glitched due to a missing end tag.
    * Removed dumb debug code that was causing a "???" message box to appear when unrecognized command-line flags are seen.
    * Fixed display panes not always updating properly.
    * Fixed rare crash if an MPEG-1 open failed extremely early.
    * Fixed cases where the render start/end point wasn't updated properly when a selection bound was used to "push" the other, i.e. "set end" before start, or vice versa.

    * Fixed massive slowdown in hex editor when scanning RIFF tree for an AVI file with a lot of video frames.
    * Fixed bug with the "last frame" facility in the video filter system that was causing the motion blur filter to fail if it was first and another filter followed it.
    * Fixed intermittent crash under Windows 98 when repainting draggable video frame.

[features added]

    * Rewrote command line parsing so that arguments to /s, /p, and /b no longer require the parameters to be adjacent to the switch.
    * New /i (invoke) command line flag runs a script and passes additional parameters to it, which are available as VirtualDub.params[n].
    * Unescaped, native-coded strings can now be embedded in a script using U"..." syntax. In particular, this allows filenames to be inserted directly from a batch file.
    * The Abort button on the dub status dialog now confirms by default for non-preview operations; this can be disabled in Preferences.

What's new in this version:

[features added]

    * Native AMD64 build (see Release Notes for restrictions).
    * New "perspective" video filter can deproject subimages that are displayed obliquely in a scene.
    * YUV formats can now be directly selected for decompression and compression.
    * Planar YUV formats are now supported for both display and output.
    * Added preliminary DirectX 9 (D3D9) display driver support, with support for filter mode selection and multipass bicubic filtering. This driver must be manually enabled in Preferences.
    * Added OpenGL display driver, with support for filter mode selection. This driver must be manually enabled in Preferences.
    * Frame seeking is now incremental so that extremely long frame distances between key frames no longer hang the app during the preload.
    * Added support for the PRELOAD flag on video decompression to speed up seeking.
    * New position slider that displays frame number markers and supports mouse wheel scrolling beyond 32K.
    * Fast recompress format is reported in log.
    * Basic movement keyboard shortcuts now work in filter preview.
    * JPEG image sequence input and output is now supported.
    * Single images can be opened as video files.

[optimizations]

    * Major optimizations to Resize video filter.
    * SSE2-optimized IDCT kernel.

[workarounds]

    * Added workaround for codecs that pass decode queries for formats they can't actually decode. VirtualDub will only use these codecs to decode formats with FOURCCs that the codec is registered with, or that the codec naturally produces.
    * Improved workaround for codecs that unmask FPU exceptions in their DLL initialization, particularly FP Divide by Zero (which can cause other codecs to crash).

[bugs fixed]

    * Expanded a number of internal variables to 64-bit to reduce problems with long streams that have more than 2^31 bytes or samples.
    * Fixed crash when opening file for first time with output pane disabled.

    * Corrected asymmetry in response of TV filter in 5x5 chroma blur + tsoften mode.
    * A low frame rate video with no audio could cause the blitter thread to consume 100%% CPU at high priority, virtually locking the system.
    * Enabling error concealment prevented the bad video frame scan from working.
    * Fixed crash when changing priority in the middle of render termination.
    * Fixed 3072 sample delay in "center cut" audio filter.
    * Aggressive AVI recovery was very slow when processing large blocks of invalid data, such as 8MB of nulls.
    * Fixed leak of handles in frameclient driver that was causing Windows XP Explorer to keep AVI files open frameclient proxy mode was enabled.
    * Jobs using WAV file audio didn't close the WAV file after completion, keeping it locked across subsequent jobs.
    * Appended file lists were being written out in job scripts in ANSI rather than UTF-8, causing problems with high-plane characters.
    * Audio information in File Information wasn't taking all samples into account.
    * Long paths in the most recently used (MRU) list now ellipsize.
    * Lowered priority of livelock messages to Info so they don't flag as warnings in the job queue.
    * Fixed race condition that sometimes resulted in final B frames not being flushed completely.
    * "Butterfly" audio filter didn't work with 8-bit audio.
    * Unbuffered I/O is now disabled on non-hard-disk paths for better efficiency on slow links, particularly over networks.
    * Frameserver paths longer than 64 bytes prevented the frameclient from connecting properly.
