-
- [optimizations]

- to disk (i.e. faster).

- [Features added]
- * Job system.
- * Scripting support.
- * Double-clicking a filter in 'Add Filter' adds it.
- * New 16-bit dithering option dithers 24-bit images down
- to 16-bit 5:5:5 RGB -- the difference is noticeable
- sometimes.
- * Drop Frames During Preview option.
- * Sync to Audio now adjusts the time base rather than
- throttling the output, leading to smoother playback.
- * MPEG requester displays progress in bytes.
- * Audio support for MPEG files using Tomislav Uzelac's
- Amp 0.7.6 engine.
-
- [optimizations]
- * Bicubic resizes optimized for MMX.
- * MPEG decoding much faster (by about 50%), and MMX
- optimized.
- * 16-bit RGB MPEG decoding.
-
- [bug fixes]
- * Audio streams are no longer written out with overly
- large wave formats when in Full Processing Mode. This
- caused RealEncoder G2 beta 2 to reject PCM audio
- streams from VirtualDub.
- * Fixed a really stupid error: the bicubic resizer won't
- crash on integral multiples anymore.
- * The bilinear/bicubic resize filters have been adjusted
- to better filter when enlarging by an integral factor.
- * Scene Thresholds don't reset when the CPU Preferences
- tab is visited.
- * A race condition during dub shutdown has been fixed.
- * Crash/hang problems with certain size MPEG chunks
- solved.
- * MRUList fixed -- VirtualDub runs under NT again!
- * Predicted size and audio size in status box fixed.
- * Closed a lot of memory leaks, including one caused by
- a buggy CreateDIBSection() under NT4.0.
-
- Build 3174 (Public Release 3):
- [Features added]
- * Striped AVI output mode for higher performance and
- evading the 2Gb limit.
- * Scene forward/reverse.
- * Histogram works on cards with hardware decompression.
- * VCM frameclient driver + support; now XingMPEG Encoder
- can use frameservers.
- * MPEGs can have their P/B frames omitted and/or motion
- vectors truncated to full pels for performance.
- * AVI rekeying, to fix AVIs with bad keyframe flags.
- * Task priority and filename extension behavior
- configurable.
- * Resize filter can now do bicubic filtering in addition
- to bilinear (formerly Linear Interpolation).
- * Flip Horizontally filter.
- * Limit preferences saving.
- * Color can be set for the fill filter.
- * MMX and FPU settings have been moved to Preferences,
- where they can be saved.
- * Double-clicking on a filter entry brings up the
- configure dialog box for that filter.
-
- [bug fixes]
- * Frameserver setup no longer says 'Korin.'
- * AVI output routines fixed - no longer writes odd-byte
- chunks.
- * Potential crash/hang problems with y-values in the
- fill filter fixed.
- * Filter entries now highlighted after an Add.
-
- Build 2769 (Public Release 2):
- [Features added - main program]
- * Preliminary MPEG support (video only).
- * Histogram support. Click on the histograms to cycle
- between R/G/B/I modes.
- * Dubbing and capture windows now show filename.
- * Support for compressed 8-bit AVI files.
- * Audio compression and decompression.
- * Left, right arrow keys fine-step frames.
- * New output mode: individual DIB frames.
- * Context help for all capture and some dub dialogs.
- * Frameserver mode, to serve processed video output to
- other applications in real-time.
- * Vertical flip filter.
- * MRU (Most recently used) list.
- * Interleaving options now work.
-
- [Features added - capture]
- * Capture mode now has accelerators.
- * Total size during internal capture.
- * Histogram works on capture cards that use hardware
- compression.
- * Capture file, driver, and settings can be saved.
-
- [optimizations]
- * Larger granularity for index blocks.
- * Resize filter heavily optimized for FPU - linear
- interpolation now runs at full speed on many AVIs,
- without an MMX CPU.
- * Slightly better interface performance under NT.
- * Output buffering works now.
- * Internal capture mode - much better capture
- performance.
-
- [bug fixes]
- * Output file properly closed upon write failures.
- * Audio offset/clipping parameters fixed for frame rate
- decimation.
- * WAV files now closed when disabled.
- * Time limit for captures fixed; no longer alters the
- audio buffer size.
- * Conversion routines fixed for odd AVI widths; solves
- crash problems on many AVIs, particularly in 16-bit
- decompression mode.
- * ICDecompress() now used with decompressors that do
- not support ICDecompressEx(). This allows the
- miroVideo DRX MJPEG decompressor to work with
- VirtualDub.
- * Titlebars no longer refreshed every 1/2 second
- unless necessary -- speeds up dubs on slow systems.
- * Problems with audio-less files fixed.
- * Fixed range dialog from 'locking' when length(ms)
- field cleared.
- * Dynamic compilation filters work under NT.
- * Fixed corruption/crash problems with convolution
- based filters.
- * Failed captures and dubs are still finalized.
- * Memory leaks with filter system solved.
- * Capture errors forced to foreground.
-
- Build 1482 (Public Release 1):
- * Marking works.
- * Frame reset to 0 upon load.
- * Position control.
- * Rounding/overflow errors in clipping dialog gone.
- * 8-bit AVIs now supported.
- * End-of-file race condition fixed.
- * AVI length write fixed
- (NOTE: If you have files which give errors at the end
- of processing, trim the end back and turn on
- Audio clipping.)
- * Audio interleaving fixed.
- * Preview mode audio playback no longer cut off.
- * Miscellaneous bug fixes.
