What's new in this version:

[features added]

    * Added support for YV12 during fast recompress.
    * Input video is now displayed during fast recompress for UYVY and YUY2 modes.
    * Video display updates are now suppressed for panes that are totally hidden.

[bugs fixed]

    * MP3 rate correction was correcting dwRate but not interleaving, causing some problems for embedded decoders. The interleaving rate is now adjusted on the fly. Note that MP3 correction is still not enabled when segmentation is active.
    * Time base for the position control was improperly affected by the "convert to fps" option.
    * "Box blur" filter was broken on CPUs without MMX. (Dumb compiler bugs....)

[regressions fixed]

    * Menu cleanup: removed synchronous blit and histogram, fixed vertical layout and pane swap.
    * Fixed crash when loading some job configurations from 1.5.4 and below.
    * Fixed audio displacement not working in simple audio pipeline with forward offset.
    * Adjusted Z-order of status bar relative to panes.
    * MPEG-1 decoding was broken on platforms with MMX but without SSE2.
    * Plugin code could crash if no plugins were installed, particularly under Windows NT 4.0.
    * Video codec code occasionally named the wrong codec when reporting video format corruption during codec arbitration.
    * Corrected DCT coefficient pruning in MJPEG decoder.
    * Fixed crash when WAV open fails.
    * Delete was producing invalid subsets in some cases.

[features added]

    * Partial Unicode support -- you can now open and save files using Unicode filenames.
    * "Chroma smoother" video filter refilters point-sampled chroma with linear interpolation.
    * Single-stream cut & paste. (Be patient....)
    * Improved performance of AVI parser, particularly for Direct mode streaming.
    * Improved performance of bicubic upsampler.
    * Audio filter graph now shows intermediate audio formats on connections.
    * Audio filters can now be plugins.

    * Log windows now have a context menu for clearing, copying, and saving the log text.
    * Modified AVI2 indexing to relax indexing restrictions somewhat, although it's still not user configurable yet.

[bugs fixed]

    * Hex editor occasionally displayed the wrong data after a find or save command.
    * "Attach extension" option didn't work for signpost save dialog.
    * Fixed crash when I/O errors occur during a processing operation, and then occur again when attempting to gracefully finalize the partial output file.
    * "Clear" didn't work in audio filter graph.
    * Fixed I/O errors when attempting to push audio forward with advanced audio filtering enabled.
    * "Go to" command didn't handle timestamps with frac- tional seconds that only had 1 or 2 decimal digits.
    * "General convolution" generated bad code for factors of 2, 4, and 8 when dynamic compilation was enabled.
    * Interleave periods of zero are no longer allowed.
    * Added workaround for crash or hang when compressing with the "3ivx D4 4.0.4" video codec.
    * Fixed non-interleaved save mode and made it cooperate with segmentation.
    * Added workaround for heap corruption when processing audio in advanced mode sourced from some versions of Avisynth.
    * Clarified DivX warning to note that it doesn't apply to the DivX 4+ codecs.
    * Fixed filter cropping not working properly when "motion blur" was the first filter in the chain.

[bugs fixed]

    * Fixed race condition in processing pipeline shutdown that was more likely to occur in Windows 95/98.
    * Key frame markers were getting written on some drop frames when upsampling the video stream.
    * MPEG code was issuing warnings whenever decode time- stamps were more than 0.62s apart; this has been fixed to use the actual spec limit of 0.7s.
    * Operation couldn't be aborted while B-frame lag frames were being flushed at the end.
    * Fixed a bad error message that displayed a bogus filename.

What's new in this version:

[features added]

    * Can add a single job to the batch list with syntax: /p[input_file],[output_file]
    * Filters are now loaded and unloaded on the fly to circumvent TLS (thread local storage) selector limits.
    * Cropping bounds can now be dragged via the mouse.
    * Improved, friendlier crash diagnostics.
    * Basic audio filter support (no plugin support yet, though). The pitch shifter sucks.
    * Increased accuracy of audio/video timing by switching from microsecond to rational calculations.
    * Changed font on dialogs to enable ClearType on XP.

[features removed]

    * Deleted outdated 3x3 average filter -- it has been superceded by "blur."

[bug fixes]

    * New MPEG audio core (Priss) -- fixes decoding errors in layer I and layer III audio and adds SSE polyphase support.
    * Fixed motion JPEG decoding bugs when padding is present before markers.
    * Fixed crash in SSE2 code when decoding MPEG-1 file odd width in macroblocks.
    * Fixed crash in SSE2 resize routine when doing 4-tap vertical resample with odd width.
    * Fixed swapped UVs in About dialog box. ^^;
    * Fixed sync errors in MPEG-1 playback when decoding an audio stream which flips the copyright bit between frames or switches layer III bitrates (VBR).
    * Fixed "Frame not found" errors in MPEG-1 decoder when GOP is longer than 128 frames.
    * Rewrote resampler clip determination code again. Hopefully this one will be Bug Free (tm).

What's new in this version:

[features added]

    * Added frequently-requested Lanzcos3 kernel to resize filter. Can't see any difference whatsoever.

[bug fixes]

    * Fixed nasty resize filter bug and RGB24<->RGB32 conversion errors on odd bitmap widths. (Regressions in 1.4.12)
    * Fixed audio desynchronization when processing compressed audio in direct stream copy mode with both a start offset and deleted segments. Thanks to Cyrius for the bug report and fix.
    * Audio compression system now drops a final partial block from an audio codec -- Microsoft ADPCM was producing these, resulting in a runt AVI stream sample. The new behavior matches that of Sound Recorder.
    * A partial final block no longer triggers the VBR audio adjustment routine.
    * "Previous keyframe" from beyond the end no longer seeks to start if frames have been deleted or masked. Also thanks to Cyrius.
    * Fixed crash in MPEG-1 decoder when playing or saving a video stream with D-frames or invalid frame types.

    * WAV writer now writes out the required 'fact' chunk for compressed WAVs.
    * Filter preview dialog now sanely reports errors in a non-ugly font.
