What's new in this version:
[features added]
* Capture mode can now apply filters against I420/IYUV video.
* Capture: "Start on click" added.
* Capture: File autoincrement added.
* Crash disassembler has now been totally rewritten; now supports all IA-32 instructions through Pentium 4 and Athlon.
* Special support added for DivX 5.x B-frame mode. NOTE: Interleaving may be a little funny.
[bugs fixed]
* Volume adjustments were active during input preview.
* dwSampleSize was being copied from source video streams even if it was incorrect.
* AVI2 output code was crashing if the source video stream dwSampleSize!=0 and no audio was attached.
* Confirmation dialog for "Reset video stream" didn't have a cancel button. ^^;;
* Several places were using signed division for frame rate fractions -- fixes "can't initialize timer" errors.

What's new in this version:
[features added]
* Capture: Added wraparound workaround for 2^31 us (35m) wrap as well as 2^32 us (71m) timing wrap.
* Added more verbose error messages.
* Added some PIII instructions to crash disassembler.
[bug fixes]
* Fixed scanline alignment and invalid format errors in image source reader.
* Fixed Ctrl-W shortcut for "Close AVI."
* Fixed title bar not being correct after exiting capture mode [regression in 1.4.8].
* Temporal smoother now initializes its window from the first frame it receives rather than to black.
* IVTC no longer drops last 8 or so frames when no audio is present.
* Fixed deadlock on MP3 audio codecs that report a codec delay of 0 (LameACM).
* Fixed sfence-related crash and decompression errors in MJPEG decoder [regression in 1.4.8].
* Fast recompress no longer aligns frame subsets to keyframe boundaries.
* "Scan for bad frames" would sometimes not mark the correct frames.
* Scene scan sometimes wouldn't display the frame it had stopped on.
* Fixed line of green pixels on right side of frame when using 3x3 TV filter.

What's new in this version:
[features added]
* Motion JPEG decoder has improved heuristics for field order determination, support for restart markers, and supports 4:4:4 as well as 4:2:0 and standard 4:2:2.
* An error is now thrown if a third-party driver leaves the CPU in MMX state when returning, which previously could cause floating-point code to malfunction.
* Added workaround for ASUS ASV1 driver crashing under Windows NT platforms.
* MPEG-1 files with small amounts of junk at the beginning are now recognized.
* BMP image sequences can now be loaded as well as saved.
* Frame rate changes are reflected in the timestamp panel.
* Hex Editor no longer locks files and can highlight important fields in AVI files.
* Capture: Luma squish now supports UYVY in addition to YUY2.
* AVI handler can now recover OpenDML segments from truncated files and has more aggressive recovery methods.
* AVI handler recognizes 'bt20' as a format that does not have delta frames.
* Added workaround for audio sync problems caused by malformed AVI files with VBR MP3 audio.
* Support for masking video frames and for autoscanning the video stream for bad frames to mask.
[bug fixes]
* No more crashing when attempting to do certain kinds of seeks with no video loaded.
* Capture: Noise reduction works properly with cropping.
* Fixed MPEG-1 frame order bug in frameserver that was also introduced in 1.4.6.
* Fixed MPEG-to-AVI conversion resulting in trashed wPriority and wLanguage fields in the stream header.
* Capture: Under Windows 98/2000, monitor and system power down are inhibited in capture mode.
* Fixed scripts and job entries being trashed when the generated script exceeds 16K.
* Fixed codec issues caused by script system not handling long strings produced from codec data. Thanks to the DivX 4 team for reporting this one.
* IVTC no longer causes bitrates for CBR video codecs to drop by 20%%.
* Fixed output files being generated with type 'ivas' when the source was a type-1 DV file.
* Fixed diagonal stripe or crash with MMX version of Levels filter when input bitmap is an odd width.
* Fixed AVI streaming routines going off the deep end when encountering garbage data in the AVI stream.
* Fixed occasional corrupted frames when playing back AVI with "drop frames when behind" enabled.
* IVTC now forces interleaving on a 4-frame basis like it's supposed to.
* The audio compression dialog was passing bad precision values to audio codecs and only querying for real-time compression.
* Corrected crashes or errors on uncompressed video streams that have a zero or incorrect biSizeImage field.
* Capture: Multisegment and info panel settings saved correctly.
* Capture: Compatibility mode capture prohibited when multisegment capture enabled.

What's new in this version:
[bugs fixed]
* Quick preview didn't work if the current position was past the number of source frames, even if the timeline was longer than that.
* Added FPU guards that were missing in a couple of critical places (AVIFile open, codec negotation).
* The timeline wasn't properly extended if segments were auto-attached by filename after edits had been made.
* Configuration scripts saved when no file is open no longer alter the edit list when loaded.
* Jobs launched from the command line used the normal error modes rather than those set as default by the user.
[regressions fixed]
* Filter preview buttons weren't updating the frame.
* Save Image Sequence command would randomly produce an unrequested job instead of initiating the render directly.
* Append AVI function was incrementing the filename extension instead of the name component.
* Avisynth scripts smaller than 60 bytes weren't being autodetected properly.
* MP3 audio streams were getting written with dwLength=0 if correction was enabled.
* MPEG decoder occasionally decoded garbage into the video frame, resulting in sporadic block errors during processing.

What's new in this version:
[features added]
* Enhanced error concealment in MPEG-1 video decoder to reduce picture spew on errors (NOT THE PARSER).
* "Drop frames when behind" can now drop frames before the decoder. This helps with Huffyuv playback.
* Capture-mode noise reduction now works with UYVY video as well.
[bug fixes]
* Fixed that blasted Audio Interleaving bug I introduced in V1.4.5.
* Added sample skip support for audio converter and amplifier filters, to prevent long delays when using subsets with them.
* 'Save WAV' now truncates the file if the file you're saving over is bigger than the new data it's being replaced with.
* Fixed frame output display not updating when attempting to display same frame after changing filters.
* Fixed audio interleaving dropping out after a preview.
* Read errors no longer appear interactively, blocking batch operations.
* Attempting to shift in capture mode from 'preview with histogram' to overlay mode no longer switches to preview mode instead.
* Fixed problem with hardware accelerated preview in capture mode with some ATI video cards.
* No more of "1057%% complete" in Job Control.
* Changed some of the more embarrassingly bad error messages.
