Complete Version history / Release notes / Changelog / What's New for MPEG4 Modifier
1.4.6 (2015-Jan-10):
Marked as system DPI aware to fix blurry UI with high DPI settings.
Changed license to MIT (was GPL v2).
1.4.5 (2012-Sep-02):
Ability to export custom quantization matrix to .cqm file.
Fixed window layout with high DPI settings.
Supports loading on .NET 4.x runtime (not required; still 2.0 compatible).
1.4.4 (2007-Jan-13):
* Fixed a few small issues that prevented DivX subtitles from working.
* Added *.divx to the supported extension list in the file dialogs.
* A default file name is now provided when saving.
1.4.3 (2006-Nov-05):
* Doesn't remove delay frames anymore, this caused synch problems with joined videos.
* FourCC and user data information are now shown in the "Video Info" text.
* It's now possible to pack videos containing drop frames.
1.4.2 (2006-Sep-16):
* Fixed several problems with OpenDML reading/writing (writing bad OpenDML index entries, out of memory exception or unnecessary reading when loading, incomplete loading of files with damaged/missing index).
1.4.1 (2006-Aug-04):
* Fixed some problems with packing which also required corrections to the timestamp calculation code.
* If you try to load a non-MPEG4 video, the error message now displays which codec the file uses.
* Better default directories for load/save file dialogs.
1.4.0 (2006-Aug-03):
* AVI handling code completely rewritten, supports OpenDML and incomplete files (rebuilds the index including keyframe flags).
* Ability to add/readd packed bitstream.
* Optimized some parts, runs significantly faster.
* Added Cancel button on load/save progress window.
* Doesn't freeze explorer while loading a file after dropping onto the source textbox.
* Updated code to take advantage of C# 2.0 features, and lots of cleanup.
1.3.4 (2005-Dec-14):
* Re-added support for files with packed bitstream containing real N-VOPs (apparently the XviD 1.1 betas do this)
1.3.3 (2005-Dec-11):
* Fixed bug when unpacking files with missing N-VOPs (caused by cutting/joining)
* Removed support for files with packed bitstream containing real N-VOPs to simplify code
1.3.2 (2005-Mar-08):
* New feature: Video Info now shows how many warp points are actually used (for example, DivX indicates 2 warp points in the VOL, but the 2nd one is never used)
* Added detection for corrupt RIFF chunk sizes
* Fixed byte order problem in AVI index on big endian systems (for command line unpacker running on OS X)
1.3.1 (2005-Jan-06):
* Added percent in titlebar of progress window
* Added 1.85:1 display aspect ratio
* Fixed saving AVIs with no index
* Fixed small cosmetic issues in main window
1.3.0 (2004-Dec-20):
* New feature: option to automatically change user data when unpacking
* Fixed bugs with 'rec ' list indexing
* Added progress bar during load and save
* A file can be loaded from the command line, or by dropping it on the AVI Source text box
* Error checking is less strict (no more "No dummy N-VOP found for packed frame" and "Invalid VOL" errors)
* Files are closed sooner, and output file is deleted if an error occurs during save
* Other code improvements and clean-up
1.2.0 (2004-Sep-14):
* New feature: modification of field order for interlaced videos
* New feature: video information (i.e. whether or not QPel/GMC were used, stats for how many I/B/P/S/N-VOPs were used, list of VOP type and timestamp for each frame, etc.)
* Packed bitstream removal can now tell the difference between dummy N-VOPs and real N-VOPs (though I'm told no encoder currently writes real N-VOPs in a packed bitstream)
1.1.0 (2004-Jun-24):
* New feature: packed bitstream removal
* New feature: userdata modification
* Recognizes frames written in '00db' chunks
1.0.0 (2004-Jun-14):
* Has a proper GUI
* Warns if the AVI is OpenDML
* Reads the frame width/height from the video (for DAR->PAR calculation)
* Writes dwSuggestedBufferSize in the video stream header (it wrote 0 before)
* Supports 'rec ' lists
* Code has been restructured
