It also plays on iPhones. It also plays on AppleTVs. It should also play just about anywhere else, hence the name. It is full anamorphic DVD resolution--no tricks with downscaling like stuff from the iTunes Store. It includes chapters, and has the first audio track in both AAC (DPL2 downmixed) and AC3 pass-thru, just like the AppleTV preset. In fact, it should give the same quality as the AppleTV preset, but faster...and at a larger file size. Like the AppleTV preset, it used CRF, so sizes will vary. + +0.9.3 Snapshot2 -> 0.9.3 Snapshot 3 (r1797) +Core Library: +- Universal input support, utilizing libavcodec from the FFmpeg project for decoding non-MPEG-2 video +- Newer, faster, better version of the x264 codec, including psychovisual optimizations +- Better AV sync through full compliance with the MPEG Standard Target Decoder timing model +- More accurate auto-cropping +- Support for New Zealand and Norwegian HDTV broadcasts (H.264 and AAC-LATM in MPEG-TS) +- Detelecine is now "VFR detelecine" by default, dropping some frames and extending others to make up lost time, old behavior of keeping duplicate frames is enabled by selecting a framerate besides "Same as source" +- Threaded deinterlacing in Slow and Slower modes +- Threaded and entirely rewritten decomb filter +- Better audio resampling interpolator +- Better gamma in QuickTime through the use of the COLR MP4 atom +- Better constant quality encoding when using FFmpeg +- Hopefully better cache and virtual memory performance by recycling buffers that were most recently used instead of least +- Fix for MP4s with "negative duration" errors. +- Set the detelecine filter to work better with PAL by using "loose" breaks +- Fix for missing initial H.264 NAL units, improves reliability of 8x8dct +- Fix for subtitle-scan with XviD encoding +- Fix for crash at the end of 2nd pass using x264 +- Deblock filter works now +- Rewritten update system, so the core library can read a portion of Sparkle appcasts. +- Updates for libsamplerate, libogg, xvidcore, libtheora, libmpeg2, lame, faac, and of course ffmpeg and x264. + +Mac GUI +- Entirely rewritten and far more flexible queue that can be saved between sessions, capable of preserving queued items after a crash +- Now requires vlc 0.9.xx to read protected dvd's in the users /Applications folder +- Fix for 4x3 loose anamorphic to keep it from downscaling +- Countless other improvements + +Windows GUI +- Resolution calculation +- Better preset bar +- Better queue (including queue recovery feature) +- Better activity log window +- Improved UI (layout changes, animated x264 options, DVD drive detection, duration displayed) +- More options - includes support for custom auto name format & starting the CLI minimized +- Countless other improvements + +Linux GUI (GTK) +- It's alive! + +Known Issues in Snapshot 3 +- Possibility of a flickering line at the top or bottom of the frame after Slow or Slower deinterlacing or decombing +- Input bitrate display may be off by a factor of 100 for H.264-in-TS sources +- Constant Quality Rate preset probably needs a lower quality level (60% - 55%) +- With non-DVD sources that don't have AC3 audio, you can't encode 1 input audio track to multiple output audio tracks +- Slow and Slower deinterlacing and decombing are BROKEN in Windows +- QuickTime won't read Xvid-in-MP4 output, although VLC will +- Windows GUI does not detect all audio tracks from non-DVD sources + +0.9.3 Snapshot 1 -> 0.9.3 Snapshot 2 (r1477) +Core Library: +- Anamorphic PAR for the AVI container +- Allow constant frame rates when they different from the source's frame rate (otherwise pass through the variable MPEG-2 frame durations ) +- Decomb filter (selectively deinterlaces when it sees interlacing in the frame) +- Filter bug fixed, that would skip any filters after detelecine, if VFR wasn't enabled +- Loose anamorphic + FFmpeg video bug fixed + +Windows GUI: +- Title dropdown list bug fixed +- Missing log file bug fixed + +CLI: +- Default audio samplerate changed to 48kHz, audio bitrate changed to 160kbps. +- Samplerate entry bug fixed + +0.9.2 -> 0.9.3 Snapshot 1 (r1457) +Core Library: +- New audio subsystem (no more AAC+AC3, control each track's codec and settings individually) +- Removed libdvdcss (HandBrake no longer decrypts DVDs on its own, will use VLC to do so if it's available) +- Added Theora encoder +- Fixed x264-in-avi and ffmpeg-in-avi +- Fixed xvid +- More accurate scaling +- Major sync improvements +- Major stream improvements +- AAC+AC3 support in MKV +- MKV seeking fixes +- Make sure subtitles get displayed long enough to read them +- Updated VBV 2-pass and VBV 1-pass patch for x264 +- Adaptive Quantization for x264 +- Recover from bad preview scans +- Recover from invalid PGNs +- Fixed vorbis bitrate control +- Snapshot builds + +Mac: +- New audio interface +- Loads libdvdcss from VLC at runtime if it's present on the user's system +- No more general-purpose "Codecs" menu -- set video and audio codecs individually +- More robust preset system, in preparation for nested presets +- Made 64-bit MP4 file widget more prominent +- Only allow useful x264 options in the advanced tab +- Various fixes and improvements + +Windows: +- New x264 tab +- New audio interface +- Various fixes and improvements + +CLI: +- New audio interface + Changes between 0.9.1 and 0.9.2: CORE |
