Version History of HandBrake 0.9.6 (x64)


-> Video:

  • updated libx264 (revision 2146)
  • MPEG-2 encoder (from libavcodec)
  • advanced options support for libavcodec encoders format: option1=value1:option2=value2

-bf 2 -trellis 2 becomes bf=2:trellis=2

-> Audio:

  • audio gain control (increase/decrease audio volume)
  • updated libogg (1.3.0) and libvorbis (aoTuV b6.03)
  • new AAC encoder (from libavcodec) (considered experimental) (supported mixdowns: Mono/Stereo/Dolby?, 5.1 will come later) (should be on par with faac in terms of quality, sometimes better)
  • FLAC encoder (16-bit, MKV container only)
  • Mac OS X: HE-AAC encoding support, via Core Audio
  • quality-based variable bitrate encoding support works with: Lame MP3, Vorbis, Core Audio AAC only implemented in CLI and Linux GUI
  • AC3 encoder: set Dolby Surround flag in stream parameters when mixdown is Dolby Surround or Pro Logic II

-> Audio Passthru:

  • DTS Passthru to MP4 container (in addition to MKV) (supported by e.g. VLC, MPlayer)
  • DTS-HD Passthru (MP4, MKV containers)
  • MP3 Passthru (MP4, MKV containers)
  • AAC Passthru (MP4, MKV containers) (known issue: Magic Cookie not passed through from MPEG Program/Transport? streams,

which will break playback in e.g. QuickTime Player)

  • Auto Passthru: one encoder, multiple codecs lets you define allowed codecs (from supported passthru codecs) lets you pick a fallback encoder if passthru is not possible


  • start MKV clusters with a video keyframe whenever possible should improve seeking and DLNA streaming
  • bug fix: use ISO 639-2 bibliographic form for MKV language codes
  • bug fix: fix crash due to division by zero in MP4 muxer
  • bug fix: fix muxing of Closed Captions. Improper interleaving broke playback on some players


-> Video:

  • updated libav* libraries from Libav ( (v0.7-1696-gcae4f4b, late October 2011) frame-based multithreading for H.264, VP8 10-bit decoding support for H.264, DNxHD Apple ProRes? decoding support
  • improved average framerate detection
  • duplicate frame detection for improved frame drop decision (CFR/PFR)
  • new Same as source, Constant Framerate option for devices that don't support variable framerate automatically picks a constant framerate closest to the detected average framerate
  • bug fix: fix problem when resolution changes in the middle of a video stream

-> Audio:

  • Blu-ray: make TrueHD, DTS-HD and E-AC3 Secondary Audio streams available for decoding and/or passthrough
  • bug fix: libavcodec-decoded streams can now be decoded multiple times

  • bug fix: fix audio screech at beginning of some audio tracks when decoding AC3
  • bug fix: fix DTS decoder audio volume (was too low)

  • improved MPEG Program/Transport? stream support support for MPEG-1 Program streams support for HD-DVD EVOB streams improved handling of Transport streams that have no PCR
  • WTV container support (via libavformat)
  • bug fix: files with more than 20 tracks (video, audio, subtitles etc.) are now supported
  • bug fix: some QuickTime MOV files were misdirected as MPEG Transport streams
  • bug fix: fix detection of TrueType? font attachments that don't have the correct MIME type


  • new, much improved decomb filter (but slower) new settings are default old settings become decomb "Fast"
