Video Transcoding v0.20.0 Release Notes

  • Monday, June 18, 2018

    • ✅ Now require HandBrakeCLI version 1.0.0 or later. Not only does this change make for easier testing, but it allows removal of many capability-detection hacks needed to support older versions. My thanks again to all the users who provided positive feedback about this online!
    • ⏪ Relax frame rate control in transcode-video so that the options --rate=30 and --pfr are no longer passed to HandBrakeCLI for most non-DVD videos. This means that the peak frame rate will no longer be limited to 30 FPS, allowing camera-generated videos to retain their original frame rates. However, the old behavior can be restored for those videos by adding --limit-rate 30 to your transcode-video command line.
    • 0️⃣ Modify transcode-video to no longer pass --encoder-preset=medium to HandBrakeCLI since that's the default behavior anyway. However, adding --preset medium to your transcode-video command line still does so.
    • Modify transcode-video to no longer pass a named audio encoder to HandBrakeCLI in order to select AAC, i.e. ca_aac or av_aac, since AAC is the default audio format anyway. However, adding the --aac-encoder option to your transcode-video command line still allows an explicit choice.
    • 👍 Modify transcode-video to substitute "analyse" for the x264 option called "partitions" when invoked with the --quick or --veryquick options. This is done to better match the archaic internal name used by HandBrake. It has no effect on actual transcoding behavior.
    • ➕ Add -n as a shortcut alias for the --dry-run option in transcode-video. This is the same shortcut alias used in rsync and make.
    • 0️⃣ Expand the "Explanation" section of the "README" document to describe both the special, or default, ratecontrol system and the average bitrate (ABR) ratecontrol system, enabled via the --abr option.
    • ➕ Add clarification to the "README" document that stereo AAC tracks can also include surround audio information in matrix-encoded Dolby Pro Logic II format.
    • 🛠 Fix spelling of "suppress" in the --help output of query-handbrake-log. Thanks, @chrisridd! Via #205.
