brew install ruby

gem install video_transcoding



# ** THE FOLLOWING ARE REQUIRED **

brew install handbrake

brew install ffmpeg

brew install mkvtoolnix

brew install mp4v2



# ** OPTIONAL **

brew install mpv

eg:

1
transcode-video --mp4 --simple --veryquick --crop detect --constrain-crop --fallback-crop handbrake --720p --add-subtitle all --output ~ -v "FIRST.mkv"
This will:
convert FIRST.mkv, output to ~
save conversion in mp4, 720p size
simple : read the instructions regarding optimization algorithm
crop : detect optimal crop, if there is a diff between handbrake & ffmpeg, choose handbrake as default
subtitles : add all subtitles from source to destination
-v : verbose output

    transcode-video

    Transcode video file or disc image directory into format and size similar to popular online downloads.

  • 1
    detect-crop

    Detect crop values for video file or disc image directory.

  • 1
    convert-video

    Convert video file from Matroska to MP4 format or from MP4 to Matroksa format without transcoding video.

  • 1
    query-handbrake-log

    Report information from HandBrake-generated

    1
    .log

    files.
