OpenQuickTime Sound Options Dialog Box

The OpenQuickTime Video Options dialog box is used to configure the audio compression settings when exporting a QuickTime movie file on Linux.

On Windows and macOS, Harmony uses Apple QuickTime to export QuickTime movies, and hence uses QuickTime's interface to configure video and audio compression settings for exporting movies. Since QuickTime is not supported on GNU/Linux, Harmony uses the OpenQuickTime library to create QuickTime-compatible movie files, which have a more limited set of compression settings.

NOTE: For tasks related to this dialog box, see Exporting a Movie File on page 1.
Parameter Description

Codec

  • IMA 4:1: This codec compresses audio data to require a quarter of the disk space required for uncompressed audio data. It is not supported by a lot of software.
  • Twos Complement - Little Endian PCM: A standard uncompressed audio codec.
  • Twos Complement - Big Endian PCM: A legacy standard uncompressed audio codec. This codec may be compatible with older editing interfaces.
  • (mu)-Law 2:1: Similarly to A-Law, this codec uses logarithms to compress audio data. The resulting audio stream requires half the disk space of uncompressed audio data, but is of noticeably lower quality.
