OpenQuickTime Video Options Dialog Box

The OpenQuickTime Video Options dialog box is used to configure the video 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 .
Parameter Description

Codec

Lets you select a codec. By default, the following codecs will be available:

  • Motion-JPEG A: A very portable codec that performs lossy JPEG compression and interlaces the frames. Motion-JPEG A compression is less efficient than Photo JPEG in terms of quality and file size, but may be a more portable alternative for software that does not support Photo JPEG.
  • Photo JPEG: Encodes the movie as a sequence of JPEG images. JPEG images have lossy compression. This is the most efficient codec for file size.
  • Portable Network Graphics (PNG): Encodes the movie as a sequence of PNG images. PNG images have lossless compression.
  • Tag Image File Format (TIFF): Encodes the movie as a sequence of uncompressed TIFF images. This codec is lossless.
  • Uncompressed (RGB): Encodes the movie as uncompressed bitmap data. This codec is lossless.
Quality

For JPEG-type codecs, lets you set the JPEG compression quality. By default, this will be set to 85. Possible values range from 0 to 100. The higher the quality, the more disk space the resulting video file will take.

fieldDominance For codecs with interlacing. This is set to 1 by default. If set to 1, the first field will be encoded on odd frames, and the second field will be encoded on even frames. If set to 2, the first field will be encoded on even frames, and the second field will be encoded on odd frames.
compression The amount of lossless compression to perform when exporting in PNG format. PNG compression is lossless, but higher compression settings will take longer to encode and decode.
packbits For TIFF movies, this option adds extra lossless compression to the encoding.
lendian Encodes data in little endian byte order, instead of big endian.
