OpenQuickTime Video Options Dialog Box (GNU/Linux)

The OpenQuickTime Video Options dialog box (titled MediaSettings) allows you to configure the video compression settings when exporting a QuickTime movie on Linux.

On GNU/Linux, Harmony uses the OpenQuickTime framework to export QuickTime movies. This framework uses its own user interfaces to allow you to configure the video and audio compression settings for a movie. Because OpenQuickTime only comes bundled with non-prorprietary codecs, its compression options are limited.

  1. Click on the Movie Options button.

    The QuickTime Movie Options dialog box appears.

  2. In the Codec drop-down, select any of the movie options.

  1. In the top menu, select File > Export > OpenGL Frames.

    The Export OpenGL Frames dialog box appears.

  2. In the Format section, select Movie.
  3. In the Movie Format drop-down, select QuickTime Movie (*.mov).

  4. Click on the Video Options button.

  1. In the Node view, locate your scene's Write node.

  1. Open the Write node's Layer Properties by doing one of the following:

    • Click on the yellow square at the left end of the Write node.

    • Right-click on the Write node, then select Layer Properties.

    The Write node's Layer Properties dialog appears.

  1. In the Write node's Layer Properties, enable the Movie option.

Parameter Description

codec

Allows you to select a video compression algorithm. By default, the following codecs are 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.
NOTE Portable Network Graphics (PNG) and Photo JPEG are the only codecs in this list that are natively supported by both Harmonyand GNOME's Totem Video Player. Other codecs may require additional software to play on GNU/Linux workstations.
quality

When using a JPEG-based codec, this allows you to 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.

fieldDominanceFor 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.
compressionThe 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.
packbitsFor movies encoded in TIFF. When enabled, this option adds extra lossless compression to the encoding.
lendianFor movies encoded in TIFF. When enabled, the video data is encoded in little endian byte order, instead of big endian.
