Configuring Movie Settings for QuickTime Movies on GNU/Linux
- Open the Video Options dialog.
- In the Video Options dialog, select the preferred Codec:
- 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.
- If exporting in Motion-JPEG A or Photo JPEG, set the desired JPEG quality for your video in the Quality field. This setting ranges from 0 to 100, and is set to 85 by default. A higher setting increases picture quality, but makes the resulting movie file heavier.
- If exporting in Motion-JPEG A, set the desired Field Dominance. Motion-JPEG A is interlaced. When set to 1, odd frames are encoded on the first field. When set to 2, odd frames are encoded on the second field.
- Click OK.
- Open the Sound Options dialog.
- In the Sound Options dialog, select the preferred Codec:
- A-Law 2:1: 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.
- 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.
- In the Sample Rate drop down menu, select 22050. This is the only sample rate supported for movie export in Harmony on Linux.
- Click OK.
