QuickTime issues
In order to import/export QuickTime files in SONAR, you must install both the filters AND QuickTime.
Below are some other known QuickTime issues:
• It is presently only possible to export QuickTime videos on a 32-bit system. This is a limitation of
QuickTime, not SONAR.
• QuickTime Import/Export requires version 6.5.1 or higher of the QuickTime Player to be installed.
The QuickTime Player is not included with SONAR, but can be downloaded separately from
Apple's web site (www.apple.com/quicktime/download/win.html).
• Audio mixdown to QuickTime must be set to 16 bits stereo or mono, or the resulting export will
create a unusable file or abort with an error.
• Audio mixdown to QuickTime must be set to 48 KHz or less or the resulting export will create a file
that plays back incorrectly.
• When exporting to QuickTime, the frame rate of the QuickTime video compressor will default to
“best possible”. Since not all movies in a SONAR video project correctly report their frame rate,
the best practice is manually enter the desired frame rate. This is done in the video settings of the
QuickTime video compressor.
• Exports to QuickTime from a SONAR video project created from an AVI using the Indeo video
compressor will create a movie with white frames.
• Exports to QuickTime may have an extra white frame on the last frame of the movie. This extra
frame can be removed with the QuickTime Pro Player or another QuickTime editing application.
