Thanks, I'll try that.
(Sorry Robert for the msg to your address...)
However, I don't like creating temporary files :)
Would it work if I put the sound (with a prepended AIFF header) into a NSData,
creating a movie from that (movieWithData:error:), and inserting that
movie's audio track into the "video only" movie ?
I'm really new to Cocoa and QTKit...
Thanks.

One way: Save your PCM audio to an AIF file, then open it as a QTMovie. Set the
attribute 'QTMovieEditableAttribute' to TRUE. It will just have one audio track.
Then:
QTTimeRange videoRange = QTMakeTimeRange(QTZeroTime, [videoTrkOnlyMovie
duration]);
[audioTrkOnlyMovie insertSegmentOfTrack:[videoTrkOnlyMovie firstVideoTrack] timeRange:videoRange atTime:QTZeroTime];
Then flatten it.

Hello,
I create my movie this way:
QTMovie* qtMovie = [[QTMovie alloc] initToWritableFile: path error:
&nserror];
NSDictionary* attributes = [NSDictionary dictionaryWithObjectsAndKeys:
@"mp4v", QTAddImageCodecType,
[NSNumber numberWithInt:
codecHighQuality], QTAddImageCodecQuality,
[NSNumber numberWithLong: 10000L],
QTTrackTimeScaleAttribute,
nil];
QTTime duration = QTMakeTime( 10000./mFrameRate, 10000 );
for( ""every frame"" )
{
NSImage* img = ""get the correct frame"";
[qtMovie addImage: img forDuration: duration withAttributes: attributes]
[qtMovie setCurrentTime: [qtMovie duration]];
[img release];
}
How do I add sound to the movie ?
I have the sound in memory in PCM format.
I've found how to add a sound track, but the QTTrack class has only an
addImage:... method !
Thanks.
