I should have been clear about my question. Sorry about that. The
problem I am having is that when the resulting movie is saved it has a
duration of 0 and not even the first frame shows. So basically
although my print out actually said things were being added it says
they are added as tracks and the overall duration remains 0. What am I
doing wrong to cause this?

I'm newish to the QTKit. I'm trying to init a movie object then
place frames in individually. Each frame is an NSImage.
Here is the code I'm using:
qtMovieObject = [QTMovie movie]; //this is defined with the app
starts up
Then for each frame:
NSImage * screenImage = [[NSImage alloc]initWithCGImage:theFrame];
NSDictionary* movieAttributes = [NSDictionary
dictionaryWithObjectsAndKeys: @"tiff", QTAddImageCodecType,
[NSNumber numberWithLong: codecHighQuality],QTAddImageCodecQuality,
nil];
[qtMovieObject addImage:screenImage
forDuration:QTMakeTimeWithTimeInterval(fps)
withAttributes:movieAttributes];
//[[screenImage TIFFRepresentation]writeToFile:[NSString
stringWithFormat:@"%@/%i.tif",tmpPath,frameNum]
// atomically:YES];
[qtMovieObject updateMovieFile];
