Can I alter this code so that it only reads and displays the Video and Sound track? In fact this is how the QT Inspector handles multi track clips. It omits everything except the Video and Sound data. 

Hello Paul,

What you could do is create an array of audio and video tracks only. Try the following. HTH.

Jaime


if (movie)
{
[mFormat setStringValue:@""];
NSMutableString *trackFormatStr = [NSMutableString string];

NSMutableArray *tracksArray = [NSMutableArray array];
[tracksArray addObjectsFromArray: [movie tracksOfMediaType:QTMediaTypeVideo]];
[tracksArray addObjectsFromArray: [movie tracksOfMediaType:QTMediaTypeSound]];

int i, tracks = [tracksArray count];
for (i=0; i<tracks; ++i)
{
QTTrack *track = [tracksArray objectAtIndex:i];
if ([track attributeForKey:QTTrackFormatSummaryAttribute] && ([track isEnabled] == YES))
{
NSString *formatStr = [track attributeForKey:QTTrackFormatSummaryAttribute];
if (formatStr)
{
[trackFormatStr appendString:formatStr];
[trackFormatStr appendString:@" "];
}
}
}
[mFormat setStringValue:trackFormatStr];
