Hi, Rich. NSValue has no direct conversion method (well, not at a high level), but NSNumber inherits directly from NSValue. Thus if you replace NSValue with NSNumber in your second and third lines of code, you will be then able to say [durationValue floatValue] or [currentValue floatValue].

I don't know much about QuickTime controls, so if something else is wrong with this method I might not have caught it.

Cheers,

I am trying to use the ProgressView / Cell class from the developer sample code to create a progress bar for a QTMovie.
I want to get the status of the movie as a percent from currentTime / Duration but do not understand QTTime. Code:
NSDictionary *myAtts = [theMovie movieAttributes];
NSValue *durationValue = [myAtts objectForKey: QTMovieDurationAttribute];
NSValue *currentValue = [myAtts objectForKey: QTMovieCurrentTimeAttribute];
How do I get a float value from an NSValue?
Thanks, Rich
