Q: I'm calling the SetMoviePlayHints function with the hintsHighQuality flag set as described in "Letters from the Ice Floe" Dispatch 11 to tell QuickTime to render my movie at the best possible quality. However, it seems this is a runtime property so the hints are not actually saved with the movie. How can I save these hints with the movie? A: Use the SetTrackLoadSettings function, and specify the track you'd like to have the playback hints applied to (note: if you have more than one video track in your movie and you want the hints applied to each track you will need to loop and call SetTrackLoadSettings for each track).
Here's a short code snippet which locates the first video track in
a movie and applies the high-quality playback hint to this track:
