Corrupted movie ?

Hello

we have a very serious issue here with some qt movies that we create in our application.
we create the movie, we add video tracks, effects, etc..., then we save it using
OpenMovieFile, UpdateMovieResource then CloseMovieFile.

Sometimes, for some unknown reason, the movie file is corrupted when we try to reload it in our editor, or in the Movie Player. Sometimes it crashes the player and sometimes a msg box says 'cannot open file xxxx.mov because invalid media data was found in the movie'.

I have two questions

1) is it acceptable, with QT, to create a _lot_ of video tracks and effects in the same movie ? Maybe there are known issues when there are too many of them...? It's not unusual for our movies to contain >100 tracks. Sometimes when there are a lot of tracks, the playback suddenly crashes deep into some QT code (in 'decompressVideoFrame', but i've seen crashes elsewhere,too...)...

2) Is there an application that would allow us to have a look at our QT movies and maybe check where the problem is ?

We're using QT6 on OSX 10.2

Thanks for some help... Since our qt expert left us, we're kinda worried here ;-( (hence the job offer you've maybe seen a few days ago....)
