Hi Trevor,
Many thanks for the guidance.
I am working on it but noticed something odd happens as soon as a movie is loaded (also happens with the example Movie Editor). The Movie controller flickers continuously (though not playing) and processor usage rises to 100%. Sometimes it recovers when focus moves to another window outside Rev, but it also seem to happen if I just add another control.
On saving, it seems to often (but not always!) run at 100% indefinitely.
I suspected this was a rev problem but I went back as far as Rev 2.2 with the same problem, so I'm now thinking its an 'XP' problem.
I have XP SP2. I have tried on two different PCs (different motherboards, different firewalls and even different versions of AntiVirus software) but they give the same effect.
Have you seen this before?
Cheers Steve

Hi,
Is it possible to extract an audio track from a QT movie, edit this in an editor then paste back into the movie?
Hi Stephen,
What you want to do is possible. A couple of things:
1) qtCopyTrackToScrap puts the track you specify on the clipboard and you can then paste it another movie from within Revolution or using a program like QuickTime Player. I haven't tested this with other apps however.
2) To insert the current movie/track on the clipboard into a player object in Revolution you can use qtAddMovieSegment which will insert the clipboard at the currentTime of the player object in Revolution.
3) There is no call to delete a track (I will add one though, didn't realize that was missing). This means you will have to do a workaround to accomplish what you want using the external.
If you just want to move a track forward 200ms then you could do the following:
1) Create two player objects.
2) Load your original movie into player object 1. Call qtInitializeEditing.
3) Call qtNewMovie with the path where you could like to create your new movie. Load this into player 2. The currentTime should be 0.
4) For all tracks except the audio track in player object 1 you would call qtCopyTrackToScrap then add the track to player object 2 using qtAddMovieSegment (do not add scaled).
5) For the audio track use qtCopyTrackToScrap as well. Then set the currentTime of player 2 to the time where you want the audio to begin. Now call qtAddMovieSegment and the audio will be placed at the new time.
6) Use qtSaveAs to save the file.
7) Go vote for bug 2254 <http://support.runrev.com/bugdatabase/show_bug.cgi?id=2254> because you really don't want to have to call qtSaveAs after editing. You want to be able to call qtSave :)
Accomplishing this same thing will be much easier once I add a qtCutTrack/qtDeleteTrack call. I will try to get this in before I (one day) release version 1.
