Are qt-tracks switchable per Applescript/Automator?

Question

my idea is the following scenario:
I do have a Quicktime.mov containing TWO video tracks.
What I'm looking for is a 'single button'-solution, which allows to switch between both tracks.
possible? how?
any ready-made scripts/actions avail?
to give additional info about my project:
I'm recording soccer games with two (... four) cameras simultanously.
the team's coach needs a 'dumb' solution (no word about soccer-coaches! ) , to see the action from one or the other perspective.
it's simple to stitch the two videos into a single mov, and I do know how to 'select tracks on display' in QT7pro.
but he doesn't.
my idea is, to create a (local, on usb-stick) website, offering that video. (and additional info)
or, even better, a Pages/iBooks document .......
plus a 'switch'-button, which is a kind-of applescript/automator action/whatever, which changes 'priority'. that way both videos are always in synch.-
anybody any idea?
thanks in advance
k.

Hi Karsten, it's been while since I last saw a posting by you here.
Simplest approach would be to create a file containing side-by-side or over-and-under display of two angle cameras or a combination of the two to display four simultaneous camera angles. If you combine, align, and offset the video tracks in QT 7 Pro and then compress to your target diplay file, then the sync alignment of the source tracks will be locked in the combined frames of your final output file unlike individual source tracks each of which might drop frames independently during playback in a multiple video track standalone file. This, of course, means that all viwing angles are displayed simultaneously and the viewer must switch his or her attention to the specific angle of interest but does allow you to play the file in any compatible media player, on a web site or on any compatible mobile device without having to program track switching which may or may not be compatible will all of the viewing options previously mentioned.
A second approach would be to key your video tracks to alternative language options and have the viewing angle (track) change when the associated language is selected. Unfortunately, this only works in apps/on devices which support built-in alternate languages and/or multiple video track control. For instance, it QT X and QT 7 will switch the video track when the appropriate language is selected but VLC has separate built-n video track switching controls and iTunes doesn't recognize alternative video tracks. Unfortunately, there is a secondary problem with this approach. Playback can sometimes become jittery after switching tacks. This problem can be correctly by momentarily stopping playback and then restarting it but this can be a pain.
A third option might be the use of sprite buttons to script switching between tracks. Unfortunately, I can't say how difficult or successful this approach may be based on any personal experience.
