javascript controls of a quicktime movie (update again)

more things learned about the stupid workings of quicktime.
im adding a few more movies into the db for the presentation tomorrow.

what has this taught me?

1. the formular i described yesterday holds up for a movie that is 1:26 long. so youre safe at least for movies of an hour and a half.

2. that compressor is a funky thing. i used to try and squeeze these long qt files (1.78 gig) down to something more usable. it looks like mpg4, 160x120, stereo, 16kHz is passable. it took said movie and shrunk it to 131 meg. add in that it made it progressive and suddenly the wait isnt too bad for an hour and a half of video - esp since you arent reloading it all the time now.

3. but the funkiness of compressor? oh yes.
thats when you encode these files (or save them from mp4 to mov inside of qt) that this magical 'rate' changes. normally, the movie has this magical rate of 600. (see yesterdays post for info on that.)
but then, during some of this conversion, it seems the rate jumps up to 1500. i cant find any setting for this, i cant change it or access it at all. but yet, my movies were back to misbehaving until i changed the rate from 600 to 1500. thanks again qt - this is a really great feature.
