when I run video I get molasses

when I try to run quicktime video along with audio in Protools (both le + TDM) everything turns to molasses (bogged down). I know I must be doing something wrong but can't quite find the answer in manuals. I don't believe it's a ram issue as protools is not using all that I have dedicated to it. any enlightening thoughts from any of you nice people in the know?

I wasn't using compression. I saved them as quicktime files in Finalcut pro. When I import them into protools it works with a few tracks but if you get more than a few tracks everything literaly bogs down and it takes forever for anything to work. If you disable the video everything works fine. I have PTle 5.1 on a g4 350 w/ 320 ram as well as a nubus expansion chassis full of cards for 48 track tdm on a 7100 w/ newetech g3 240, 120 mg ram. The same thing is happeninng on both computers so I was thinking I must have something configured wrong, but perhaps these cpu's are just too slow for this?

Mr T you rock! I tried hiding the window and it helped a little, but when I compressed the video it made a big difference. I used a clip about 5 1/2 min long with 23 tracks playing, not too many plugs. It didn't make any noticable difference if the buffer was set to 512 or 128. (native g4 001 of course). I haven't tried it on the tdm sys but it definately improved it big time on the native. Thanks a lot for your tips. Cheers, Tex

hey MR T, I had a similar video problem. I brought some rendered footage form work (DV) home to lay some audio and FX in with PTLE. Everything worked well, I imported the video ( from iMove, which was fine for this project) into PTLE, window shows up , everythings good, i lay my tracks out, get my "mix". The trouble comes when bouncing to disk. The whole thing is slowed down. I thought it might be the 44/48 thing, but I couldnt figure it out. any tips? Would 44 audio play back slower in quicktime than 48? IS 48 the standard for even QT ( I do have the pro version). it was a fun project, I stitting there going "I'm making commercials, sweet"

Kama., I've never experienced that kind of behaviour myself but I'm pretty sure it has nothing to do with movie (session set up?24-25-30 fr/sec.?...). What do you mean by "slowed down"->is it playing slow (like it's been pitched) or does it sound like it's playing OK but slowly desynchronizing (sliding) with picture?

Its pitched down, synched ok. is there a spot to set up framerate? Maybe I missed it. I'll double check T. Thanks
