HI, I have a serious problem. I have to do a music score for a short film (in a very short period of time), and the synchronization of musical elements & video material in this project is VERY critical, but my problem is that, when playing the the score (using gigastudio instruments) & audio & video material from Sonar, the video is totally out of Sync (not playing in realtime, freezing, slowing down... like the machine can't handle it !). But the computer is pretty OK(Athlon XP2000+, 512MB DDR, 2xMaxtor Diamondmax9 7200rpm, M-audio DELTA 1010 for giga) and I have seperate HDD's for Gigastudio & Video, as I know both Giga & Video are very HDD hungry. But when I, for example, start the music from Sonar (also with gigastudio instruments), and play the video from Mediaplayer... the video plays in realtime, only not integrated in sonar. When I turn gigastudio ports off, Sonar plays the video well... I have to mention that the problem is present regardless of what codec/number of keyframes, I use for VIDEO. Is there any possible solution to this problem, or do I have to switch to some other MIDI/AUDIO/VIDEO software ? (Nuendo, Cubase SX ?) Please help !
