I am attempting to combine prerecorded video with animation in Anime Studio Pro 6.
As my animation gets to frame 9400, I begin to develop problems with the video soundtrack; i.e., pitch changes or speeding up. Often the soundtrack loses synchronization with the video altogether.
How can I maintain synchronization after this point?
(The video is recorded at 30fps and has key frames every 24 frames.)
Even after removing the video layer and then attempting to do the animation synched to the soundtrack, synchronization wasn't possible after frame 9510.
