In the case of a music video where the audio needs to stream over the whole movie, I do the whole thing in one scene (e.g Yuyu was 6000fr in one scene).
Sorry to sort of jump in on a dead thread, but doesn't that make working on the project very laggy? Maybe my computer just isn't very good, but sometimes when I work on a single scene with a large amount of frames and music the slow down, when drawing, tends to become unbearable... Do you just somehow optimize your work, or something? Or is there just no problem?
Also, I was sort of hoping there was a way to have streaming music span over different scenes, but I guess there isn't, is there?
