I was still tweaking, and the solution to make it playback in realtime was to export the sequence with 200% speed and then reimport it. Pretty tedious, if you ask me. Doesn’t seem like Premiere caches anything, and since I had a lot of timing to do it was impossible without realtime playback.
Also, when rendering the work area (by pressing enter), Premiere stalls completely when trying to play the render. 0% cpu is used, but it’s not possible to do anything in the GUI except to kill the program and restart. Even more tedious.
However, I’ve found another weird thing. I’m done tweaking and exported the whole project to avi to check it. Premiere still skips rendering those video track that hasn’t got the red line over them. When playing the render there are a lot of video skips in the movie, all skips are coherent with the timeline where the red bar is not present.
Why on earth would it do that for the final render?!
