Hi Michael,
Wow thank you SO MUCH that works!!! 🙂 Why didn’t I ever think of that, hehe. What a relief!!!
Also, while I’m at it, do you know why one of the layers with the noise effect (they’re all copies!) shows a strange behavior? That happened before the precomposing and I can’t figure out why! When I preview it in AE, the light flash looks different than in a rendered version in Premiere! For example, in AE the flash moves from right to left, and in Premiere from left to right and it looks differently, too, making that the second photo actually shows at the wrong time (while in AE it’s revealed exactly at the right time because the flash is different!) Because the AE version differs from Premiere it’s also kinda tricky to tune it perfectly. And this is the only layer that does it, the other ones seem to be identical… How is that possible?
I was able to solve this problem by making a different copy of the layer with the noise effect, but it’s just wondering how it can be that AE and Premiere previews aren’t identical, that seems so very strange! Thanks again. 🙂
