Hi Harmy, the error you're describing is very weird.
I work a lot with premiere CS4, but didn't entcounter anything like that.
But, it is to be said, that H264 is generally not a editingfriendly format and one would be better off with antything else.
But converting the whole movie into losless is a monster, that's for sure. I'm also not a fan of converting into another lossy format, since you're always reencoding and something can be lost in the process...
I'm not sure what's the way to go. How did you manage with your other versions? Were they also H264? I assume... so what changed from then, when everything worked fine?
Is it something from your setup? Or is it just a different file? How is it different from version 1.0?
If you got enough horespower and space, you could reencode the wohle movie into losless.. ore make an imagesequenz out of it... Tifs, LZW compressed.. or even JPGS with best settings (I know premiere reads tif sequenzes, but Im not sure about jpgs.) You could split the movie into a certain number of chunks, so it's not one big thing.
I would be glad to offer a little donation for a new harddrive, etc.. and maybe others too.
