I think I ran into a serious bug in Premiere Pro CS5.

I opened an old CS3 project with DVCPRO50 sequences in it, that had denoiser filter on several audio tracks. It converted nicely to CS5, and I was able to work on it with ease, which I promptly did.

Then I had to restart my computer, and I could no longer open my CS5 project. The error was "DeNoiser2. Could not open the bin-file". The situation repeated twice, so I'm sure this is some kind of repeatable bug. The temporary file that was saved for Media Encoder to encode a sequence suffers from the same problem.

I'm trying to tweak the project file via XML editor, but so far no success. If any of you has any idea on how it could be solved, let me know ASAP, I lost quite a lot of work, and I'm very unhappy about it.

Thanks and beware.

Have you submitted a bug report to Adobe? If not, please do:

I did. It was the first thing I did.

I managed to find a temporary workaround. I deleted all binary data for denoiser2 filter in the project file, and then I was able to open the file in "desktop mode". There is some weirdness going on though, I lost my preview files, the prompt for missing files was cutting off the filename after the space (linked correctly though), and after opening the project I could only manipulate menus and timelines - all other panels were oblivious to clicking. Until I switched the workspace to a different one - then the whole thing became responsive again.

Still, the sequences are in "desktop" editing mode, and while they seem to export fine, and it can serve as a temporary workaround, it is hardly a definitive solution.

Ah, I'm on Mac X 10.6.4 BTW.
