I have a film project that was edited on Adobe Premiere Pro CS4 which I tried to edit CS5. When I clicked on the prproj file, I got the following message:
"The scratch disks are write protected or unavailable. To open this project, the scratch disks will be set to your Documents folder. Would you like to continue?"
I clicked "yes", and another message appeared that said "This project contains a sequence that could not be opened. No sequence preview preset file or codec could be associated with this sequence type."
I wonder if it's because I was previously working on PC and now I'm working on a Mac. Or maybe it's because I am using the trial version rather than the real one. Any ideas?
It is most likely that the trial version does NOT support anything MPEG. The full-paid version has no such limitations. If you have anything MPEG in any Sequence, you will NOT be able to edit it.
The full-paid version comes with a 30-day, money-back guarantee, so if it does not work, as you need, just return it within the 30 days, for your money back.
Also, it is possible that that Project contains something that is PC-specific, but that would usually result in a "CODEC missing" error message. Some CODEC's are just Mac-specific, or PC-specific, and will pose limitations. The same can exist if one has Matrox in the original Project, but not on the new machine. BlackMagic CODEC's can pose the same issues.
