As a test not long ago, I took a project set up on a PC CS6.0.3 on a USB drive (every file was in a single folder including the conformed audio) and used it on a Mac running CS6.0.2 The first thing I did on the Mac, was to set up a new project on the Mac (on the USB drive) and go through all the preferences etc to make sure that they were the same as they were on the PC. Then I opened the PC project. I had to re-link the media and the Mac then proceeded to conform the audio (so I ended up with two sets of conformed audio) but it did then work.
I'd suggest looking carefully at what the sequence settings were on the Mac and then compare them to what's available on the PC.
Thanks for the reply Andrew but the sequence settings haven't been changed. I'm trying to open the project file not import it. Also I've noticed that Macs are A LOT better at opening PC files in general (which might be why you had more success), but if you try to do it the other way around (mac to PC) which is my case, that's when problems tend to occur.
So unless I'm supposed to be importing the sequence not simply opening it, then I don't think this is the answer to my problem. Anyone else have any ideas?
Just to be thorough I figured I'd take a screenshot of the exact error:
One possibility is if the editor on the Mac has set his preview files to be QuickTime using the ProRes codec, you will get this error. The editor on the Mac will have to change the preview format for each sequence to something you have on the PC.
Already saw a similar thread Kevin, didn't solve anything.
I actually figured out the issue. We were using a custom preset for the sequence that didn't exist exactly the same on both systems. When I instead used one of the default options it fixed the problem with incompatibility. So the solution is to either use a standard preset or to make sure you copy over the preset file as well or if that's not possible, re-creating the custom preset with the exact same settings and file name SHOULD theoretically work (haven't tested it yet).
Thanks for all the suggestions though guys!
