Hi, I'm not a Final Cut guru but I believe the keyboard shortcut you used is CMD 1I found this page very helpful: http://www.nobledesktop.com/shortcuts-finalcutpro5-mac.htmlLet me know if that clears it up or if we need to dig deeper. Thanks.
Hi Steve, That command just seems to turn the viewer on & off
Sorry, I misunderstood the question. I found this discussion. It seems to point to codecs or frame-rates being the culprit: http://forums.creativecow.net/thread/8/1086810If that doesn't help, I'll opt out and hopefully someone more conversant with Final Cut is up early and will weigh in.
I checked that out but I don't think it can be that complicated it was working fine until I typed in some command.
Check that shortcuts list I posted at the top.
Also, save the project, quit the program, and re-open it and check if you haven't done so already.
