  • Premiere Pro CS6 is not playing back

    Posted by Jack Slattery on October 9, 2012 at 7:15 am

    I recently came back to a project i was editing on Premiere Pro CS6 on my Mac OS X.

    However when i press spacebar or click the play button, it doesn’t move. Not even a frame.

    I did adjust a couple of settings in After Effects CS6 recently to create faster rendering, but i’m not sure if that would create any problems.

    Is this just a bug or what? and how do i fix it?

    (Note: If you can answer as basically as you can that would be a great help because i am still learning all the computer details and i’m a film student.)

    I was just about to post about what could potentially be the same issue.

    Try removing sound from the timeline. For some reason, our copy of CS4 developed a bug after we upgraded our network. If you import footage with a soundtrack captured at 44.1k, the video refuses to play. Hitting play or space only results in the program monitor flickering between play and stop.

    I’ve tried converting some audio to 48k and that got round the issue. Not ideal in the slightest though. Is this any help to your situation?

    I’m not sure it is the same issue but it does sound very similar.

    The difference is though, that when i click play or press spacebar, the button does change, but it doesn’t change back. However, when i click on stop or press spacebar again, it either doesn’t change back for a few seconds, or doesn’t change back at all.

    I did have a go at converting the audio, but that didn’t seem to change anything, i figured it could be a footage issue as well but that doesn’t seem to be it either.

    If i try and create a new project of any type it refuses to play any footage or audio i put into it.

    Thanks anyway.

    Sorry mate, bit stuck on that one then. Is the computer you’re running it on up to scratch? Enough memory? Checked the cache isn’t writing somewhere unreadable?

    I actually just had this exact same problem. Was working fine on Friday, I come in today and this is now happening to me.

    The only thing I can think of is that I just updated Premiere.. a bug in the update perhaps?

    Figured out a solution. Under Project > Project Settings > General, I changed my playback from Mercury Playback GPU Acceleration to Mercury Playback software only. A dialog box popped up, and I deleted my previews. Premiere worked fine. I then switched BACK to GPU Acceleration, deleted my previews again, and it was good as new. So it fixed it, but not sure what the problem was. Maybe my previews just needed to be deleted? Either way, hope that helps.

    I’ve just tried doing what you suggested, but when i go into the project settings, the “Mercury Playback Engine Software Only” is the option selected and it is greyed out and can’t be changed. All other drop boxes are able to change.

    Did you get some sort of extension to change that?

    Sorry if this is a stupid question.

    Not a stupid question. My machine uses its graphics card to accelerate rendering, which allows me another option in that menu. I’m a little fuzzy on the details, but it’s basically a hardware thing I’m pretty sure. Not sure what to do in your case.

    I’m running OS X 10.6.8 and I just updated my PP CS6 to 6.0.2. Once I started PP I can’t play my sequence at all. HELP! Is it bc I don’t have Mtn. Lion 10.8. I know the update says it recommends that you have OS X 10.8 but why should that cause no playback.

    Any help would be great. Thank you!

    Have you tried creating a new empty sequence like your old one, then copy and pasting the old timeline into the new one?
