Locking existing frames - Slows down RAM preview - After Effects CC

Dec 7, 2013 5:33 PM

How do you fix 'locking existing frames' when RAM previewing? It locks up and is very slow before rendering and I have 32gb of RAM on a 3.4 i7 iMac. I have multi-processor rendering off. It was apparently fixed in an update in CS4, but im still experiencing it. Any suggestions?

    I assume you are referring to Rotobrush. If so, then render your rotobrushed footage to a DI (digital intermediate) using a production codec and replace the usage in your AE comp so you can get rid of the overhead caused by the cached Rotobrush data.

    You might want to give all the info mentioned here. As the original problem was fixed, this may be a new one and we'll need to know more to help troubleshoot.

    Try using .wav or .aiff files for your audio instead of MP3.

     

    What are your memory and MP settings? These can really foul things up if they are wrong.

    Does it do that in any comp with any content as long as there's audio? I mean, if you reboot your computer, launch AE, create a new comp with a solid wiggling around and add some audio, does it still do it?

     

    What about if multiprocessing is turned on?

    Glad I was able to help! Wouldn't hurt to file a bug report.
