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.
Hi Gerard, I'm not referring to Rotobrush. It happens whenever I want RAM preview anything. It seems to be an issue with the audio. When the audio is muted in RAM preview it works quickly and normally. When you want to have audio playback, it locks up for 20 sec saying "Locking existing frames" before it renders and playbacks. It does this every single time, even if everything is rendered. The audio is a .wav file. Looks like people have had this issue in multiples verisons of AE - even though there was a 'fix' in CS4.
Any suggestions? It's beginning to drive me a little insane...
I'm using a .wav- NOT an MP3- tried using AIFF - same issue. Anytime there is any audio (triedn just a movei exports audio as well)- AE locks up.
I have 32gigs of RAM with the maxium set to use with AE. I have multiprocessing turned off.
Its Adobe AE CC (updated) on MacOSX running Lion. No 3rd party plugins. 32gigs of RAM, 3.4 iMac. It's a RED sequence 2k (5k footage). Audio file is .WAV - but the same issue happens with any audio in the sequence. Need anymore info Szalam?
"Locking existing frames" locks up the machine for 20seconds eachtime.
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?
Wow! Found the solution, and nice little bug in AE. Thanks for the suggestion of testing out audio in other timelines - the audio worked - so it had to be the sequence. I went through all 456 shots and turned off the source audio, and now it doesn't lock frames - or only does for a fraction of a second. Looks like everytime you want to preview RAM AE wants to check EVERY audio clip in your sequence (even if you're not previewing it!)
Now back to work...
