Problem with exporting keyed footage through render queue
I am having a very hard time trying to export this footage that I keyed within AE. About half way through the render queue process it freezes and I have to restart AE. Other times, it stops and says “After effects error: adding to movie (-1309)”. I heard that there is a problem with the memory setting so i’ve tried messing with that a little, but still no luck. I’ve always been keying and exporting this way and have never ran into this problem. I am working on a Mac pro 3.2gz dual quad core with 12gb of ram, so the machine can definitely handle this footage. Any help will be greatly appreciated. I am doing this for a living, so I really need to figure out the problem here. Thanks,

first off, i think you have enough ram to have the memory & cache settings at the default settings (max ram usage 120%, max ram cache 60%)… if you get too crazy with those settings it can cause problems and i wouldn’t normally vary those settings more than +/-10% unless you have ae7 on an intel mac…
when the crash occured did you happen to notice what the ram value was at (it’s part of the data at the top of the render queue)?
if that ram value is getting to your maximum ram cache setting (in the memory and cache preference) and then crashing. that usually means that ae is having trouble clearing the ram cache. if that is the case, you can evoke the ‘secret’ preference and set ae to purge the cache at set intervals. this may slow the render some and should only be used if you think that the cache is not clearing properly, then reset after you are finished with that project.
to get the secret pref, hold the shift key while choosing preferences>[anypref], then from the preference window, select the preference pulldown and at the bottom should be one called ‘secret’. select it and set the ‘purge every xx frames’ value to a number of frames that is less than where your crash occurred. so if it crashed at frame 100, try a value around 80.
if it works, then don’t forget to reset the value to 0 when you are finished. if it didn’t work, but made it further in the render before crashing, then you may need to lower the purge setting even more.
if you don’t think it is the ram cache, it could be multiprocessing… you might try disabling ‘render multiple frames simultaneously’ for this project in multiprocessing preference.

Thank you so much. I kept changing the secret purge frame number until i got it to render the entire file. Your help is very much appreciated. Now i wont get fired! 😉
