Here’s an interesting experiment… trying to find the source of the “Locking Existing Frames” ram preview problem without effects or expressions. I just made a solid in a blank project, then keyframed rotation and position values, duplicated the layer 20 times and then pre-comped it. Then I duplicated that pre-comp 20 times and them pre-comped it again. Then I duplicated that pre-comp 430 times then made a new composition out of all those pre-comps. Added an audio file, ram preview and… spinning wheel at the locking frames stage re-created! When I remove the audio, the problem disappears and it renders instantly. With the audio in, I started removing comps until the spinning wheel lasted a reasonable amount of time, about 10 second wait at 150 comps, then 3-5 seconds at 120 comps. It just seems like AE can’t handle both audio and a high volume of comps. It definately matters what you put in the comps, but this was done with just a few solids. Now, with this in mind, and if we take audio out of the picture, AE is doing a pretty damn good job running my project with so many expressions :P

Ok after spending 2 full days relinking all expressions (thanks to Paul Tuersley’s pt_expressedit), it appears that I have excessively over 15 000 expressions …. :bashfulcute: As you guys suggested, I’m ready to bake some of them. A big majority of them are linking the Stroke effect properties to a central controller. Any idea how to bake expressions or effects en masse?

Love it. Kind of makes me want to dunk my head in purple. How long did it take you to make?

What beautiful timing. Adobe just sent an email to reset passwords.

I’ve got 16gb at the moment… unfortunately the iMac I’m working on maxes out at 16. Multiprocessing is turned off. I’ve tried with it and there doesn’t seem to be a difference in this case. Right now I’m trying to work out different ways to link my expressions, trying to centralize them more. Looks like I’ll need to compromise somewhere and maybe drop some automated functionality.

Thanks for the feedback. Indeed @Massfocus this is yet again one of the many hard lessons I’ve learned this year… I was definitely overzealous in my approach. @felt_tips Next time around, I’ll be breaking the project up into smaller ones like you suggested. Unfortunately that would be next to impossible in this case, and baking them or using proxies would break the functionality of the project. The project is a pretty heavy character rig so it makes it really difficult for me to take off features once I’ve implemented them. I’m sitting with my stopwatch troubleshooting the Locking Existing Frames ram preview lag that’s stuck at 1m18s before rendering.

Some funny discoveries I’ve made so far:
  • The lag disappears entirely when there is no audio in the project (or muted ram previews)
  • The lag remains with audio when I delete all effects and expressions
  • The lag disappears with audio (mostly, to 0m15s) when there are less than 400 comps
Kind of a terrifying situation for me as I’ve been working on this project since June… would be a lot of work to throw away :S I’ve managed to reduce from 482 comps to 442 in a day, so hopefully with another day’s work I can get it back down to 400 comps. Fingers crossed that this will actually make the difference.

Well thanks for the suggestions guys. After a bit of tinkering, it looks like both issues 1 and 2 are coming from simply having too many compositions in the project panel… I guess it’s just too much for the software to handle. 482 comps total with 5000+ expressions… I went back on previous iterations and found that major slow-downs started happening at around 400 comps. hmmm now to reduce this project somehow :S I wonder if there’s a cutoff point or a safe zone, any ideas?

Interesting idea @EFEKT , I wish I could divide it up but all the compositions are interlinked in with expressions… Maybe I can look further into that though.
As for the ram idea, I wish it made a difference. I have 16gb of ram and I get the same results when opening the project in CS4, CS5 and CS6 with or without multiprocessing (but in CS6 the AE user interface buttons and navigation becomes slow, oddly).
There aren’t any 3D layers in this project btw. I wonder if it has to do with the amount of layers with expressions applied you can have in a single composition. Maybe it makes a difference if I pre-comp batches of layers… uuuughhh looks like this will take a while to solve.
