CS5 After Effects Composition Render Issues
I’m encountering a nasty bug in Premiere CS5 v5.0.4. I’m shooting a lot of greenscreen work and using Ultrakey to do most of the keying, but some shots I need more advanced spill suppression, and for that I’m using Keylight in AE. I’m doing this just by sending the shots to AE with the ‘Replace with AE Composition’ command.
Once I’ve got my shot fixed in AE, I save the project and it updates back in the Premiere timeline. Great! However, once I render, I’m noticing weird duplicate/blended frame issues intermittently throughout my Premiere renders. There doesn’t seem to be a fixed pattern to them, and I’ve double checked my sequence settings and they seem to match. They render without issue if I do a RAM preview in AE.
Has anyone else had this issue? I know the sequence settings are the first thing I would check, and I have, and it should work without issue since I haven’t change anything in Premiere or AE. It almost seems more like a system resources issue, like glitches occur when memory can’t be allocated properly. Anecdotally, I’ve noticed less glitches if I render after a fresh reboot.
Any help would really be appreciated!

I found lots of AE CS5 (haven’t had the same issues with CS5.5) render issues were fixed by disabling the “Render multiple-frames simultaneously” option under multi-processing in AE or the AE render engine.
When I got really stuck and was trying to export my final edit, in one case I simply used AE to render out all the scenes/shots and then just created a copy of the Premiere Sequence and manually replaced each one; it wasn’t fast, and wasn’t pretty – but it worked.
I wish you the best of luck finding a solution that works – it can get very frustrating!

One solution was to make the comp background black in AE, I guess there are working on that bug.

I misread, I thought we were talking about Dynamic linking, Petros is indeed correct.

I thought we were talking about it too…
As far as I know (and I might very well be wrong) dynamically linked compositions will still use AE’s render settings (I’m actually opening up the discussion here.) 😉

That reminds me of a render I did a while back at the last minute (about 16 hours worth with no time to re-render). Had to replace over 50 of those half black frames with stills from the timeline inside Premiere. Fun times…

I just bumped into a wierd-in-a-good-way thing when using dynamic link.
When I render to ram (using Zero) in AE, when I tab back to PrP I can play back that AE comp with no rendering. Apparently PrP and AE share the same ram with DL. But of course eventually I have to render the file in PrP. Just a nice surprise for a change.Tom Daigon

Yep, an extra TB of RAM sure would came in handy for that 🙂

Thanks everyone for all the helpful replies. Unfortunately, I already have multi-frame rendering disabled in AE, so that must not be the issue.
I think in this instance I might just go with rendering each shot out from AE and bringing it back into Premiere. Long-term though I’d really like to get a handle on what’s causing this because as you can imagine it’s a major workflow hangup.

Let me ask this… You say when you render in Pr it is showing this. Is that a Preview Render or render out to another file? Reason I ask is I had something before with using hardware acceleration and wiping between PNG files. It would kind of double up, so a drop shadow would seem twice as strong during the transition when rendering the preview, but rendering out the final product with AME to another file it would be fine. I was able to switch to using software only rendering and the problem would be gone.
I haven’t seen it in the manner you’re describing, but it sounds similar enough.
