After Effects CS4 Render Failed
OK I did the secret prefs and made it purge 30 frames but I still get render railed at the same exact time it failed before I did the secret prefs. I don’t get why it was able to render one of mine fine and this was not. This one was like 10 seconds while the other one was almost a minute.

No one will likely be able to help unless they have some more information…
We see by the title you’re on AE-CS4 – BUT!
what’s in the comp?
What operating system?
How much ram?
How many cpus?
How fast cpus?
Do you have a crappy video card?
Do you have 9 bajillion programs running?
Is your HD full?
Do you have a virus?
Do you have multiprocessing enabled and didn’t leave any ram for the os?I’m sure I missed a bunch, but any one of those, or combination of any of those could attribute to a failed render.
Heck, AE might just be complaining about the type of video you’ve imported.. It hisses at certain codecs:
Dave LaRonde”s Stock Answer #1:
"If the footage you imported into AE is any kind of the following -- footage in an HDV acquisition codec, MPEG1, MPEG2, mp4, m2t, H.261 or H.264 -- you need to convert it to a different codec.These kinds of footage use temporal, or interframe compression. They have keyframes at regular intervals, containing complete frame information. However, the frames in between do NOT have complete information. Interframe codecs toss out duplicated information.
In order to maintain peak rendering efficiency, AE needs complete information for each and every frame. But because these kinds of footage contain only partial information, AE freaks out, resulting in a wide variety of problems."

yep… we’ll need more info.
the purge frames interval will usually only help if ae is having trouble clearing the ram cache during a render. you can usually tell if that is the problem if the render crashes when the ‘ram’ value (seen as the second item from the top of the render queue) hits the maximum ram cache value (usually around 60%).
if that’s not the problem, then the purge frames interval will probably not help much.
aside from what has already been mentioned, you might also look at your comp and see what happens at the frames around that point. it may be that a layer or effect starts or stops right at that point and for some reason that is causing the problem. you’ll also have to check the same point in any nested comps. if that is the case, we can try to troubleshoot it or find a work around.

ACK!
Dave posted while i was typing lol!

it’s around 60% for the RAM thingy…and I’m on Windows 7 RC…my HD has a lot more space so that’s not an issue…for the rest I’m not sure where to find them *sorry I’m not too fond with laptops* lol

Ok so what are you trying to render filetype and codec wise?
-
h264…just going to render it for youtube

H.264 can cause issues..

yeah I do not have the option for OpenGL b/c I’m using Windows 7 32bit

generally, ae does a poor job of rendering to codecs like h.264.
you’d be best off to render lossless, then use a compression utility like mpeg streamclip (free) to output an .mp4 using h.246 compression for youtube.
or, if you have cs4, you should also have adobe media encoder cs4, it actually has a few youtube presets you could use. media encoder can also ‘render’ an ae comp directly, so you may not need to 2-step it (render lossless, then compress that to h.264), although i haven’t compared the quality of one vs the other.
here’s a link to the manual for ame:

And this is why I keep up with threads hehe.. didn’t know about “mpeg streamclip” off to find it now. always awesome when you learn/find something new
