Cant render
on Mar 24, 2010 at 2:33:21 pm

Hi everybody.
I have an annoying problem with rendering from AE to my pc.
I choose render setting, render module, press on the "render" button - and everything goes smoothly. I can see the render bar moving forward.. UNTIL the effects part, then the render bar stops moving.
AE is not crashing, and I can still press on the "stop" button, its just that the render bar WONT MOVE.
I tried to give it a full night, 12 hours, and nothing. always stops at the same point.

and... if I'm trying to ram preview the movie...its ok.

so any ideas guys? I cant finish the movie like this!

I'm updating the AE right now, thank you dave.
about the openGL, right now its "openGL - interactive", to what should I change it?

Off
Wireframe
Adaptive Resolution - OpenGL Off

im not using multiprocessing, I dont know what it is.
the two links you wrote in your post are dead by the way.

[efraim or] "...to what should I change it? "

You don't change it for previewing, you change it for rendering. The instructions for enabling and disabling it are near the bottom of this page:
http://help.adobe.com/en_US/AfterEffects/9.0/WS3878526689cb91655866c1103a4f...

[efraim or] "im not using multiprocessing, I dont know what it is"

Do you have "render multiple frames simultaneously" enabled in Preferences? That's multiprocessing. Until you know if your system can handle it, you should disable it. Those links were down only for a short time. Try them again. They explain if you can use multiprocessing, and how to do it.

"To get the most from After Effects CS4 out of your computer with eight processor cores and a 64-bit operating system, you would have 32GB of RAM..."

eight cores? how is it possible? I thought that the max cores right now is 4. even the newest i7 got "only" 4 cores. and 32gb ram? I have never seen more than 8gb to sell. I dont get it.

anyway I got win7 64bit, 8gb ram and intel Quad Q9450.
I think ill try the multiprocessing, maybe it will help.

the opengl by the way is OFF, and I updated to the newest ver of AE.

thanks a lot Dave, Ill keep you update.

There are a LOT of people who have dual quad core Mac Pros, myself included. 2x4 = 8. I'm sure there are dual quad core Windows boxes, too.

Just remember -- if you have more rendering problems, that's the first place to look.

Apple has already said the next Mac Pros will have 12 cores.


[efraim or] "the "Prevent DLL address space fragmetation" is ON. no idea what it is, to keep it on?"

Ask a Windows AE guy about that for sure... but I would, if that's the default.

ok Dave I CAN render now with no problems but one.
after 30 seconds of the movie the render will stop.
there is nothing to do to effects...even if Ill render simple footage.

seems like after 30 seconds (of the movie, not real time) there is not enough ram or something else.

I tried to disable multiprocessing and it wont work.

any ideas Dave?

You can open the Secret preferences by click on Preferences while holding down the shift key. Find the setting for a purging -- you can set it to purge after a certain number of frames. It slows down the render but helps you get done.

If that doesn't work, I'm out of ideas.

...unless, of course, you still trying to use the wrong kind of footage.

hi !!! if you are using CS4 try this :

1 - Enable caching frames to disk by selecting the Enable Disk Cache preference

2 - Purge RAM and disk caches (choose Edit > Purge > Image Caches)
For the best performance, select a folder that’s on a different physical hard disk than your source footage. If possible, the folder should be on a hard disk that uses a different drive controller than the disk that contains your source footage. The disk cache folder can’t be the root folder of the hard disk.

if thing changed Inform me Thanks

no Ahmed, unfortunately it didnt.

I stopped trying though. it aint that bad.
I CAN render 30 secs each time, so Ill render my movie 2-3 times, thats it. then Ill join all the part with Premiere.

thanks for trying, especially you Dave.
