Why does after effects take so long to render??
I’m rendering a video in AE as uncompressed AVI; the video has NO effects and there are two layers. It is 13,000 frames. Why is
it rendering at 1 FPS?? It’s really frustratingSpecs are:
Pentium 4 2.8 ghz processor
512 MB RAM. -

Other potential problems could be the size of the footage. Blending modes will increase render time slightly. Using color management will increase render time slightly again. Separating fields will increase render time slightly… etc. However, I think the most likely culprit is an interframe compressed codec (like those that Dave mentioned).

yeah, it is natively an mpeg-2 file.. 🙁 guess I just have to deal with it, right?

You can transcode it into another codec that doesn’t use interframe compression, unfortunately most of these result in much larger files. Photo JPEG provides a good balance of size and quality.
You’ll need an application other than AE to do this. QuickTime Pro will work, but there may be other better options available to you depending on your platform.

You probably need more RAM, your sig says you only have 512 MB.

I share in your frustration with this issue. I have a powerful enough computer that I would really hope it could chew right through these rendering jobs… that being said.. the average render time for me is 4 hours, the average length of my composition being 3-4 minutes… This includes an audio mp3 along with whatever footage or video etc… however on my last job I animated a 2d photo by chopping it up in photoshop by foreground, mideground, and farground etc.. so basically I’m importing 4 or 5 images into AE.. I drop in the audio track… with no real effects aside from manipulating the images with keyframes.. it took 4 hours… I’m on my second render right now as I forgot to include the audio in the first go round…. which means.. just to manipulate the images alone took 4hrs and 57 min!
Thank god for my mac and apple motion!!!

Have you enabled multiple processors in your preferences?

Hmmm.. I’m not sure that I have done this.. is it possible and or safe to change this setting during rendering? I have 2 1/2 hours left! I haven’t even checked the core setting.. do you know what it is set at by default?
Another question… does it effect your rendering job if you open the partially rendered file and watch it up to the point where rendering is ongoing?

Can’t change preferences in middle of a job
And no, bad idea to open a move while rendering.
That’s why many write image sequences
