Render time is extremely excessive

Help me out when you say memory allocation…what exactly would you set the above settings to, in your experience? Thanks.

This depends on the comp. I’d try 2 GB and see if it works. If the RAM requirements of the comp are too high for your settings and available resources, multiprocessing will fail and the system will revert to foreground rendering.
Check Activity Monitor. What does CPU and memory usage look like during render now?

Ugh. So I tried rendering to a PNG Sequence, and look what happens:
Here is my CPU usage:
And here is the render queue:
That’s ridiculous! I’m trying to follow everyone’s advice, render as an image sequence in AE and import to Premiere for better rendering, but something MUST be amiss with my AE configuration or project workflow. But I don’t even know where to begin on troubleshooting.

If you set the viewer to full quality, how long does it take Ae to render a frame when you advance the CTI in your main comp?

7 minutes and counting (still not done, still have the yellow barber pole progress bar).

[Ryan Hannebaum] “7 minutes and counting (still not done, still have the yellow barber pole progress bar).”
How did you get anything done while you were working?
A few possible render hogs:
- Ray-tracing
- 3D
- Depth of field
- Motion blur
- Time-based effects
- Expressions
- CPU-intensive effects
- Disk-bound footage
If you can share a piece of the project, maybe one of us could take a look and offer an opinion.

Now you see my problem. 🙂 What would be beneficial, a screenshot of the layer stack, or the actual preview pane?
I do have quite a few wiggle() expressions and some motion blur. No Ray-traced though.

May I suggest you turn off a whole bunch of layers so that the comp viewer renders are fast, then add them back in one at a time, trying to find the ones that are slowing you down the most? Then we can take a look at what’s unique about those slow-to-render layers.
Of course, if you just have a zillion layers, it could just simply be that that’s how long it takes to render.

Time sensitive AE comps should not be rendered on a MBP or any laptop. They don’t have near the processing power of a workstation. Does your company not have a dedicated render station for these? If not they need a serious review of their tech investment.

OK, I think the long pole in the tent is a collection of 9 point lights that were along a railing on the back wall of my 3D space. When I turned them off, the preview pane rendered a full-quality frame in 28 seconds.
Obviously a huge improvement over 10+ minutes, but 28 seconds per frame with 10,405 frames is still ~81 hours, which is still too long a render time for me to live with, for a 7-minute-long video.
Thoughts?
