render time
hi
i am currently trying to render an animation i created in after effects
i am having some troubles with the render time and am unsure if this is due to my computer being too slow or if the project is too large
does any one have any advice for speeding up render times?
my animation is 1024×576, it will then be made into a dv pal 720×576 project. could i have exported it 720×576 first without rendering the 1024×576 one?
will the 720×576 one look squashed when i render it out?
at the moment it has taken 30 hours to render 18 secs, i am wondering if some of my images are too big in the animation.
thanks for your help -

If you tell us a little about the animation in question – what effects are you using, are you scaling down very large images, etc. – it would help us narrow it down. Certain effects – some blurs, complex particle simulations, etc. – can cause the render time to increase a bunch. Its hard to say whats causing the heavy render times without knowing whats in the comp.

thanks for your reply
yes i am scaling down large images. i made them large so i could zoom into them quite a lot at various points throughout the project. the main effect i have used is box blur to blur some backgrounds. could this slow down the work that much?
thanks for your help -
Could be. I know whenever I use very large images and scale them down, etc., it inflates my render time.
What are your system specs? (processor, ram, etc.)

not so good with this stuff but im using a G5
2 x 2.8 ghz quad core with 2 gb memory is that enough info?
thanks again -
Add memory, and you’ll use all your processors.
Also, output a draft quality version of it FIRST, get the animation APPROVED, then fire out the dog of a render if need be.
Hypothetically, if you feed your machine 24/32 gigs of ram, your render times will probably cut down substantially. I’d imagine you’re using 1 processor right now — either 1 or 2 — but if you dump 24/32 gigs of ram into that box you’ll get 8 processors — so your render times will be either 12.5/25% OF the total net previous render time. But in my eyes that is still unacceptable for a high end slideshow — 30 hours????. (and RAM now-a-days doesn’t cost close to as much as it did when the octo’s first came out)
Also, I prefer Fast Blurs, but if you’re using a box blur, apply it to an adjustment layer above the image. Think about it — box blurring 720*576 vs your native image size is going to save a lot of processor power. If your images are 6k or so, you’re totally hammering your computer applying that effect to it.

also— its probably an Intel — they never made G5’s in 2.8s — they made dual 2.7s.
I’ve also found that AE freezes more with an octo that is lacking memory.

We see inquiries about render time at least twice a week so a search of the forum will yield tons of useful information. (Mostly you’ll see rants form me about working in AE1 and AE2 on glacial Macs. I have no patience with you kids who complain about rendering time.(
Because some of us grew up with AE as the Macintosh evolved, we’ve developed workflows based around making as many decisions about render-intensive effects as late in the process as possible. We use proxies and prerenders whenever possible to avoid committing huge resources to output that doesn’t need to change.bogiesan

thanks nicholas. your information is really helpful. after this project i think i will upgrade my computer.
dave and david thanks for your replies too… some of us are still learning and do not have the depth of knowledge that people like you have, thats why we ask these questions when we are a bit stuck. both of you guys sent back some responses that were a bit unnecessarily abrupt. thanks for replying but its really not necessary if your just going to get annoyed about it!
