terrrrrrible rendering
on Mar 17, 2011 at 9:33:10 pm

I am just trying to render out 3 seconds of 1920x1080 footage with keylight applied and the render fails within the first frame.

I have never had this much difficulty rendering out something like this.

I gave after effects set to purge every 15 frames, Open GL is NOT activated, I gave most of my 4GB of RAM allocated to the app.

Anyone have a clue what could be going on? This is giving me real hell.

[malcolm DeSoto] "Anyone have a clue what could be going on?"

Based on the information available, it could be:
You're running AE 8, 9 or 10 with multiprocessing turned on, and you have insufficient RAM to use it
You're running AE 8 or 9 and you're using footage from a DSLR, XDCam, Flip Cam, Smart Phone or HDV camera, and you you're running into them ol' long-gop problems
You turned off Open GL for previewing, but not for rendering
That's everything I can think of.

Multiprocessing is not turned on
Open GL is not turned on for previews or rendering.

The footage did originate from a DSLR. I'm re-exporting it from Avid using an animation codec to see if that makes a difference...

Although, I've done projects in the past using footage derived from the same camera with no problems. Odd that it should just act up now.

Well, no idea what the deal is. Changing the encoding doesn't help.

Malcolm...sorry to hear of your troubles. I have had plenty with AECS5 as Adobe's new memory architecture is (I believe) a work in progress.

I don't know if this will help, but I had tons of problems *until* I did all of the following:
-Only used animation codec
-Added RAM
-Purged Preferences
-Rebooted when I saw problems
-Used Multi-processing but with generous RAM allocation and limited CPUs

I would also check your Activity Monitor and make sure that all instances of the Adobe AE renderer are properly quitting. Sometimes they will hang without you noticing.

Life is full of funny particles.

I ended up setting it to purge after every frame and was able to render out 10 or so frames at a time :/

This is unrelated to your question, but it isn't a good idea to shoot green screen with DSLR cameras--you're going to have artifacting around your key. DSLRs shoots highly compressed footage with not enough data collected in the color channels to make a clean key.

I don't think that's true at all, Kevin. While it is certainly compressed, you can definitely get a clean key if you use proper lighting and know how to use keylight. I've been using a DSLR for about a year now and have had great keying results.

As for the rendering issue, I'm not sure what happened. I was able to render out the project (painstakingly slow) but it finally all rendered out. When I have more time, I'll scrutinize the project more closely.

Based on that slow render, it sounds to me you'll find that:
1) you're not running AE 10 yet or haven't updated AE 10 and
2) you're not converting DSLR footage to a lossless codec before you use it in AE.

You can do it, but you're not going to get as clean of a key due to the chroma subsampling compression. Professional video cameras have three CCDs, one for each color, or a camera like the RED has no chroma subsampling. I personally love HDSLR, but would never shoot green screen with one.

Dave, I've tried a number of different codecs. I am running AE 9 though.

Kevin, You are correct, if I were shooting with a Red, keying would be easier.
