  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

I don't remember if it was an option in CS3, but I had never used open GL rendering for final output until now. And up until about an hour ago I was really happy. Render times were faster and everything looked good using the open GL renderer, that was until I took a look at the final output. Much to my dismay it looked as if it were rendered using a draft setting. Things were sharp and colors were good, but edges had an aliased look. I started re-rendering without using open GL and not only have the aliased edges gone away but the overall picture quality is sharper and just better.
My footage is 4K and 3K being output at 1080P, Highest quality RED settings in after effects and OLPF compensation off.
Just thought I would put out a warning to everyone out there that might try to use this setting to speed things up.
In the attatched jpg this is a 100% crop from the 1080P DPX file. Notice the edges of the photos. This may not seem like alot, but it gets really pronounced as the aliasing is in motion.
 
Might be a specific setting that needs changing? It would seem a bit counterproductive if it could only do it in draft mode or the like....
 
same happen to me.... did you find a solution? I got a lot of clips waiting for VFX in AE, then i need to send them back to Final Cut Pro for Editing and grading in Color...

Open GL has been available in AE for some time, however... it's got it's issues. Your GPU has to be robust enough to be effective, and using certain effects and working in 32 bit mode make Open GL a non option. In essence I ignore it, let the CPU do the heavy lifting, and for long or complex renders, I turn on multiprocessing and adjust the RAM cache size down to leave enough memory for each processor to crunch on.
 
It's my understanding that Open GL should be used for previewing purposes, especially when using 3D capabilities of After Effects, because you need more speed than quality.
For final renders you need quality, so what Brandon said is the way to go..
