What’s the goal of OpenGL in render settings?

[Barend Onneweer]

Well, like you said, it’s faster, but depending on the project you lose quality.

For some projects OpenGL render is good enough, but in some cases it just doesn’t cut it.

Nevertheless it’s nice to have the option to render in OpenGL, if you need to turn out a fast preview.

Ok, now this make a sense to me: getting a faster render and using it as a quick preview.
Yes, good option to have 🙂

And also, it’s an option for getting the exact same render conditions of your previews. Some people like that, just like the box blur plugin.

Apparently AE 7.0 can take advantage of some graphics cards’ abilities to render out new high fidelity openGL, but I haven’t seen those results yet.

I’ve been trying AE 7 with opengl and the results are MUCH worse than in AE 6. The whole 3D space completely shifts to something unrecognizeable from the original project (and from previews in AE 6). I had high hopes but am actually feeling like this is a step back. Am I missing something?

[Barend Onneweer]

Huh?

What card and drivers are you using?

I tested it on a Powermac 2ghz dual processor – the video card is an ATI Radeon 9600. In that test the OpenGl preview looks nothing like the actual render. I’m thinking of buying a Quad and wondering if it is necessary to upgrade to the Geforce 7800, or whether the 6600 is ok for AE.

It says that the ATI Radeon 9600 doesn’t support high-fidelity previews in AE 7.0: “Does not provide OpenGL previews for anti-aliasing or 2D motion blur.”

The nVidia board should definitely produce better results.

Thanks, didn’t notice the *. Is it true that motion blur and anti-aliasing is not supported in OS X at all?

No, not true. There’s just a limited choice in graphics boards that support it. But the nVidia 6600 – 6800 and 7800 should do fine, just as the Quadro FX 4500.
