Blending Modes

Posted by Daniel J murphy on May 12, 2005 at 3:58 am

Well, I finally got after effects today. But I’m having problems, and I’m sure they’re my fault. I’ve searched the forums and help files to no avail.

The blending mode doesn’t do anything. I have a video track, and on top of that I put a solid gray box with the opacity at about 80%. When I adjust the blending mode of the box, nothing happens. This is how I would be doing it in Photoshop or (maybe I shouldn’t even admit to using it in this forum..) Motion. What am I doing wrong? Thanks alot.

BTW, AE 6.5.1, Dual G5 2 Ghz

Sometimes modes don’t respond to 128/128/128 gray. Try red as a test.

Are you sure you’re changing the mode of the top layer? Is there a layer that it can affect beneath it? Are you changing Mask modes instead?

With a layer selected and the modes panel visible in the timeline, you can cycle through its modes by hitting the + or – keys above the main keyboard. Don’t forget to hold down shift. 🙂

Well maybe my computer just needed to take a nap. I woke up this morning, opened the project and everything was blending the way it should. Go figure. Thanks for your help.

Hi,

I’m having this exact same problem! The blending modes in AE don’t do anything. Does anyone have a fix?!?

Thanks,
Jack

So… I’ve found the problem on my system…

My blending modes don’t work when Edit > Preferences > Previews > OpenGL Info > Quality is set to “faster” but the blending modes do work when Quality is set to “More Accurate”. I can effectively enable and disable my blending modes by changing this quality setting!

My OpenGL renderer is an NVIDIA GeForce PCX 5300/PCI-E/SSE2/3DNOW!.
My OS is WinXP SP2
After Effects 6.5.1 (re-installed several times)
Athlon64 2.4GHz

Please do let me know if anyone else has this problem.

Thanks,
Jack.
