Hello there

First of all I would like to thanks Brad, your framework is incredible in both ways (Performance and easy to use). I figured out and confirmed throughout Brad's iTunesU videos about the experimentation with Quartz Composer.

My current problem is that I have develop a desk of filters and effects that need apply in 2 ways from the same video input and merge it for render. For example, like in Photoshop, get 2 layers and apply multiply blend mode to the top one. I would like to achieve this with GPUImage, but from what I understand blend modes are for still images or image files right?

Thanks in advance and sorry for my english.

Cheers

Brad Larson

Blend modes work just as well for video as for still images. I've made some improvements recently to fix a few bugs with the blends, so they should now work pretty well with video.
