Hello,

I am looking at the Scrolling Text FxPlug Sample code, and when used in a FCP sequence it renders a solid green image in a sequence with these parameters: 960x720 HD 16:9, HD Pixels, No filed dominance, 29.97 fps, ProRes 422. This happens when the effect is rendered to disk, not for regular display.

In a Standard Def PAL-DV sequence everything is fine.

What might cause this?

I don't know specifically, but usually when you get an all green frame, it's an indication that a Y'Cb'Cr' buffer was filled with 0s. In Y'Cb'Cr' space, (0, 0, 0) maps to green. (I think this is because the luminance channel is -128 to 127, so it's really mid-green, no red, no blue, or something like that.) So it may just be an indication that nothing is rendering for some reason.
