Trying to get solid green backdrop

[2de_man]

Hi, I am using animations I create in Moho as part of a larger multi-media project that I'm assembling in a video editor. I want the animations on a green backdrop so I can mask the green out later. I make my 'talking head' animation out of several PNG files, put them in a 'switch' layer and sync it to the wavefile, everything's great. THEN I add a vector layer with a green fill and position it so the animation files have a green backdrop but when I render it off as an MP4 the backdrop is pale blue, which is not ideal. What am I doing wrong?

You're using MP4, that's wrong.

Since Moho supports Alpha (transparency), you don't use any backdrop at all. Render with some Codec which supports Alpha channel, like PNG with Millions+ Colours, or Apple ProRes 4444.
