Rendering out PNG Sequence from Matinee yields Transparent PNGs

When rendering a movie out as a PNG sequence, the PNGs are all rendered with Transparency and require the addition of a Black layer before the frame can be viewed as in the Matinee.

Went back and tested in 4.5.1 QA Build and 4.6.1 Launcher (2386410)

Also Reproduced in Main Promotable-CL-2493094

1. Open Maintee Fight Scene
2. Open the Matinee Actor
3. Click Movie in the Toolbar
4. Change the Capture Type to PNG Sequence
5. Click OK

RESULTS: See attached Image, All PNGs Have Transparency

EXPECTED: PNGs should be rendered without transparency OR have a toggle which allows for rendering without transparency
