AE CS6, Roto brush, Chroma Key
I’m using AE CS6 and Windows 7 on an HP, 64 bit computer. I imported an H264, 1929 x 1080 video from PremierPro.
At 5:51 in this Color keying tutorial, (https://tv.adobe.com/watch/learn-after-effects-cs6/color-keying/), the instructor applies the Roto brush. Later, he scrubs the timeline and you can see the Roto brush outline throughout.
When I apply the Roto brush tool, the outline is fine for the first few frames (see left image), then the Roto brush outline becomes a flat line at the bottom of the clip (see right image). Any help would be greatly appreciated. Thank you.

Correction to the above post. The Roto brush outline appears around the perimeter, not just the bottom.
