I'm using After Effects CS5 and I rotoscoped several one-frame-duration brush strokes on a piece of footage (.mov, H264) yesterday. They worked fine, but today they aren't showing up. The brush strokes show up on the layer, but not in the composition, and I've toggled the visibility switch to no avail.
Any idea what could be wrong here?
Could be something with your media cache.... Flush it from the prefs. Other than that check for graphics dispaly issues with OpenGL.
