Low res/contrast OLD clip

I’m new at this but I have looked at the demos and read the userguide, so I am as familiar as anyone starting out.

My problem is that I have a B/W clip of an old kinescope I am trying to rotoscop with Motor/MochaAE.

The clip is jerky and has little contrast between the character and the background. Is there a better way to do this without having to do a frame by frame?

If you want to see the clip you can go to www.diplo.org/test/jc_2.avi

Any comments, observations or suggestions will be greately appreciated.
