Need help with a little VFX ask

CP. Doh! I got my wires completely crossed on this one. I removed the girl walking right to left in the background. Why I thought it was her I have no idea. Not to worry. It's years since I've needed to do a Roto like this, so the exercise was not in vain. Refreshed the old gray matter!

Chris,
I'm gonna request access as well - just because I'm curious about your workflow and "sibling roto cloning"... don't believe I'm familiar with that term.

Mark, you will be, as I've replied. It's just using frames in proximity, before and after, that don't contain the object that needs removal. I do it by exporting a TIFF image sequence from the timeline. Using the closest frames without the target and painting an alpha key through the target frame to reveal the closest background frame where there is no object. Once the person or object has been removed, the new still image sequence is saved and re-imported to the timeline and rendered out as whatever. As an example, the last frame in CP's sequence has the waitress in the background standing to the right of the man standing at the end of the table. You could use the closest frame where she isn't appearing next to the standing man to Roto her out of that last frame where she is standing next to him. Hence, the name sibling frames.

Going back, Quantel Paintbox and Harriette along with Pixel Power's dedicated Collage graphics units used to just capture a sequence of video and allow you to key and paint out frame by frame along their timelines by just nominating foreground and background frames. Pretty quick way to do it. Just painting out the target area. As you painted the key, it appeared as a fine transparent red mask over your target area. If your target area was red, then you could choose a different color for the Alpha key paint mask, so you could see exactly where you were painting.
