Creating Super Tight Junk Mattes
This has been a great technique for me, but I often run into this: the auto-trace will cut off a section of the intended matte, usually something that doesn't move much, like a standing person's legs. The mask on the first frame is good, but after that the mask ends abruptly at some unknown edge.

Any ideas? I've fiddled around and gotten it to work, but I couldn't pin down what specifically did it. Other times, nothing doing.
