My first choice would be some method of frame-by-frame pixel-by-pixel editing, but I can't find any free video editing software to do this (and since I bought PowerDirector I don't want to have to buy another app just for this one feature).
My next choice was to use a PD7 PIP object to obscure it. However, this has two problems: (1) The logo moves around the screen, and it's very difficult with PD7 to match the motion of the PIP with the motion of the logo it's trying to obscure. (2) Even when I can solve #1, the end result looks fairly bad because it's essentially a single-color block that moves around the video.
Any suggestions? (Re-shooting the scenes is not an option.)
Thanks!
