Tony,
Thanks. The video was informative, but perhaps I asked the wrong question.
I made a video. After shooting, I realized I have a product placement issue: There's a company logo on someones jacket that I need to blur out. The jacket (and attached logo) move throughout the frame.
I used to be a video game programmer back in the mid-80's, and I'm pretty comfortable with pixel-by-pixel editing, so my first instinct was to simply edit the video frame by frame and change the pixels. No dice - PowerDirector doesn't seem to allow this, nor can I find any other software that lets me do this.
Next I thought I'd use a PIP object to cover the logo. However, trying to make a PIP object follow a semi-randomly-moving logo around the screen is proving to be quite difficult. When I finally succeeded in getting the motion correct, the end result still looked bad because it was essentially a mono-color block in the middle of my video.
Any suggestions on how to achieve my real goal: Removing a moving logo from a video?
Thanks!
Howie
