I'm trying to figure out how to isolate (mask) and pixelate a person's face to hide their identity, without pixelating the entire frame. I just can't figure out how to do it. Any help would be greatly appreciated.
Masking part of a video, even a moving target isn't as hard as it sounds, at least not with Vegas Video. The important part is the keyframing if you want to be precise and only mask a small portion of a frame is to set frequent points to keep the mask aligned if the target moves around a lot. There should be several threads, I, others wrote more details on this in the past.
