I need some advice or tutorial example to help me edit this video I have. This is a product video with a host talking about the product, the host missed an important word on part of his script so I need to make his mouth move in the video to fix the issue. This video was shot a several times, so I do have audio clip if the missing word as well as additional footage of videos that the host did read the script correctly, it's just that the best shot I want to use has that missing word mistake. I have been on the web searching for ways to fix this and I see several mouth moving tutorials that's based on still image so they won't work... The current best bet I have in mind is to mask the part of good clip, feather it, and see if that blends in or not, but this video was shot in 1080p, so it seems like it's going to be a little bit hard. I have not tried the method I had in mind because I want to see if anybody's got any better advice?
