Im interested in AI technology that can replace a face in a video for a humorous or creative project. Which tools produce convincing results, especially when the person moves, turns their head, or changes facial expressions?

One of my first attempts with AI photo editing was actually pretty random. I had a portrait of myself from a trip and wanted to place it into another picture just to see how believable the result could become. Rather than learning a complicated editing program, I decided to use https://overchat.ai/image/add-person-to-photo. I uploaded my portrait as the reference and selected a different outdoor image as the scene. Before generating it, I described where I wanted myself positioned and mentioned that I should be standing beside another person already visible in the picture. That seemed to give the editor a much better idea of what I was aiming for. The first result wasn't perfect, mainly because my original photo had a slightly different camera angle, but it was still interesting enough to make me try again. For the second attempt I picked a photo with similar framing, and the difference was obvious. The scale looked more natural and the overall composition made more sense. I also liked that I didn't have to manually remove the background or adjust shadows afterward. Usually, when I edit pictures myself, those little corrections take most of the time. Here I could concentrate more on choosing suitable source images and describing the placement. It ended up being a surprisingly entertaining way to experiment with old photos.
