It took me quite a while to figure out. It involves masking/rotoscoping/green screening just the hands so that it becomes a whole new mp4 layer. Then you place the lighted keys from SM on top of the overhead view and beneath the masked hands in your video editing program. I've tried using After Effects to rotoscope my hands but I couldn't really figure it out. AE itself isn't very intuitive and the performance was terrible and ends up crashing most of the time, even with my beast PC. Thankfully there's a much easier method I discovered. I use a site that makes it easy to isolate the hands. https://app.runwayml.com/ It's free to use though you're limited to 720p quality but I don't think viewers even notice so I don't think its a deal-breaker.Use the green screen function on the hands. Make sure you have proper lighting when you record so that the AI has an easier time tracking the hands. Usually once it manages to track just the hands for a few frames, it's able to keep doing so until the end. If so, let it render and you'll have your mp4. Import it to whatever video editor you use and key out the green.Forgot to mention, when I render the lighted keys from SM, I turn off everything except for the keyboard lights. Meaning no keyboard, a black background, and raising the glow so that you get that nice bloom effect. This way I only need to use a Luma Key (I use Premiere Pro) to get rid of the black. I'm then able to place the mp4 on top of my overhead view without any issues.
