If you use video game footage, capture at whatever the highest frame rate the game/capture source allows, then have the editing program interpret the footage as 23.97/24fps. This will make it look slow-motion. Then speed it up and use optical flow. That should help get rid of some of the frame rate issues.
+1. I would also say that the capture should be done on a next-gen PC graphics card (or PS5 or Xbox Series X) with all of Battlefront II’s textures, film grain, ambient occlusion (etc…) maxed out (if possible. Does PS5 or XBox have a ray tracing patch for this game??).
In addition to my eyes immediately noticing the framerate being weird, the black values are very different in the game footage (I think a couple people have already chimed in with making it have more contrast, and darkening shadows).
The last major problem for me, (which possibly can’t be remedied) is that the textures on the various rock faces around the cave look spotty or low-res in certain areas, especially on the right side of the image. This rock looks so SMOOTH and CLEAN compared to other physical “rock” (styrene or otherwise) we catch glimpses of in Ajan Kloss scenes.
So, obviously I am real iffy on it, but I absolutely love the idea of even 2 seconds for the audience to breathe being added here.
