Not related to Sora but, I have been looking for / hoping for an AI powered motion tracking solver. I've used Blender and Mocha in AE and both still require quite a bit of manual intervention, even in very simple scenes.

I saw some promnise with the Segment Anything model but I haven't seen anyone yet turn it into a motion solver. In fact I'm not sure if can do that at all. It may be that we need to use an AI algorithm to translate the video into a more simple rendition (colored dots representing the original motion) that can then be tracked more traditionally.

You should look at this Google paper (came out a few days ago):
