I saw the video yesterday, and the cuts between multiple short scenes made me think it was slop. I clicked away and did not investigate further.

What did it for me, that seperating wall connects through the mirror like it’s just glass, the doors and wall in the reflection just don’t work with the room geometry and where that separating wall would be is in the middle of where you would have to be to get that photo without also being in the reflection, there’s also way too much floor space where from the reflection we should see the corner of a separating wall off to the pedt of the photo, the angle of reflection on the cats face doesn’t match, and there is no sloped angle of reflection even though the mirror is leaning at at least 10 degrees, which would be a very noticeable angle of reflection, we should mostly be seeing upper wall and ceiling in the mirror from the angle the picture is taken from, there shouldn’t be any carpet in the reflection.

When in doubt, examine spacial geometry and angles of reflection and refraction.

Sorry to tell you, this is 100% slop.
