For the life of me I can't figure out how to properly deinterlace this video. Created 2 small clips of it for testing:
118.8MB
26.3MB
These are the same clips, I just resized one down with CRF12 if anyone doesn't want to download larger one.

When I deinterlace it, it doesn't come out smooth. It looks as if a frame is missing.
At first I thought it was 3 clean frames and 2 dirty frames, but looking closer (especially of them walking in) it looks to be maybe all slightly interlaced. Just 2 of the frames are spread more apart, one more than the other.

I captured at 30fps. At 60fps every frame was doubled, so I'm not missing any frames there.

Any smarter folks know what's going on? Thanks.
