Topic: Why some 4k videos lag while others don't?

I'm trying to do real-time frame rate conversion on youtube videos from 4k 24/60fps to 4k 165fps with mpv, and I notice the result is very choppy for some videos while others are perfectly smooth.

Sample video 1 (4k 60fps)

Sample video 2 (4k 24fps)

Sample 2 does the frame rate conversion to 4k 165fps perfectly fine, but it's not the case for sample 1. Why is that?

My setup is 3080 and 10900k so hardware shouldn't be the issue here, and I have read the entire wiki for proper settings with no resolve. How do you fix it?

Re: Why some 4k videos lag while others don't?

I've downloaded both videos.
First video has 60 fps. And it has only 30 different frames per second. You can look at video from time 3:02 in pause mode frame by frame. Every second frame is a double
So, to get smooth video you need to remove each odd frame first.
