Awful results with optical flow. Tips for improving it?

I've been trying some slow-motion recently and I don't know if I'm doing something wrong but my optical flow is working really bad. Everything under 20% gets really blurry and no a sense of slowmo at all.

I've been recording at 60 fps and then playing it at 24.
I use a tripod for the shots and a 50mm 1.8f
Shuttered speed 1/60 (I don't now if this even care when recording)

So... I don't know ...
Any factor to consider when trying to work with optical flow?

Try running the clips through cinema tools.

You don't need optical flow to get from 60 to 24, but maybe if you want to stretch the shot further after you have converted it to playback 600 frames per second at 24 FPS.

Cinema tools first. Then optical flow.
