Topic: For certain mpeg2.ts files it only upscales to 50FPS on a 76Hz monitor

e.g. on this upload of a tv show it appears to only go to 50FPS when the monitor is 76Hz:

On every other file it works normally:

I don't know if this might be useful.

A video that plays properly:

A video that goes 50FPS:

I can see the "50FPS" source is interlaced. It then goes on to assume "the file is 50FPS because it's interlaced". Does that mean the software remains practically disabled?

Ah. Great info. I guess it's more complex than I thought.

The video did look already to be 50FPS on "no soft di".

I guess something does it automatically.

Something odd is if that I force software deinterlacing to 50FPS and SVP does not assume that frames are doubled, it does attempt to go to 76FPS, but the video is choppy/has hiccups.

I guess it's normal, and it wouldn't do anything better even if it worked well that way(there would be no more visual info to process+slower) but I thought of mentioning it.

Forced software deinterlacing to 25FPS + SVP not assuming frames are doubled works fine.
