I’d make sure display rate switching is off - 'cause it’s off here on my TV (different brand, but worth a shot).
Well, we’re trying to correct a problem - not create another one…lol
Nothing odd about it to me - if things play fine the way they are - I don’t change them.
Many years ago I found out what happens when you lock a frame-rate down and the source changes the frame rate on ya when they go to CGI (older Star Treks and such). That cured me.
Since then I’ve used SAS and Variable - and it’s never let me down.
Make some 240 second ‘Previews’ from Handbrake’s Newest Version and drop them in an Other Videos Library - so you can test these things in a shorter time span.
Since we didn’t see the full MediaInfo report for your video (and why not?), I suggest you use the same Handbrake I’m using - not ffmpeg - mirror my settings EXACTLY and make some previews.
… and here are the EXACT SETTINGS I’m using and I’ve just turned out 18 great ones at 25fps - 3 of 5 Seasons of Line of Duty that are being added as we speak with the other 2 seasons in the grinder now:
DVD Section - as these I’m making are 480p, but I churned out 12 HEVC Main 1080p episodes for another 25fps show I did yesterday (and the day before, and before that) - Doc Martins/World On Fire to be exact.
… and we’ll kindly ask @ChuckPa to watch over us so we don’t do anything dumb on ‘Linus’ for ya ('cause I wouldn’t know ‘Linus’ if he jumped up from that little piano bench and bit me)… but carry on until he yells at us…lol
