One thing to check is that it's not judder from a frame rate mismatch or dodgy motion smoothing. Usually if something is noticeably jarring, it's judder rather than frame rate.
It can be notoriously difficult to get these settings to do what you want on most TVs. For me, I always want "no motion smoothing but with automatic dejuddering enabled", which can be almost impossible, or even impossible in the case of some Samsung TVs.
Worse, some device/app combinations seem to just introduce their own judder. For example BBC iPlayer is awful for judder and stuttering, and Amazon Prime on Android TV seems to struggle with some shows sometimes. Android TV is a bit janky in general. Apple+ on Apple TV is always perfect.
What I normally do to conclusively check for judder is I use the slow motion video on my phone to record at 1/8th to look for duplicated frames or other weirdness.
Interestingly, I believe some amount of subtle panning judder is actually created by cinematic filming. Convention is to use a 180 degree shutter, which means each frame only has half the expected motion blur. 180 degrees is usually the best for 24Hz, but it can make certain types of panning shot look a bit unnatural IMO.
- willis936 4y agoThe issue is that fast pixel response time does not fix a slow refresh rate. Now if you strobe the image then you have a good solution, but most all content is sub 60 Hz and strobing at such low rates is a real headache. Pretty much the only option that can work is temporal interpolation. That's a comparatively huge can of worms. https://blurbusters.com/blur-busters-law-amazing-journey-to-future-1000hz-displays-with-blurfree-sample-and-hold/ https://blurbusters.com/blur-busters-law-amazing-journey-to-...
- pjc50 4y agoHaving watched a number of (old, uploaded) films on Youtube on my TV I've noticed that there can be really serious judder - you don't need a phone to see a frame skip/duplication in a pan, it jumps out and is impossible to not see. I've not done enough investigation to see if this is a defect in the original transfers (have they done a bad 24->30) or if it's the TV trying to force it.
