I've read quite a few posts, on a number of threads, on this subject already - but thought it might be useful to bring the collective observations/thoughts/recommendations of those far more knowledgeable than me together in one place...
First off, I make no claims at all in having any expertise whatsoever in this potentially confusing field
Background
I recently took delivery of a Panny TX-55GZ950B to replace my 7-year old GT60B. In short, I am very pleased with my purchase
However, having read excellent views of the 4k HDR version of the BBC's 'Planet Earth II' I purchased a copy and played it from my OPPO 203. Yes, very impressive HDR imagery - but I was somewhat disturbed by what I think is significant judder on fast horizontal panning shots...
A good example can be found in the 'Mountains' episode - starting at about 5:20 for a couple of minutes. The camera pans a group of Ibex running away from a fox, across a cliff face. For me, this results in a rather disturbing juddering effect.... This occurs, with IFC off and at IFC min. I have tried IFC Custom, with Film Smooth set to about 5 - and that seems to tame things somewhat.
But, am I going about this the right way..?
- I am aware that some effects of fast horizontal panning can be down to less than ideal camera technique (but the Beeb?).
- I have no idea whether what I am seeing is actually judder. It could be stutter, or other effects?
- I have read some sources that suggest that, because the panel runs natively at 120Hz - and 24Hz is a whole multiple of that, it should be able to reproduce 24p material without any detrimental effects. Is this a reasonable assertion - what about the capabilities of the rest of the video chain?
- in my case, my video chain, and settings are:
Oppo 203
Video Output Setup > HDR Settings > HDR = Auto, Dolby Vision Processing = TV-led
Video Output Setup > Output Resolution = Auto (have also tried Custom - UHD Auto)
Video Output Setup > De-interlacing Mode = Auto (not relevant to 24p)
Denon X3300W AVR
Video > HDMI Setup > HDMI Passthrough = On (not relevant in this case, I think)
Video > Output Settings > Video Mode = Auto, Video Conversion = On (have also tried Off, but I lose the onscreen menu overlay), i/p Scaler = Off
Video > TV Format > Format = NTSC (the TV can take either PAL or NTSC inputs)
Panasonic TX-55GZ950B
Picture > Option Settings > 4k Pure Direct = Off
Picture > Intelligent Frame Creation > I have tried Off, Min, Custom*
* As the disc is 24p, and therefore assumed to be from a film (rather than video) source, I have found that Custom > Film Smooth = 5 or 6 seems to tame things...
I understand that the Blur setting is intended to address video-sourced (50/60Hz material)?
Better to allow my Oppo to do some of the processing - or should I send the TV a pure original signal? (i.e. is the Oppo better at doing some aspects of processing than the TV)
Am I experiencing Judder - or something else?
Please feel free to tear the above to pieces - I am largely ignorant in these matters
However, if expert members would be kind enough to contribute, I hope that this thread would be very useful to a number of Forum members.
Thanks in advance for your experiences/contributions
