The station tech I know is still on holidays. When he gets back I'll ask him what he thinks of all this.

Vesku,

Reading this thread, and other similar threads on P-view, and other similar threads on dpreview - I can't determine a) what question you are REALLY asking and b) what ultimate answer to image quality you're truly looking for.

You keep asking questions about plasma televisions, and LCD monitors, and camera hacks, and so on and so on. You seem to not do much editing nor color correction, and use video application-specific settings (such as level clamp removals) to attain the result you wish to have - so that you can shoot hours of footage, and playback direct-to-screen... and yet the forums you visit are mostly populated by people who are not normally that sort of user. Their answers to your questions are generally not what you're wanting, because it's usually this: "technique X is better because of post operation Z", and you respond "well, I don't do anything in post".

At times it seems that many of your questions are better suited to a forum for television enthusiasts, than content creators...

To put in another way: I play drums. In drummer forums, we spent lots of time discussing equipment, technique, inspiration. We don't spend much time at all discussing LP vs Cassette vs CD, which one sounds best for recreating a particular Neil Peart beat. For those things, there are audiophile forums on other websites.

I'm left to wonder, as I said in the beginning - what ultimate knowledge are you seeking, exactly? Are you wondering which camera to purchase, which setting to use, or which television to purchase - or something else entirely? Or are you just sort of bored, and posting questions for the sake of starting some random discussion?

I'm not trying to be rude. If it's just boredom, that's fine (i guess), but I think a lot of respondants (here and elsewhere) are starting to tire of the same vague question ad infinitum. If you're after some more specific knowledge... perhaps it's time to target that question, and then move on to some other video-related interest.

@Vitaliy

Open any serious monitors/TV tests and check response times measured for all colors/shades.

Here are typical reviews of modern LCD TVs with motion improvement features.

http://www.hdtvtest.co.uk/news/samsung-ue40f6400-201305042929.htm

When it came to motion processing... ...the F6400 still managed to return 1080 lines from the horizontally scrolling chart in the FPD Benchmark test disc (up from 300 if [Motion Plus] was disabled), providing a welcome boost to the clarity of moving objects in fast-action sports content such as football.

http://www.hdtvtest.co.uk/news/philips-46pfl9707-201304042732.htm

The 46in 9707 manages to cleanly draw up to about 350 lines of motion natively. This raises to a full 1080 with [Perfect Natural Motion] enabled on any setting (even the lowest).

http://www.hdtvtest.co.uk/news/samsung-ue55f8000-201303212755.htm?page=Performance

As with previous Samsung LED LCDs, the Samsung UE55F8000 can show all 1080 lines in a scrolling resolution test chart, provided that the [Motion Plus] system is engaged. With this feature off, you’ll see the usual LCD motion performance, which delivers just 300 lines worth of clear details. That’s enough for 24fps movies to appear without much in the way of discernable blur, but fast, high motion content like televised sports will still appear with some

This motion test is made visually by looking horizontal panning bars with eyes.

So LCD visual motion resolution:

-1080 lines with motion improvement feature

-300 lines without motion improvement feature

Almost every Plasma TVs show 1080 lines too in theirs tests.

CONCLUSION ABOUT USING LCD COMPUTER MONITOR:

It is hard to see any motion related IQ things like benefits of sharp motion with 60P, artefacts, etc. For example it is hard to see superiority of GH3 MOV artefact free motion rendering because it is impossible to even see artefacts with AVCHD with 300lines of resolution. It is also not optimal to watch hand held videos because every little movement of camera drops resolution to 300lines. It is not so big issue with 24P because motion is very soft anyway but people cant figure why it is better to shoot 60P because they dont see better sharpness in motion, only smoother motion. Videos are so best to watch with a modern TV set.

So you prefer incomplete sources and semi educated discussions? And how are these going to help you exactly? Cognitive systems and interactive media (along with their many sub-subjects) is a fascinating field, but you need proper approach, not guesstimating..Edit: Researching involves reading, searching and then evaluating and choosing your sources, otherwise it's just googling..

OK I make a new offtopic topic. Sorry for trouble.

I dont think it is offtopic.

Most of the people are video oriented here. How can issue about monitor video motion quality be offtopic. Why doing lots of IQ improvement in video shooting and then not caring how to watch videos? Obviously not many are interested about this matter. But on the other hand not many here are not shooting 60P and want to enjoy sharp and fluid motion in video.

So you say this phenomenom is not real. I am confused because to me it is very clear. One more example.

http://www.testufo.com/#test=eyetracking&pattern=lines1

When watching ufo in the center, vertical lines are sharp. When following moving ufo same vertical sharp lines becomes soft due to eye/brain, not response time. Plasma screen has no this kind of softening because of image "strobing".

@Vitaliy_Kiselev

I was surprised when I figured this issue. It is a little confusing but it is documented well and reasonably and my empiric tests proofs it.

I suggest that you think this again:

How can you explain video softening in LCD screen when individual frames are tack sharp but seeing motion is soft?

@Vitaliy_Kiselev

From that Wikipedia page:

"Motion blur has been a more severe problem for LCD displays, due to their sample-and-hold nature.[3] Even in situations when pixel response time is very short, motion blur remains a problem because their pixels remain lit, unlike CRT or PLASMA phosphors that merely flash briefly. Reducing the time an LCD pixel is lit, can be accomplished via turning off the backlight for part of a refresh.[4] This reduces motion blur due to eye tracking by decreasing the time the backlight is on. In addition, strobed backlights can also be combined together with motion interpolation to reduce eye-tracking based motion blur."

My LCD has 5ms response time and it shows sharp individual frames in motion. But because pixels remain the same every 1/60th second eye/brain gets confused because it predicts motion but the frame is still the same all that 1/60s. A friend took photo burst (400fps) with Nikon V1 of LCD screen motion test. Result is that this cheap LCD showed sharp frames during test but seeing the motion was still soft.

He writes:

" I recorded this "Response time test - ghosting" test with Nikon V1 with 400 fps video mode. It shows that my computer monitor running at 60Hz is showing the moving pattern keeping sharp. Still it gets blurry in my eyes if I try to follow it. I checked it in video editor and it seems like it takes 7,5 ms for a line to change from black to white and 20 ms from white to black. This is affecting only the first and last bar in the pattern since other bars in the middle keeps stable time as seen in the video.

I guess the picture gets blurry due to slowness and "memory" phenomenon of eye/brain."

@Vitaliy_Kiselev

My ideas are obviously not getting many fans in this forum :)

How can you explain video softening in normal LCD screen? Individual frames are tack sharp but seeing motion is soft.

What do you think why biggest TV makers use all rapid scanning backlight technology in LCD TVs? Is it cheaper to make or is it just a marketing trick?

What does your eyes say?

@Vitaliy_Kiselev

Thanks for interest for this matter.

Lets forget CRTs. This issue is with computer LCDs. I think that "sample and hold display technology that causes retinal blurring" may be new to you too.

Very rapid frame flickering in plasma or very rapid backlight scanning in new LCD TVs is solution for blurred motion. Response time has little meaning in this. This issue is eye/brain related and rapid frame strobing fools brain to get illusion of sharp motion.
