Are there any means add the blackframes via GPU (shader) ?

Obviously we CAN do this but I'm still not really convinced it's useful for anyone except you.

Old discussion but with OLED having problems with motion blur/judder BFI might be a nice addition to SVP, just as an option pleople can switch on or off.

Test on 60Hz screen with low motion blur (for example CRT or BenQ Z series) :
- You can compare a native 60fps@60Hz  video (1-2ms motion blur / No double Image effect  / Low Flicker / and smooth) and a video 30fps@60Hz (1-2ms motion blur / dramatic Double Image effect  / Low Flicker / and not smooth). This is the equivalent of blurbusters "Frame Rate Compare" tests.
- You can also compare with 30fps+1BFI@60Hz video (1-2ms motion blur / No double Image effect / Very High Flicker / and smooth). 30fps@60Hz vs 30fps+1BFI@60Hz is the equivalent of blurbusters "Black Frame Insertion" test.

Test on 60Hz screen with motion blur (most of LCD) :
- You can compare a native 60fps@60Hz  video (16.7ms motion blur / No double Image effect / No Flicker / and smooth) and a video 30fps@60Hz (33.3ms motion blur / No double Image effect / No Flicker / and smooth).
- You can also compare with 30fps+1BFI@60Hz video (16.7ms motion blur / No Double Image effect / High Flicker / and smooth).

Test on 120Hz screen with low motion blur (for example CRT or All LCD with BenQ blur reduction / LightBoost / ULMB) :
-You can compare a Native 120fps@120Hz video (1-2ms motion blur / No double Image effect / No Flicker / and smooth) to a video 60fps@120Hz (1-2ms motion blur / Visible double Image effect / No Flicker / and not completely smooth) and a video 30fps@120Hz (1-2ms motion blur / Dramatic quadruple Image effect / No Flicker / and not smooth). This is the equivalent of blurbusters "Frame Rate Compare" tests.
- You can also compare to the 60fps+1BFI@120Hz video (1-2ms motion blur / No double Image effect / Low Flicker / and smooth). 60fps@120Hz vs 60fps+1BFI@120Hz is the equivalent of blurbusters "Black Frame Insertion" test with two UFOs. 30fps@120Hz vs 30fps+3BFI@120Hz is the equivalent of blurbusters "Black Frame Insertion" test  with four UFOs.

Test on 120Hz screen with motion blur (LCD 120-144Hz With No Motion Blur Reduction) :
- You can compare a Native 120fps@120Hz video (8.3ms motion blur / No Double Image effect / No Flicker / and smooth) to a video 60fps@120Hz (16.7ms motion blur / No Double Image effect / No Flicker / and smooth) and a video 30fps@120Hz (33.3ms motion blur / No Double Image effect / No Flicker / and smooth).
- You can also compare the 60fps+1BFI@120Hz video (8.3ms motion blur / No Double Image effect / No Flicker / and smooth). And also compare the 30fps+3BFI@120Hz video (8.3ms motion blur / No Double Image effect / High Flicker / and smooth).

The 60fps video was obtained by accelerating (x2.5) of the original 24fps video.
The 30fps video was obtained by selecting one frame on 2 of the 60fps video.
The 120fps video was obtained by interpolating (SVP-x2) of the 60fps video.

Funny that with a CRT u complain about motion blur, u should try a LCD for real motion blur big_smile, but CRT with age has slower response and bigger trail from used phosphor, can it be that problem?

In my opinion you do not read or watch the videos !

the CRT screens do not have motion blur, Idem for LightBoost/ULMB/BENQ Blur Reduction/Turbo 240 screens....

But all these screens are victim of double image effect: if you are watching a film (24 to 50 fps) you see this effect !
Look at the test : http://www.testufo.com/#test=blackframe … qualizer=1

Good if you do not see a diference, is that my eyes are too sensitive ...

Take it easy 

I was still using a CRT 2 years ago and using SVP already. But after 10 years of heavy use the screen was no longer bright and color were washed out so after long reading about different models I opted for a dell u2311h, which are not considered to be too bad in motion blur. First day of use I was O_O because of motion blur. I never really worked with a LCD so was a big shock the first days, even looking at the mouse pointer was hard. Almost returned it but kept it after all for other advantages and no real other all around better screen in market, so I think I can tell the difference 

But what u call double image effect are the sample and hold problem on LCD screens, and it gets all blurry when u add motion blur and some overshooting from RTC, and I don't remember ever seen that problem with my old CRT. And CRT do have motion blur, just check a white square, or round, going across the screen on different speeds and u'll tell me. And it gets worse when phosphor coat gets depleted. But since they are very fast compared to LCD, beam just hit the point for a few nanoseconds, and phosphor usually emits lights for a ms or so, we can say it's virtually motion blur free.

But it's strange that u have a problem similar to the s&h problem on LCD, might be some sync problem causing some stuttering otherwise I don't see what can be the cause. For more deep test u might try pixperan, and see if u have any problem. BTW to see if the problem is more motion blur or s&h problem u can wave ur hand in front of ur eyes and spread ur fingers a little bit for adjustments. Manual black frame insertion  . For example in readability test I can get way higher. But I don't think it will do any difference with a CRT 

No need a roll of film  ... just use home numeric projector ... for example SONY HW50ES/VW80/VW90/VW200/VW500/VW1000 has black frame insertion ...

Optoma GT720/GT750/GT760 DLP Projectors has black frame insertion ...

we're very lucky we don't have a roll of film

Maybe it's time to get a new screen    Only problem is they are almost all TN, but there's a recent one from eizo with a va panel that looks very interesting.

The same 2x faster (original 48fps)

The interpolated (SVP FI 2x 48fps)

SVP settings

On my screen I see double-image effect on this 3 files ("original 24fps"/"original 48fps"/"interpolated (SVP FI - 2x - 48fps)") ...

BFI :
96fps (original 48fps + 1 BlackFrameInsertion) :
http://e-nautia.com/vanden/disk/Publiqu … omex2).mkv

144fps (original 48fps (Doubled) + 1 BlackFrameInsertion) :
https://e-nautia.com/vanden/disk/Publiq … omex2).mkv

144fps (original 48fps + 2 BlackFrameInsertion) :
http://e-nautia.com/vanden/disk/Publiqu … omex2).mkv

96fps (SVP FI 2x 48fps + 1 BlackFrameInsertion) :
http://e-nautia.com/vanden/disk/Publiqu … VP-FI).mkv

- On my screen "96fps (original 48fps + 1 BlackFrameInsertion)" remove completly the double-image effect ... But the brightness is divided by two and there is a little flicker (CRT).

- Same with "96fps (SVP FI 2x 48fps + 1 BlackFrameInsertion)" but this less clear because some artifact are visible.

- "144fps (original 48fps (Doubled) + 1 BlackFrameInsertion) " only 1/3 of brightness are lost and double-image effect is reduced (but visible) and there are no flicker.

- "144fps (original 48fps + 2 BlackFrameInsertion) " remove completly the double-image effect ... But the brightness is divided by 2/3 and there is a little flicker (CRT).

Note :
It's possible to completly remove the double-image effect on "original 24fps" by inserting 3BF (No Frame Interpolation) : 96fps (original 24fps + 3 BlackFrameInsertion) but flicker is unbearable !!

Here extracted videos.

note:
on previous videos, the written frames rates must be multiplied by 2 !
I made the capture @ 48fps and 60fps and doubled the frame rate when remux

but I do not think there was a problem with the tests, the 3 tests "compare frame rate" I see the same effect ... I see this efect also on film (when the text moves horizontally or vertically) ...
For example it is clearly visible on the beginning of the French film "Home" (about 30 sec) ... if you want i can share this passage.

1. Open file C:\Program Files (x86)\SVP\AVS\MSmoothFps.avs in notepad.
2. Add line to the end of file:

3. Close and save
4. In SVP profile window choose Target frame rate: To screen refreshrate / 2

You will get 48 fps at your 96 Hz monitor. You will see how ugly video looks.
