variable frame rate repair / Blend.. & smooth motion (madVR)

Fabulist
Why you ask about variable frame rate? Are you watching anime?
I recommend do not use madVR's smooth motion and SVP's blend frames options if you really want to get smooth motion effect with SVP.

Is there any difference for you, if you use only madVR Smooth motion without SVP active?
What exactly do you mean with "Low Artefact Settings"? Do you use SVP at "M2" (wich is almost (Actually only 1 out of 5 frames are interpolated ones) identical to switch off SVP) or something?

Fabulist
whether I should use both or either (assuming I have to use one)

use madVR's one only

Fabulist
will it cause any side-effects leaving it constantly on?
No. You can leave it enable forever.
If "variable framerate repair" enabled then it use farmedoubling or source framerate on VFR parts. It depends on current framerate and screen refreshrate.
If "variable framerate repair" disabled then it show OSD message and continue to make smooth video with wrong output framerate. It can lead to video delays and stutter.
In both cases when framerate becomes constant (CFR) SVP turns to new right smooth factor to make output framerate the same as screen refreshrate.

Not with the original question.  Just wondered why Frameinterpolation alone doesnt give a satisfying result and forces someone to fall back to an inferior (less effective but also much less hardware intensive) way of smoothing motions with some kind of fake-interpolation.
I personaly would have thought, stuff like madVR smooth motion or SVPs own one are just there for people whos hardware cant afford true frame interpolation or high FPS one. (say, real interpolation from 24 to 48 and then faking it (madVR or SVPs own one) from 48 to 60.

So I thought, maybe the SVP settings could be improved.

But what was the saying in homeopathy? "He, who heals, is right." You feel better with it. So its fine.

As I said, if you think it works, then its fine.
Its just that I prefer to use ONE anti depression pill brand at a time and not swallow 5 different brands of it, at once, it might cause unforeseen problems beeing used together.
Or 7 installing 7 different viruskiller softwares on one mashine, just to make sure.

Forgove me, but 3 different frame interpolation softwares in a row (SVP, madVR and your TVs), sounds strange to me.
Specially if you have SVP settings to "Frame rate". Whats the "Blend to screenrefreshrate" suposed to do in that case? Because say its 60Hz, SVP renders 24 to 60 frames. And then the blender is suposed to blend 60 frames to 60 frames?
It would be something different if SVP would have set to: "double frame rate". Then the blender would at least have something to do by blending 48 into 60.

Yeah. Thats why I said "Fake interpolation" before.

The question remains, if blending frames to a screen refreshrate does actually anything if SVP already does real motion interpolation to screen refresh rate.

Because we are talking here about:
SVP turns 24 into screenrefreshrate, then madVR turns screenrefreshrate into screenrefreshrate and the TVs blending option turns screenrefreshrate once more into screenrefreshrate.

Hm ok.
But woulnt it be better if SVP does the 120 FPS instead of using interpolated (artefact distorted!) frames as source material for another interpolating? Or doesnt the connection support 120FPS?

I dont own a TV. Specially not one with interpolation. I own a Laptop with 120Hz screen and a Projector with 120Hz and use "to screen refresh rate" and the OSD on the projection says: 119,9999 whatever FPS.

Just my thoughts about this? (interpolated frame as source = not ideal)
