> One minute you are saying that I'm seeing garbage frames with IC.

you said you have "very sharp cut" with MVs, while it's not that sharp with IC
meaning you saw frame repeating with MVs and some kind of "soft" mixing with IC
dunno how I supposed to understand this in opposite way

now we figured that it's exactly opposite - "sharp cut" with IC and soft mixing with MVs, thank godness big_smile
and more, we also figured that MVs gives different results for different frame sizes, at least for 720p and others, which wasn't so expected by me, and I need to look into it

> Is there anything we can do to increase NVOF and SVP algorithms strength

yep
smooth.scene.limits.scene
smooth.scene.limits.blocks

the bad thing is that values that work good with resizing to 720p doesn't seems to work with 1080p and 4K

> IC is properly processing that scene.

with a threshold value <=15
making a lot of false SC detections in other scenes

> The only "garbage" Rife frames are with SVOP and NVOF which explains why I didn't like what I saw.

but you said the opposite thing - "With both NVOF and SVP this is a very sharp and jarring cut" big_smile

> He says he sees Rife.jpg with IC

This isn't what I'm saying.
I'm saying you'll see either
1. repeated frame 1 - when SC detected + "Repeat frame", regardless of the method used (IC or MVs)
2. blended frame 1 and frame 2 - when SC detected + "Blend adjacent frames",  regardless of the method used (IC or MVs)
3. some garbage mixed by RIFE - when SC missed, regardless of the method used (IC or MVs)

And I'm also saying that MVs are more accurate than IC, regardless of the "threshold" value.

> For some reason SVP smoothness does not work properly with them now.

this is the cost of non-blinking
it has to repeat frame when DV data changes, which may happen at random places

it's clearly a scene change and SVP do everything right - see f1.jpg before SC and f2.jpg after SC

> what you call "garbage" might simply the AI doing it's job1

see attached rife.jpg
for the 3rd time - if you OK with this - then OK, "SC = disabled" is right for you
and I'll continue thinking that proper SC detection is a must for every frame interpolation algorithm

there's no way to "over-react"
if it see the SC it repeats the frame before SC or blends two frames
if it miss the SC then you'll see something mixed by RIFE -> which is your case with IC
that's it

So MVs see the scene change while IC doesn't, and still it's "better". OK then big_smile

Can you provide the timestamp? I have that in high quality and I can test tomorrow.

3.06 and 3.16 the ribbons of the creature , maybe I misinterpreted and its something else.Thanks for taking the time.

smooth.scene.limits.scene = 8000;

> SVP motion has at least a couple of clear and repeatable stutters for certain scenes that IC does not.

meaning
1. it's a false positive SC, right? in which case you'd better share a sample with the problem... there're a lot of variables to adjust there.
2. you really prefer "RIFE-generated "garbage" frames" over frame repeating at a false-positive SC big_smile

probably you just prefer RIFE-generated "garbage" frames over repeated or blended ones

>I still think that image comparison work the best

to be "the best" it must give less false positive scene changes, and less missed scene changes
which is not true

apparently, DV blinking _was_ fixed, but it seems that now, with a processing logic changed for "motion vectors scene change", the blinking is back, but for a different reason big_smile and it's a different kind of blinking now...

still the latest "0.38" changes were necessary, but not enough
