Hello.
Since the last update I get the errormessage "Avisynth 2.5 is not suported blabla, use a 2.6 or MT" or something like that.

Yeah. I use this (but rarely) to make 60FPS videos to be watched on my smartphone.
It really is anoying to encode the stuff doing a lots of clicks and then you even need to put in the audio track with another tool.
And with my meanwhile 3 years old Laptop, it takes about 1,5 times as long as the actual video. Like 135 Minutes for a 90 minutes movie. *sigh*
Ridiculous. If one images my smartphone can film in 60FPS... but well, it possibly uses hardware encoding. Hmm.
Check you SPAM folders.
My Key ended up in the spam folder of my email account.

Not always. Maybe currently, but today's top-of-the-line hardware is tomorrow's mainstream.
Yeah maybe, but what I meant with "always" is, "no matter how you fiddle with the settings of the current version of SVP, you will not get rid of artefacts"
"Always" in the sense of "with all existing setting combinations"
Now there is basicly: "get used to it or let it be." 
There will always be problems with the video in fast motion, if you want it smooth.
You only can get used to it.
Most things you could do had been mentioned.
I add this one:
Frames interpolation mode "Adaptive" is theoretically a good, compromise choise.
It switches between Uniform, 1m and 2m while the movie plays, depending on the scene.
It estaminates how badly the frames will interpolate and picks one of these 3 settings.
You could make "adaptive" gear down more agressive. If you want to experiement with that. 
Go to the SVP folder (in a SVP 4, its in the script folder), find override.js
open it in an editor and find:
//smooth.scene.limits.m1 = 1600;
//smooth.scene.limits.m2 = 2800;
//smooth.scene.limits.scene = 4000;
If you lower the first 2, you make "adaptive" gear down from Uniform to 1m and then to 2m more agressive.
EDIT:
Wait... Its said, the new SVP interpolates better then the old one. Means, you could also try that.
Motion vectors precision: the smoothness of smaller movements
Motion vectors grid: the perceived speed of any motion
Its the Motion vectors grid, that controlls the smoothness of smaller motion.
So more small that grid, so smaller motions are smoothed. But it comes on 2 costs: 1. much more processor power is needed. 2. smaller grids increase artefacts (strange things happen on the screen). Thats why 12 was (in the old SVP) considered the best compromise.
All these things exist in the old SVP and are explained there.
There is only one new. The last one. "Width of top coarse level". That has not existed in the old SVP.
In that part for the meshszize (Bewegungsvektornetz)
there are 3 times the same (16 px, Mittel 0) but no say 12 (I have seen screenshots with 12 in it)
Can it be that those 16 are actually.... 16, 14, 12? (last of the "16" is prechosen, so I guess its the 12 one?
Hm.
I want also to know, how and when, it will be possible to free one "slot" again.
I buyed a 3 Computers key (one for my laptop and one for my desktop and one just to make sure ), so I dont need that too soon, but still would like to know. 
Ah.... my was in the damn spam filter.
Hm. Release date is gone.
Does that mean, keys have been sent and my is in SPAM or whereever? Or something else got wrong?
Where is the smoothness settings in SVP4 GUI?
As far as I know, customizing of settings is only possible in the "Pro" version, wich is not released yet. (tomorrow... oh wait, the release date was removed)
Hi.
I watched low resolution material the last days. But today continued with a 1080p stuff and.... my MPC crashed the moment SVP4 sets in.
I know that 1 week ago the same stuff did work with the same settings.
The old 3.x SVP works too. And other resolutions 720p and smaller do work.
What can this be?
EDIT:
Hmm lowering a setting in MAD fixed it. (something I increased over the default... years ago. Render Que. Whyever I did it anyways.
But still. Never had this before and I used that setting since years.
But if you use 60 FPS on a 144 Hz monitor without Free/G-Sync, won't you end up with the hated judder because 60 doesn't divide evenly into 144?
Thats what tools like "Reclock" are invented for.
For those of us that have refresh rates of 120 or 144, SVP 4.0 automatically uses that refresh rate as the max FPS. I think 144 FPS is a bit overkill
Well, not really. I use 120Hz on my Laptop aswell as my Video Projector.
It actually has an advantage over say 60, mainly because with 120FPS ALL original frames are kept. Thats not the case with 60.
If 24FPS is turned into 60, you get 12 original frames and 48 rendered frames. The other 12 original frames are skipped.
But if you turn 24FPS into 120FPS, then you get all 24 original frames in the final video plus 96 rendered ones.
Its always best to multily the FPS by a integer value.
24 FPS are best turned into: 48, 72, 96, 120 or 144 FPS
Most PC monitors are 60hz, so those people would only have 48FPS to chose from if they want all 24 original frames to be kept in the original. But if you have a 120 or 144Hz Monitor, I suggest to use that, if the PC is fast enough to do it.
Of course with 30FPS the list to chose from would be: 60, 90,120, 150....
So, 120FPS are perfect for 24FPS material aswell as 30FPS material.
that one - http://www.svp-team.com/forum/viewtopic.php?id=2648 - "DelayOnPlayStart" ?
Yes, right. Is there something like that in SVP4? (in the full version)
Hi there.
I try SVP4 since some days (and preordered a full version of it. Yeah.... I FINALY recovered my Paypal account.... after 100 problems that prevented me from recovering it....) and suddenly see that reclock does not find a videostream anymore (I thought it did, 2 updates ago. Didnt check if last update worked)
I had these problems with the 3 too (never with 60 FPS, but with lots of content in 120 FPS, wich is the speed I use)
In the 3, I was able to fix it, with something that was said here on the board. (something that made the waiting longer). But there is no such file in SVP4.
I have a question about this.
Is this the number of installations or the number of computers?
What I mean is, if the computer is exchanged with a new one, will I lose 1 slot and need a second one or can that first slot be filled with a new hardware?
Will there be other payment methods than Paypal?
I don't think so
Sigh.
Any porn site is able to offer creditcard payment.
yeah ok, possibly creating porn pays more than creating software. Understood.
Will there be other payment methods than Paypal?
I have a Paypal account, but I never used it (except ONCE, when I wanted to pay with creditcard but it said, yeah pay with cerditcard over paypal... errrrr.... grrr)
Well, the problem is, I lost my password and security phrase for it and the way to get it back is... somewhat anoying to me. 
Besides that I hate paypal just for getting all those pishing mails like: "thank you for buying a space flight for 15 million dollars over your paypal account." stuff.
If 1m and Uniform are the same for non-fractional framerate interpolation ratios, then how does "Adaptive" compare to 1m and Uniform? Does it also only do something for fractional ratios?
Well, Adaptive dynamically switches between Uniform, 1m and 2m (dont know if it actually includes 1,5m) during the movie, based on the estaminated quality of the motion pathes. Its not a mode by itself. My guess is, it doesnt care if 1m looks identical to uniform, it just choses 1m if the quality drops below the treshhold.
Maybe like this?
I wouldnt call it stutter. If I watch a video and there are 2 scenes: first is the whole screen is filled with water (raining or waterfall or other water idk) then the video is smoothed perfectly (it looks so real)
I would even imagine the oposite. Full screen waterfall could (dont know if its the case) be like constant scene change. Strange.
second scene is 2 persons talking to each other and nothing happens except that then video is not smoothed and it's like I didn't use SVP at all (there is only slight smoothing but not noticable)
uh ok. People talking.
Ok, thats definately one of the things where there is very small difference between smoothed and non-smoothed video, thats right. (if one uses the Demo-Mode to compare it. One person talking non-smoothed on the left and a person smoothed on the right)
Ok, the only idea for this is... try if decreasing the "motion vector grid" does improve that.
I do not know if it improves something like that, but in theory it could be the case.
And thats why:
Large motion vector grids detect rough, more global motion to smooth them. But very small, localy limited motions are not smoothed.
Imagine something like... turning a head and blinking the eye. The head turning beeing smoothed but the eyeblink does not get extra frames.
But I really dont know, how small and localy limited a motion must be to drop out of smoothing.
But decreasing that grid (make it finer) will make smaller motions smoothed aswell.
On the bad site, it increases artefacts and does need much more processing power.
Can't SVP creators make a new "frame interpolation mode" that smooths every frame/scene ? Because Uniform is not enough I think.
No. Uniform DOES smooth everything allways. Except if the scene changes. And you can increase the treshhold that recognises a scene change, so you could theoretically force SVP to smooth always, even over scene changes.
It did not help you.
Also I use beginner svp interface because the advanced ones have too many options and I get confused
Oh, I see.
Ok, to try the changed motion grid you need expert mode.
Then it looks like this:
Leave everything alone, "ecxept motion vector grid". Try smaller numbers than the default 12.
Maybe try that "blend" setting aswell. (it helps for the same scenes, that increasing the scene limit helps, but in a different way. By blending frames into each others instead of rendering the motion)
Fanty1972 wrote://smooth.scene.limits.scene = 4000;
I tried increasing it but I didn't see much change, I didn't understand your "description" that well (language barrier I guess)
In most scenes, you will not see the difference.
In scenes like this, people might recognise that SVP apears to stop smoothing with a limit of 4000:
The light situation changes permanently. This causes the whole picture to change all the time.
Increasing that smooth.scene.limits.scene will help in THAT case. (or any other case where massive change in the picture shows up, that SVP falsely interprets as a scene change.
Very typical, like here is, if light sources move or change and by this alter everything else in the picture.
Do I understand it correctly that increase "4000" to "8000" or higher will make it so that the casuel scenes (not the fast moving as you described) will be smoothed? If not, is it possible to do it other way? Thanks
No, it will not help with the problem you described. It only helps in very special kind of scenes. (described above)
I dont know what your problem seems to be. You have a "stutter" effect, in every slow moving scenes you said.
Thats strange. Slow moving/changing things should be easier to smooth than fast moving things.
I wonder if something else is causing that stutter. The video renderer or madVR settings to high.
You COULD try the other things that already have been mentioned, but I am not sure if they help you, if the cause of the stutter is something else.
xDragonking
Btw I'm already using Uniform smoothness with 2x the frame rate (usually at 48fps because movies are 24fps)
Yeah 2x has the lowest artefacts of all possible FPS settings. Just because 50% of the Frames (every second frame) is a original frame and 100% of the original frames are in the final video.
With 60FPS only 20% of the final frames are original frames and only 50% of the source frames are shown in the final video.
If you would have the possibility to show 120FPS, it would be better than 60FPS. Thats 20% original versus 80% rendered aswell (Like 60 FPS) but with 100% of the source frames showed in the final video. (plus of course 2 times as much FPS), so in theory, it only has advances and equals, but no disadvances.
I looked into the .js file and i didnt really understand anything xD
The things I spoke about are these:
So more worse the quality of the motionpathes so higher that number.
In default its:
If motion pathes are worse than 1600, fall back from UNiform to m1
If it becomes worse than 2800, fall back to m2 (dont know how m1.5 is defined)
If its worse than 4000, then assume thats a new scene and just show the next frame (or blend into the next frame if scene blending is activated)
If you watch a video with extreme changes in every frame (like say... a police car passing by and turning whole frames into red and blue shades all the time, or explosions all around in a dark scenario or smoke or fog or whatever changes the entire image all the time.... SVP does not work at all because it assumes the scene is changing once per second or faster.
If you increase that 4000 to say 8000 or higher then such scenes will be smoothed.
Hm. Since you use UNiform, the first two wont affect you, but the third will:
//smooth.scene.limits.m1 = 1600;
//smooth.scene.limits.m2 = 2800;
//smooth.scene.limits.scene = 4000;
There is one thing that Maken1 did not mention, wich makes it more smooth:
"Frame Interpolation Mode" set to "Uniform"
Why? Whats up with that, how does it work and so on:
Default Setting of that is "Automatic", so it looks at the scene (the estaminated quality of the motion pathes if I understand it right) and decides if it can do 2m, 1.5m, 1m or Uniform.
Only if it thinks that the scene is very easy to do and there wont be any worse artefacts it choses "Uniform". Thats possibly the case in camera pans and stuff like that.
If the calculation shows that there might be worse artefacts coming (because the quality of the motion pathes is foretold to be bad) then it goes down with the setting and if the scene is really worse and will be totaly full of artefacts then it picks 2m, wich "feels" almost like non-smoothed (but if you try 2m on a camera pan, you see its better than no SVP at all, but it feels like "no SVP at all", if you dont compare it.)
If artefacts dont bother you but you want the maximum smoothness even in hard to do scenes, pick "Uniform".
In override.js file, opened with a text editor, you can even change, when the "automatic" setting shall fall back to m1 or m2 or at what bad quality of motion pathes is shall assume a scene change (can happen wihtout a real scene change if a police car with changing lights passes by)
Edit:
Possibly Maken means this:
ohh there is one player that always smooth not matter the scene but it cause lots of artifact to can do that.
