Interpolate 24fps videos to 60fps in PotPlayer

Download and install the latest AviSynth+ (with vcredist)
https://github.com/AviSynth/AviSynthPlus/releases

Download the latest MvTools
https://github.com/pinterf/mvtools/releases

Extract x64 from the archive (DePan.dll, DePanEstimate.dll, mvtools2.dll) to C:\Program Files (x86)\AviSynth+\plugins64\ (adjust the avs script if avisynth is not installed in this directory)

In PotPlayer:

hi how do i have more than 60fps with this script without any issue??? im have a 165hz monitor with nvidia 3070ti , 16gb ram , cpu 12400f im change num=60 to num=165 but voice not sync with image!!! pls help me, tnx a lot

How can I use this with LAV Video Decoder instead

@captain-k4

I think for the above script, It only doubles th file source fps. that's the best you can get after I test it.

Hey! you are the best, im testing this metod in 2023 with RTX3060, all right! of course this run very well in Windows (i was config your script for sync with my screen 144fps), maybe in some videos audio de-sync but in potplayer you can "resync" on the fly and voila!, great tutorial!

Do you know a similar method for Linux? Thanks!!

this work good for highend pc in 4k
but not work so well in loptop with intel gpu in 4k video
even with increasing the ram to 10240 mb
any solution for me??
my spec lop top : intel i7 1165g7 - intel iris xe share to 8gb - 16gb ram
pls help me tnx

Hi edjdavid, I've just configured this with PotPlayer and the result is shockingly good.

I have a question: I often watch videos at 1.25 or 1.5 speed, so for example 24fps becomes 36fps at 1.5X. The script does not know the playback speed and hence the video becomes 75fps (see attached screenshot). Is it possible to take the current playback speed into account to maintain 60fps even if the playback speed changes?

I edit this script can run to 144fps
Just change the "num=" to target fps

I have a problem
When I use mvtools the video out will decreased to nv12(8bit)
How can I edit to keep 10bit output
thanks

worked, but i want to ask, when using this, my CPU works harder than VGA, how do to make the VGA work optimally and minimize the load on CPU? btw, my VGA is Nvidia RTX. It should be possible, right, with the increasingly advanced technology now?

I could never get this script working right, so I just kept using SVP3 (last free version).
If anyone wants to give it a shot, this is made mainly for 3D movies but it can still be used as a regular player: https://github.com/ThreeDeeJay/PotPlayer3D/releases/latest

Worked for me like a charm. Win11, Nvidia GPU. Managed to lerp 24 fps to 120 fps. Looks awesome on my 120 hz TV)
I used the original script, but had to tweak some parameters in the script to keep performance stable. Because if fps gets unstable - audio quickly gets out of sync with video.

First tweak was to set more memory. I'm not sure if I really used that much, but doesn't hurt for sure.
SetMemoryMax(4096)

Second tweak was suggested by captain-k4. It's much better than hardcode amount of CPUs

Overall I'm very happy that I've discovered that topic. This is super useful. Thanks.

Hello, i dont know where do you write this script guys.
I searched for the file everywhere.
avisynthplus_motion_interp.avs does not exist, svpmanager.ini does not exist, avisynthplus_motion_interp.avs same.
The only useful file I found is ffdshow.avs, I changed the memory in it to 4096 and it still crashes then in the file it changes itself back to 1024.
I cannot see any 2k video, i have 32Gb of RAM on Ryzen 7 5Ghz, and it still crash..
In Pot Player and Classic Player it crash after 2 sec.
Please help
