[HELP] Vapoursynth job never finishing

[qrtrqrtrqrtrqrtr]

Hey, I need help with interpolating 30FPS videos into 60FPS.
My hybrid version is "Hybrid 2020.06.21.1".

I've read a few guides on how to interpolate videos, and I've tried giving it a shot a few times.
The main issue I'm coming acorss comes with the Synths.
AVISYNTH / Gives me an error that "{filename}.stats was not created!"
VAPOURSYNTH / Starts exporting, but the job's progress goes above 100%. It's even gotten to 10000%.

I don't know what to do.

Please tell me if I've made a mistake / posted in the wrong forum. I am prone to making stupid assumptions/decisions.

I don't know what to do.

And I don't know what you are doing.

Please, read the 'Infos needed to fix&reproduce bugs,..'-sticky before you post about a problem.

Also if you read beginning the log you screenshotted log you posted you would have read:

This log is only intended for user information.
It should not be part of a bug/problem report!!

so it's not really a surprise that the screenshot is more an annoyance than anything else.

I get the same issue. eg trying to convert 30fps to 60fps with Filtering -> Vapoursynth -> Other -> Frame Interpolation -> Interframe/SVP

The encoding reaches remaining time 0:00:00 but just continues without completing, with the estimate file size going down and down. 

was working fine in the previous version (apart from the Red Border issue)

Video: x264
Audio: Passthrough
x264 profile: High / 4.2
Encoding mode: specific filesize/bitrate (2 pass),  fast 1st pass, bitrate 1500

Vapoursynth: 
Frame Interpolation: Interframe / SVP
FPS: 60

I'll send you a link to my current dev version via PM to see whether it is fixed in that version if not, create a debug output of the job processing.
