Command for image sequence

[PeterPedro]

Hello, so it's working great with videos but when I try to interpolate additional frames in a sequence of images it doesn't seem to work, it could be me not understanding the command line but this is what I noticed, according to the documentation page http://slowmovideo.granjow.net/docs.html the command should be:

> /usr/local/bin/slowmoRenderer -target images /root/timelapse/interpolated/%1.jpg -input images ??? /root/timelapse/source_images/ -slowfactor .2 -start :start -end :end -interpolation twoway2 -size orig

But the command seem to be wrong maybe? Because -target images should be something like %1.jpg /root/timelapse/interpolated/ instead.

And then -input images I'm not sure if I should just leave it like ??? and it automatically detects the image name sequence or should I do something like imagename??.jpg

So I have tried multiple commands but when it seems to work I get this errors and I don't know what I'm doing wrong.

I'm running it on Windows WSL Ubuntu, that's why I only use the command line, any help would be greatly appreciated.
