I've been looking into fixing interpolation on videos from some studios like WankitnowVR and DeviantsVR who seem to use frame duplication to go from 30 to 60fps which if I'm not mistaken is utterly pointless and makes the videos feel choppy compared to most these days?
I found an SLR blog post from a while ago 'SexLikeReal Reveals Its Mastering Techniques' and changed the command to this:
ffmpeg -i INPUT.mp4 -vcodec libx265 -acodec copy -crf 18 -filter:v "fps=29.97,minterpolate='fps=59.94:mi_mode=mci:mc_mode=aobmc:me_mode=bidir:vsbmc=1'" -f mp4 -preset:v slow OUTPUT.mp4
It drops every other frame from the input converting it back to 30fps before interpolating it using the method in the article. Is this still the process SLR uses, or is that a trade secret?
I've been having issues with fuzzy/blurry interpolated frames only during dip to black transitions anyone any ideas why this would be?
Blurred Frame - Look at lamp by bed, door frame etc.
Next Frame
Would SLR consider doing better 60fps interpolations on videos that need it as well as the 90/120fps ones that are sometimes done? Or is this just down to the studio?
