Hopefully I'm allowed to post this here. You may have noticed, if you've seen any of my whinging about streaming services leaving all of their content filmised even if it was originally aired in 50/60fps interlaced, that I'm awfully picky when it comes to frame rates.
For a long time, I've been digitising my DVDs and using Handbrake to deinterlace and transcode everything into 50fps progressive. Only recently, however, I've noticed an issue. I wish I noticed this years ago when I started doing this thing, but better late than never, I suppose.
It's only noticeable on something with constant motion, but my output file seems to be dropping/skipping frames and causing a juddery effect. I couldn't think of anywhere better to upload it, but I've attached a WeTransfer link that contains a few seconds of a Stanley Baxter special featuring a Nationwide graphic spinning around - we.tl . You'll hopefully notice that every half second or so, the spinning skips/judders. It's also very noticeable during any scrolling end credits, where it looks like the credits jump a couple of frames every half second or so.
I've tried both Decomb and Yadif with every combination of preset (except EEDI2 because I'll be dead by the time I finish encoding) as well as trying peak framerate and constant framerate, and changing the overall quality of the video. I've also tried using Same as Source for framerate and that just gives me a 25fps output. I've also tried to Google this issue with all sorts of different wordings and can't seem to find a solid solution.
I don't suppose anybody here might be able to help me please?
