I wrote a bash script that detects/removes telecine & interlacing to prep DVD rips

It solves a lot of problems that I encountered preparing rips of TV series DVDs for upscaling. Any kind of feedback is welcome, although my skills are pretty limited, so I won’t necessarily be able to follow through. If you want to give it a try, you can find it on github:

I’ve been using ffmpeg -r to drop those extra frames all this time. I suppose some of what you explain in there might be why I’ll get one or two combed frames in a movie. That’s pretty rare though.

Hi @utahjohnnymontana

I believe that you have put a lot of work into solving an issue I’m currently having with DVD Rips (With MakeMKV) that were originally filmed at 23.976 FPS but have been changed to 29.97 for Broadcast or DVD Distribution. I’m wanting to run them through TVAI to change the resolution and clean-up the footage but cannot get it to work as TVAI is recognizing the import as 29.97 and any processing causes the Audio & Video to go out of sync.

That’s where all the work you have done seems to come in (Very Much Appreciated!!). Just wondering if you can point me in the right direction to how I can get started with you’re scripts. I am totally unfamiliar with it and generally prefer to use tools with a GUI. But it appears that there are not a lot of tools around that will do what I’m looking for.

Do you happen to have a step by step guide on how to get started with your scripts?
