I am a complete novice when it comes to this sort of thing , but VLC media player has a deinterlace function that can be recorded from the player ,I used it while watching an early dvd release of BladeRunner ,which was sourced from a laserdisc release and could see the interlacing artifacts on it ,so I applied deinterlace in VLC and it worked well , I could no longer see the artifacts in the video . VLC is a free open source media player and a powerful tool that can play just about any video file you throw at it .Here are the steps to deinerlace and record on it…

Open the video in VLC.
Apply the deinterlacing filter. You can find this in the video settings.
Go to “View” -> “Options” (or “Tools” -> “Options” depending on your VLC version).
In the “Output” section, choose your desired recording format and location.
Click the “Record” button (usually a red square).
The video will be recorded with the deinterlacing filter applied.

I hope this helps in some way .

I wish more people would respond to the how to requests in this forum .Over the past year or so I’ve seen 0 replies to a lot of questions asked here. There used to be a lot more engagement ,and that’s a shame , I find many of the topics interesting to read . Anyway , good luck with your project !
