Deinterlacing Footage - tom619 - 26.01.2024 Hello, I'm posting as I have some new footage that I am trying to deinterlace. The footage itself appears to be 16mm that has then been transferred to a tape, which has then been further transferred to a digital file. This digital file is 1920x1080 so applying deinterlacing directly does nothing. After a few tests and experiments, I believe that the best thing to do is crop the black borders horizontally by 240 pixels on each side, making it a 4:3 ratio, and then resizing it to 640x480, and then deinterlacing. I'll post versions of both the original digital file, and my resized and deinterlaced version. I was wondering if anyone thinks I can potentially improve the version I have. There is still a bit of residual ghosting and obviously the quality has taken a bit of a hit, so it would be great to know if there is a better version I can make. Thanks! RE: Deinterlacing Footage - Selur - 26.01.2024 Argh,.. Yes, looks like someone unqualified for the job did the digitalization. (in my opinion: Saving interlaced content as progressive without proper deinterlacing and then upscaling, really disqualifies.) About the top: I first thought something like: x = 12 newBottom = core.std.Crop(clip, bottom=clip.height-x) newTop = core.std.Crop(clip, top=x) clip = core.std.StackVertical([newTop, newBottom]) would work, but I overlooked, that the above is from a field before. => yes, simply cropping is probably the easier approach About fixing the deinterlacing: yes, sadly: cropping, resizing (horizontal should be enough), deinterlacing, upscaling again and then trying to get rid of the ghosting somehow is probably the best you can do. Cu Selur RE: Deinterlacing Footage - tom619 - 26.01.2024 Frustrating! Thanks for the confirmation though
