Selur's Little Message Board

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!

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:

Code:
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. Sad

Frustrating! Thanks for the confirmation though Big Grin
