How to deinterlace this video properly?

[coolgit]

Here is the 14 seconds clip of Babylon 5 ep 1.



I for the life of me can't get it done.

Some people have done it but i can't find any instruction.

This guy did something but haven't a clue what. https://www.modeemi.fi/~leopold/Baby...ransfer.html#8

When the scene goes upwards there is jumping back and forth.

frame by frame u-up; ju- jump up; d-down

uuuujudud uuuujudud uuuujudud pattern. Sometimes a bit different.

It's top-field-first and If you QTGMC() you get a mix of clear and blended frames but no backward movement. That implies a frame rate conversion. Either from an NTSC source or just as part of the production. I recommend you post a shot with a medium speed horizontal panning shot from a live action (not CGI, and not the intro sequence) portion of the show for easier analysis.

Mpeg2Source("14.d2v") 
QTGMC()

Done QTGMC and others but to no avail. Live action isn't an issue, it's the cgi part. Frame by frame of your file is no differences to mine, blurry, you can see the bad mismatch frames.

It should look like this file. Someone did it but use NTSC and mine is PAL.

NTSC version is better. Use SelectEven() on that NTSC version and frames are basically correct. The framing of the shot is also different than your version


Your version is blended, and more conversions have been applied as jagabo pointed out. There is too much blending per frame to "undo" using normal methods. You can try some deblurring / deconvolution kernals, but most are for single image

The following seems to do good things by getting rid of all the blends and drops. However, since it converts to 30 fps progressive, you may have to do things to rematch the audio. Remove the Separatefields() at the end to see the final, progressive video. The Separatefields() command simply lets you see if there are any blended fields left. I have uploaded short clips from both the separatedfields version as well as the version with that removed.

Here's the separatedfield version:

And here is the progressive full-frame 30 fps version:

loadPlugin("c:\Program Files\AviSynth 2.5\plugins\TIVTC.dll")
loadplugin("C:\Program Files\AviSynth 2.5\plugins\MVTools\mvtools2.dll")
loadPlugin("C:\Program Files\AviSynth 2.5\plugins\Srestore\mt_masktools-25.dll")
Import("C:\Program Files\AviSynth 2.5\plugins\Srestore\srestore.avs")

source=AVISource("E:\fs.avi").KillAudio().converttoYV12(interlaced=true).AssumeTFF()
bob(source,-0.2,0.6)
output=srestore(frate=30, omode=6)
return output.separatefields()
