Deinterlacing Weirdness

[Spottedfeather]

I'm trying to deinterlace a video ,but I'm a bit confused. The video is a movie I ripped from dvd. When I played it on my laptop, I saw that it was interlaced. So, in VLC, I turned on deinterlacing and Blend mode. This fixed it just about perfectly. But when I put the video on my desktop computer, it was of course interlaced. So I did just what I did on my laptop. I turned on deinterlace in VLC and blend mode....and while that fixed the black horizontal lines that come with interlaced video, there is now this weird...banding when objects in the movie are moving up and down. This is what it looks like...

I know that this can happen when you pause a video even if it was deinterlaced...I think. I'm not too knowlegable on this subject. All I know is that when the video is moving, I still notice this.

Can anything be done ? Could I deinterlace it through Handbrake or something ?

In VLC try 'Deinterlace ON' and 'Deinterlace mode Yadif (2x)'.
If it doesn't help upload a few seconds of your video.

the pictures I posted IS with deinterlace on and Yadif 2X. And I don't know how to post a few seconds of the video. I wish there was some way I could just send you the whole movie....

Use Avidemix, open the movie, use the A and B buttons on the time line to set the in and out points
Save it as mkv ( the default)

I think I figured it out. But I saved it as mp4, because that's what the file is. The funny thing is that the quality of the video is both better and worse. the weird banding is gone with played through Avidmux, but the interlace lines are there...no matter what mode I use to watch the clip in VLC.

I'm giving up at this point. Maybe it will play fine if I put the movie on a usb stick and watch it through my PS4....

Make sure you use Video>Copy and Audio>Copy when you give us a snippet. The new snipped file shouldn't look any different to the original.

AVIDemux should look like this (Output format "MP4 Muxer"):

There's something odd about the MP4 you've posted above. Stepping through it, one can see a PPPII pattern (progressive x 3 frames followed by 2 interlaced frames), as if it was Telecined. But it is a cartoon, so I wouldn't have thought it would be. Anyway, applying the IVTC filter in VDub clears one of the interlaced frames but not the other, so then it's PPPPI.

Have to wait for an expert, but I'm sure it can be completely fixed.

Telecined source resized vertically without IVTC and encoded as progressive?
The vertical size of 418 and the VFR is certainly not from a valid DVD rip.

Edit: Here an attempt of a fix (still some ugly frames towards the end):

I wish this was something I could do. I guess I just have to hope that my dvd won't crap out on me....as it is literally impossible to find as it's not sold anymore.

I just don't get it. I can watch with VLC player on my laptop and the movie plays perfectly with not interlacing. But when I watch on my desktop, with VLC and the same settings as when I watch on my laptop...well....you've seen what it looks like.

I wish I could get it to look like that on my end. And it IS a valid dvd rip. I ripped it myself. This movie is impossible to find. In the last decade or so since I bought it, it's not sold anywhere I can find and in a decade, I have only seen one single copy on ebay.

Unless I'm misunderstanding what you mean by valid...

[davexnet]

Perhaps post a section from one of the original VOB files. You can use Avidemux,
set "output format" to mpeg-ps muxer

It is not. Just check the parameters of your posted video and you'll see why

I've seen them, but I have no idea what you're talking about. How is it not valid ? I put the dvd in the drive and ripped it to my computer....unless you mean something different than what I mean when I say rip...

I didn't have any VOB files, whatever those are. I just copied the movie from the disk to my computer...unless I'm doing it wrong. I can try ripping it again......if I can figure out how to use Avidmux. I just tried to save a video with it and it didn't work. I'm probably using it wrong, though. what should I rip the dvd with ?

What program did you use and what content was created on your HDD (or SSD) ?
Did you get a video_ts folder?

- DVD is mpeg2 in a .VOB container, resolution 720x480 for NTSC, framerate fix 29.97fps (59.94 fields per second), audio typically AC3 ....
- Your "Rip" is mpeg4 (AVC) in .mp4 container, resolution 720x416, variable framerate, audio AAC.
Frankly your "DVD rip" is crap. Probably your ripping tool/process messed it up badly.
