It isn’t necessarily bad, it’s just an old way to handle low bandwidth. It sucks when video editing, but aside from when we see them when pausing (like your images), it’s very rare we actually notice (from personal experience, at least).
It can be noticeable during regular playback on a modern display, under the right conditions. Anime is one of those due to the high contrast in the picture.
It was also weird to pause an interlaced video on VHS and watch it alternate between frames. Any objects in motion would jump back and forth.
Ahh to be young(er), lots of old TV and media was in ntsc and pal format for broadcast, so it’s interlaced cause bandwidth and storage media cost (you only need to refresh half the crt each pass). There used to be so many threads on doom 9 on the best pipeline for virtualdub(mod) to deintelace and make progressive encodes to divx etc
Actually, interlaced video in NTSC signal was because the NTSC signal was what we used on old school televisions. An old school televisions used an interlaced scan to display the images. Displayed half the image in one scan and then another display the other one and it displayed both of them so fast it appeared to be one image. That’s why TV screens flicker.
Not exactly. It’s true that interlaced signals are good at low bandwidth, but the televisions themselves had an interlaced scan picture, so that’s the main reason why NTSC is broadcast interlaced. For the televisions themselves. When we moved away from analog video to digital video, even television signals in the United States began to transition to a progressive scan, especially when we moved to HD and HDTVs

Ah, I see. I just read the Wikipedia entry on interlaced video and learned that it’s called “combing”.
I was actually just continuously taking a lot of images until the combing was visible. Didn’t pause. ^^
Hail
mpv. It does an AMAZING job at deinterlacing, as an other commenter just taught me. No more combing. :)Ahh to be young(er), lots of old TV and media was in ntsc and pal format for broadcast, so it’s interlaced cause bandwidth and storage media cost (you only need to refresh half the crt each pass).

We are saying the same thing aren’t we?
