[pm-s]

I was trying to remaster/restore RHCPs "By the way" music video however i stumbled upon this stupid dot crawl. Is there any way I can remove it?

note: its even more visible in some scenes, and video file i have is in .VOD format

AviSynth has lots of dot crawl and rainbow filters. But you'll have to supply a sample of your original MPEG 2 data to see what works best.

I can not see the dot crawl on the youtube video, but I only checked the taxi lights:
It would be a better source, isn't it? It is also in its original 24p on youtube.

You need to supply a sample that has not been reencoded. I believe you can use Mpeg2Cut2 to trim out a short sample from your VOD file. Upload the resulting MPG file to this site.

its compressed af. also entire video has been deinterlaced using 24p method making some 30p scenes jagged

Can you send me your video per pm, so I can see it, just for quality check? Do you think it was shot on 30 fps?

Music videos are often a mix of different frame rates. Some parts are shot on film at 24p, some on video at 30i, titles/effects at 30p or 30i. Then some shots are slowed or sped up by various techniques. The only place they all meet is at 30i or 60p.

I think the only place where 24p and 30fps interlaced or progressive "meet" is 120fps, 3:2 pulldown doesn't count, judder is awful.

For 99 percent of NTSC viewers they meet at 60p on the TV screen. NTSC viewers are used to 3:2 judder and most of them have no idea there's something "wrong" with it. But yes, 120 fps will give the 24p sections an even 5 frames each, the 30p sections 4 frames each, the 60p sections 2 frames each.

according to how it was made segment of dvd, it has been recorded with film cameras in 24p however turning off deinterlacing/detelecining in vlc revelas that some scenes are in 30p too
