Combining two video sources to accrue detail

Author

Does someone have a strategy for or list of softwares to use to accomplish this?

I’ve seen laserdisc rips that mention “This has been captured 5 times, then averaged to reduce dot crawl and noise.”

I’m wondering how to go about this “averaging”, with perhaps more disparate sources. I’ve got an episode of X-Men The Animated Series in PAL and NTSC. After syncing the video to 24fps and matching up the progressive frames, I wonder if some details could be produced, while also reducing MPEG-2 artifacts, combing and coloured noise.

I use Photoshop, which allow to stretch the videos so they can fit perfectly.

Frame by frame? Good luck! 😄

No, I’m not insane 😃 !
You can treat full movie sequences as smart objects in Photoshop.

Dunno how much it would take to merge two sources (or average/median more) using photoshop, but with avisynth the encode time is pretty fast (from real time with old PC up to 4/5 times with newer ones)

Actually, if you don’t overuse filters and effects (such as unsharp, color levels, noise reduction by color layer aso), rendering is pretty fast in Photoshop CC 2017.

Anyway, I’m just saying that I use Photoshop, but I totally agree that AVISynth is a powerful tool!

Thanks all! hah. if I can replicate the PaNup process with Avisynth (on a VMware install, however) I’d go that route.

Since I’d use the original NTSC audio and re-sync the language tracks from the PAL discs, I suppose it’s a matter of getting the sources synced at 24fps first. What’s the slickest way to get that done? Shot by shot as an image sequence?

I usually do this:

  • convert PAL 25fps to 23.976fps (or 24fps, in those rare cases), tempo and/or pitch (whichever is needed)
  • synch PAL video to 23.976fps (24fps) source; audio would follow, of course

Sounds good! Fingers crossed I can sync the audio in sections with pluraleyes once I’ve got the videos decimated to the same 23.976 frame rate.

Are you talking about 29.97fps source, right?

yea the NTSC version of the episode, as well as the 25fps pal version.

On an unrelated project but similar note, I’m wondering if this is overlay method is possible to colorize the b&w section in Kill Bill Vol 1. using the 480p Japanese DVD.

Someone has already done that with Kill Bill. Don’t remember who, but there’s a BD50 sized MKV of the “Whole Bloody Affair” edit on blutopia that used that guy’s color restoration of Vol. 1 - at work now so I can’t check to tell you who made it, though.

Ah, cancel that then. I bet it’s on the spleen.

I don’t think so but can’t check at the moment. There’s a thread for it on fanres in the completed projects section, someone in there can probably get you a link.

I’m not 100% sure it contains any of the other extra Japan-only bits, though, just the House of Blue Leaves fight in color with the rest being the US version.
