SD vs HD Comparison

[Alwyn Adkins]

Stan, in no small part because of your fantastic knowledge and willingness to impart it. Thank you.

[Stan Jelavic]

Glad I could help.

Alwyn, can you explain how you achieved the interpolation? Would like to experiment with some of my videos. Did you use NeatVideo for the de-noising?

You got some very nice results!

[Alwyn Adkins]

Fred, I do use NeatVideo a lot of the time, but occasionally it goes mad (eg when clouds are racing by, leaving massive blotches, that DC-3 footage was an example) and I leave it off.

In a nutshell, I'm using AVISynth. Here's my standard cine script:

SetFilterMTMode ("QTGMC", 2)
avisource("I:\Cine\Aerial 11\A11 GS300 DVK ST 720x576 Pt 1 DC3.avi")

ConvertToYV12(interlaced=true)
AssumeTFF()
QTGMC(preset="Fast", EdiThreads=8)
FlipVertical()
SRestore(framerate/3.0) # to 16.667 fps

AssumeFPS(18, true)

z_ConvertFormat(pixel_type="RGBPS", colorspace_op="709:709:709:l=>rgb:709:709:f") # RIFE only works with RGB floats
Rife(gpu_thread=1, model=12, fps_num=50000, fps_den=1000, sc=true, sc_threshold=0.12) # motion interpolate to 30 fps
z_ConvertFormat(pixel_type="YUV420P8", colorspace_op="rgb:709:709:f=>709:709:709:l") # back to YV12

Occasionally, as with NV, RIFE messes up the interpolation (eg motor bike races with super-fast changing backgrounds) so I just comment it out and make the video 18 fps.

Let me know if you need some AVISynth tips! 🤣 Not the easiest thing to set up but once it is, it's pretty simple to run provided you know what filter to use.

[Fred Hess]

Yes, I would like some tips. I don't have any 8mm projects right now but when I do, I will message you for some help. Thanks.

[Alwyn Adkins]

No worries Fred, let me know.

[Stan Jelavic]

Interpolation can also be done in daVinci Resolve.

Interpolation without Speed Change

Interlacing is a fundamental method of displaying video, not an artifact. If you "burn in" the jaggies by incorrectly processing it, then it becomes an artifact.

VDub will capture interlaced video if that is what it is fed.

What AI can do

(ps: I have to cut off the kids image because AI did not allow it)





I am just thinkin in the future when AI become our daily lives even for movie transfer can be done with AI to get much better results.

What AI can do

I don't want to appear blunt, but the bottom two, of the man and the headstone, are plainly totally different videos. They aren't even close! You've been conned.

Yes I knew... I was the one who made that AI image. I was just thinking in the future.. in a galaxy far, far away ... where we can give our 8mm print to AI and AI create new image (hence new film) by interpreting the available pictures. Therefor, we can still enjoy our destroyed, faded, heavily scratched print.

[Stan Jelavic]

That is very interesting. Thanks for sharing. So the future AI would look at the scene and re-render it. The scene would be a new scene of high quality but very similar content. Even the people could be re-rendered but would look like the same people just much better image quality.

Yes that what I was imagining. Of course today's AI is just like Windows 95 when first time released, and we are now with Windows 11... very much advanced and faster.

The AI result I made was based on one blurry frame. So AI could not realy recognize the face of that man with blue shirt. Imagine what AI can do if it was given 18 frames a second, surely there are so much information that can be processed/used there. Once AI gets one clear and steady frame of that man, it will be kept by AI for his other acts/moves.

The same case with the headstone, it was created from that same blurry image
AI interpreted what was written there where some writting was correct i.e "Joseph" (although "Z" was read as an "S") but the family name was made by guessing. But once there is a clear image to read correctly his family name that info will be kept for other frames.

In a galaxy far, far away... I was imagining this can be done in real time. So we are projecting 8mm, which is read 18 frames in advance, and 1 second later (processed through a super fast computer) AI project the same film but without scratch, fade, out of focus, blurry and shaking image.

[Stan Jelavic]

It may be available soon considering the growth of AI. Me personally, I prefer that old film look but the new AI techniques are definitely interesting and fun to experiment with.

I do remember in 1990s coloring a B/W film was a sophisticated and expensive techniques. It would cost hundred thousands dollars to finish one F/L. Now that techniques available through (almost) free software...

What was the downside of private (amateur) 8mm films is camera shaking or moving left-right so fast, not to mention 18 fps that created jittery images, now it can be fixed through AI by interpreting it.

[Fred Hess]

An interesting conversation. When I first glanced at the image comparison I thought you were some kind of miracle worker! After looking more closely I realized that there are too many "wrongs" with what AI is capable of now. But at the same time, the possibilities are quite exciting. Like Stan, I want the film to look like film, but if AI could fix jitter issues, color issues, smoothness issues, grainy issues, focus issues, etc., it would surely be fun to play with! Imagine capturing film in real time and letting AI fix any problem to produce stunning results. Hopefully we're on a collision course with that far far away galaxy.
