SD vs HD Comparison

[Alwyn Adkins]

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

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.

Interpolation can also be done in daVinci Resolve.
