Selur's Little Message Board - Video 8 PAL capture/upscale

Pages: 1 2 3

I'm trying to QTGMC and upscale a PAL capture from Video 8 footage filmed back in the 1990s. However, there seems to be a strange faint horizontal lines texture over the entire image which looks worse when upscaled.

Any suggestions?

it's an artifact due to deinterlacing (fixes: bottom field first)

try the top field first

Only had a quick look.
Switching to tff seems wrong (if you are bobbing).
My first try would be setting 'Preset' to 'Custom', enable 'EZDenoise' and set it to something like 4 or higher. (you can set the base preset to Fast)

Thanks for the suggestion. However, when I change QTGMC to "Custom" and set EZdenoise, I'm unable to get a preview window to open.

Strangely using basically the same script:

scriptPath = 'i:/Hybrid/64bit/vsscripts'

sys.path.insert(0, os.path.abspath(scriptPath))

here works fine.

Does the Vapoursynth Preview show an error?

When I select preview, nothing happens at all. If I de-select the EZDenoise option then preview works fine. I'll try re-launching Hybrid.

Still no luck after relaunching Hybrid. Sad

Can you create and share a debug output of you trying to open the Vapoursynth Preview?

Debug output.

Strange, send you a link to my latest dev version, does this also happen with that version?

Sadly same thing. I will try on my Mac.
