If one is using a decent consumer player, could it be possible that you could use filters that might get you close to X0 quality? Not spot on, but close enough to save someone $2,000!

I captured a portion of my ANH Faces LaserDisc and ran the composite signal through a Line TBC / Comb Filter to convert the signal to S-Video before the signal ran into my Hauppauge USB-Live 2. After the IVTC process, I ran the video through AviSynth and did my work from there.

Here’s my current script that seems to do very smart and modest noise removal and sharpening. As you can see, nothing fancy, just one plugin:

AVISource(“LaserDisc.avi”)
ConverttoYV12()
MCTemporalDenoise(settings=“low”)

Results (includes basic levels adjustments):

It removes basic player noise and sharpens what’s left over. To my eye, this doesn’t look all that bad, but it could definitely still use some work. I’m interested to see if anyone knows of any filters that might further make this capture even better.

Here’s my raw IVTC’d clip for your disposal to test for yourselves:
