Fixing a telecined video that has been upscaled. Partially solved.

[LaserBones]

I'm trying to fix a music video that was telecined and then upscaled. Below is the current script I'm using as TFM left a lot of artifacts. It's still far from perfect. Is there a better way to solve this? Is it even possible?

DebilinearResizeMT(640,480)
vinverse()
QTGMC(InputType=2)
srestore(omode=5)

Try something like
a. Descale
b. AssumeTFF + Deinterlace with QTGMC (not InputType=2)
c. KillerSpots or SpotLess
d. MCTemporalDenoise

This works pretty well at restoring the original film frames:

LSMASHVideoSource("Mac Demarco - Very Spooky.mp4") 
AssumeTFF()
DeBicubicResizeMT(640, 480)
TFM()
TDecimate()

Follow up with the rest of your cleanup.

Your script doesn't show TFM/TDecimate. How exactly did you do the inverse telecine? If you use TFM/TDecimate properly (you need to use both), and if standard telecine was used, the result should be perfect.

You need to post a few seconds of the original, showing lots of movement, so the telecine pattern can be examined. Trying to patch things up after the IVTC has been screwed up is a waste of time.
