I have inherited a quicktime file that had deinterlacing artifacts all over the place, that any normal, man-made deinterlacer will not fix.
On closer inspection (using nattress G Detect Cadence, thank you Graham), it seems that the interlacing cadence actually changes throughout each shot of the clip, not just within the clip itself.
The work originated on film, was transferred to miniDV, then edited on AVID. All I have is a quicktime file of the edited clip.
My suspicion is that whoever edited this first had a bad transfer, then paid no attention to setting up their sequence to assure that the pulldown and cadence of interlaced fields was correct.
I was hoping I could get some comments on this from folks to see if there was anyway to rescue the clip.
thx mucho,
