Hi all,
I finally decided to do something about the Monty Python's Flying Circus DVDs I've got.
A long time ago, I got a nice function from scharfis_brain which would get me a progressive 25fps output from the 60i sections (which are originally 50i). The sections which are originally shot on film, can be restored with Restore24(a,b,1250,2997).
This is the function for the video sections:
x=kernelbob(order=1)
#blend two NTSC-fields together (50:50 blend)
a=x.trim(1,0).mergeluma(x,0.5).mergechroma(x,0.5)
#blend three NTSC field together (25:50:25 blend)
b1=x.deleteframe(0).mergeluma(x.duplicateframe(0),0.5).mergechroma(x.duplicateframe(0),0.5)
b=b1.mergeluma(x,0.5).mergechroma(x,0.5)
#concat them
interleave(b,a)
#blindly select them, to get progressive 25 fps
changefps(25)
Now I have two questions:
1) Can the process be automated so that I wouldn't have to search every video and every film section and apply different functions to them?
2) Is there a better method available for treating the video sections? When scharfis_brain gave me that function (in November 2004), there were no working methods for getting the original 50i video back.
Here are two samples, one from a film and one from a video section:
