Soozie,
24p (not 24pa) from that camera is 29.97. You will probably need to shoot 24pa and capture with advanced pulldown removal to get what you are looking for. I have that camera and HATE 24p regular. The 30p gives a much cleaner look IMO. But if you can’t reshoot, you might try a smart deinterlacer such as revisioneffects Fields Kit.
Or check out Dave’s suggestion of the Nattress filters. BTW, you ARE viewing this on a proper NTSC monitor aren’t you? Can’t judge this in the canvas.
Have a wonderful day.
