I wonder if anyone has a recipe for converting mixed 24p/30p (encoded as 30p) content to 60p.

"ffmpeg -vf decimate" removes judder from the 24p parts, but introduces judder into the 30p parts.

I also tried "ffmpeg -vf pullup,dejudder", but that didn't remove judder from the 24p parts. Maybe the pullup filter only works with 60i?
