If you are editing 24p then I assume you are not
editing in an HDV set-up?
Depending on sequence settings….
You will need to:
1.) De-interlace the 60i footage.
2.) Use Cinema tools to conform the 29.97 de-interlaced file
to 23.98.
Dedicated plug-ins like Magic Bullitt will do this
conversion better but for the sake of time try the
2 steps above.
