Hi all

What are the Mac app option/s for setting a layer change?
I have a few 2-3h dv files I want to burn to dvd dl and would like to set the layer change.

Also any extra info on:
A quicktime mask on an interlaced dv file and then a 16:9 dv export?

Or use MPEG Streamclip to zoom and save as 16:9 dv?
