Re: [Avid-L2] Sort of OT: Weird Pix240 Problem

This is all guesswork...

First guess: the Pix is recording PsF which will carry an Interlaced
signal just the same as a Progressive signal but the file will be
flagged incorrectly.
Second Guess: the field order is inverted.
Third guess: you won't be able to fix this in MC because it's reading
the progressive flag.

If the above guesses are correct, then you have to somehow get the file
re-flagged as Interlaced, and maybe invert the field order while you're
at it. I know how I'd fix this in DS but don't know what tools you have
at your disposal.

Tony
