Hi Tom,

Sorry for the delay in this, but it took me a while to clear out the cobwebs in the 844/X part of my brain.

You wrote: "The QT files are made using FCP's current sequence settings."

Your answer likely lies in there. What are those settings? If memory serves correctly, 844/X media is lower field first for NTSC and upper field first for PAL. This is on thing to look at.

Another concern is frame size. 844/X media is 720x486. If you're coming out from FCP at any other frame size with an interlaced image and you do NOT de-interlace before bringing it into 844/X, you will introduce "weirdness" in the image because the interlaced lines of video get "shuffled" around and don't line up where they belong.

I know there's a lot to digest in there. Let me know if you need me to clarify.

~Wick
