I am shooting on a dsr 450 in progressive. But when I edit on FCP I get really bad jagged lines. I thought I had all the right settings, but I guess not. Any ideas?

Could it be that you're just used to seeing HD content and now you're working with SD again?

There's so many things it could be, but since you didn't post what sequence presets you're working with, where you're seeing the jaggies (on the FCP viewer or externally) and whether it's on import or after being encoded out again... need more details, man!

nah. 95% percent of my work is SD. Wish it were the other way around!

I can see it on the fcp screens and on an external crt monitor. I have lived with it for about 6 months but I am wondering if it really is normal.

field dominance is set to none.

it's on import and output.

Impossible to tell without seeing it - can you post either a screen grab or export a freeze frame?
