Hi I just join the DVXuser, Ive been reading stuff in this site for a while now...great stuff thanks a lot to all of you that spend the time here.

I tend to read a lot but i was reading one tread and got all confused with the Progresive thing and interlaced vs not interlaced

I basically been documenting an individual for a few years, started filming with the VX2000 (meaning I have a lot of footage with that camera already) Now I used the 100a, but shoot on 24p planning on mixing the footage Its that ok?

when I edit I use FCP standar DV ntsc timeline...

I just want to be sure that I am doing the correct thing here...

some enlightment would be greatly appreciated.

muchas Gracias

Interlace - standard video displays every other line(odd or even) of a full image (frame) and then displays the other lines on the next update. These are called fields. NTSC does this 60 times a second. That's where 60i comes in. It's 29.97 frames a second. When you capture NTSC video it's captured the same way. You as the viewer don't notice this when played on a standard TV.

Non-interlace or progressive- Each frame image is complete. This is how motion picture cameras work. This is the P at the end of 24p or 30p

You can mix 24p (not 24pa) footage that was captured at 29.97 along with standard video footage (60i) in a 29.97 timeline/sequence. Note that motion will look different. Motion in standard video (60i) looks like video and at 24p looks more filmic.
 
Yes. 24p is 24 progressive (full frame non-interlaced)
Note that when it's captured to camera and played back from a 29.97 editing sequence it will have interlacing (as it should). The orginal frames are pure but to playback on standard video at video speeds some frames are duplicated and interlaced. This is the same as transferring movies to video (and the term adding pulldown).
