De-Interlace, 24p, and FCP

Good morning.

I recently shot a little footage of my daughter in 24p. I captured it into a 29.97 time line in FCP. Upon playback in the Canvas I noticed what I assume to be interlace lines in her movement. I applied a de-interlace filter and the lines disappeared.

My question is: Does FCP not automatically de-interlace 24p footage when it captures it? Even more fundamentally, should FCP have to de-interlace it since it's not interlaced in the first place?

Why would you even see interlaced lines in progressive footage? Is this because of the 29.97 time line?

When I de-interlaced I chose the upper (odd) fields. Does it matter- upper or lower- when using this filter for 24p footage?

Cheers,

John

There will be interlacing when editing 24p in a 29.97 timeline. Do not De-Interlace the footage. You lose half of your resolution that way.

If you want to work with the native progressive frames, then you need to remove the pulldown. For 24p (not 24pA), you can do this in Cinema Tools.
 
I sincerely appreciate your time and comments.

Alaska, regarding the NoahK article: to capture at 29.97 I would just setup for DV NTSC capture, I assume. But then, how would I get a 23.98 time line to take advantage of the 2:3:3:2 pulldown?
