Are xvids or divx files interlaced or progressive?

I've tried to get my head around this & tried searching, but gotten no definitive answer.
Are avi's interlaced or progressive? When I rip my dvds using AutoGK, it reports the dvd as 720x480 NTSC, so that's interlaced. I would imagine that I'd have to apply 2:3 pulldown (or something like that) during encoding to get a progressive avi, so therefor avi's are usually interlaced, at least NTSC. Am I on the right track?

No. Divx and Xvid AVI files are almost always progressive.

Most NTSC DVD movies contain 23.976 fps progressive MPEG2 data that is marked for 3:2 pulldown. The DVD player creates the 59.94 fields per second interlaced video as it plays the DVD. If you rip the VOB files you'll have 23.976 fps progressive VOB files.

Hi-

No, that's NTSC, as opposed to PAL.

All the AVIs that AutoGK creates will be Progressive.

Edit: junkmalle beat me to it. Hi junkmalle.

Thanks for clearing that up. It can be hard to figure out sometimes.

MPEG-4 specs allow for interlaced encoding though and both XviD and DivX support it.
