What is 3:2 pulldown?

What does it do for a video conversion, quality-wise, and when should one use it?

this link will explain it better than i can.

Thanks. I tried really hard to read that, but couldn’t make it past the second paragraph. :o

haha, it’s a bit dry for anyone who doesn’t already understand it. basically, conventional film is shot at 24 fps, while NTSC video is 29.97 fps. to fill in the “missing” frames when converting from film to NTSC video, the 3:2 pulldown flag is enabled. the visual representation in the link (beneath “Telecine to NTSC Video”) will make this easier to understand.

Yeah, I kind of got that. so it would only be used if you had a movie converted to video? But any DVD or capture source would already be NTSC wouldn’t it?

i believe most NTSC dvds are 24 fps with 3:2 pulldown because of their original source. 24 fps with 3:2 pulldown is still considered NTSC. this is better explained under “MPEG-2 and DVD.”
