canon pulldown

Can anybody tell me what canon is talking about when they talk about their different pulldown options in 24f mode? I'm confused about whether the image is layed to tape as some sort of interlace format or not. If it is just layed to tape as progressive frames, what is the pull down for? Why would you need a pulldown that can extract the original 24 frames if the 24 frames aren't ever converted to interlace anyway? Bottom line, is there any way to edit 60i footage and 24f footage from the H1 without converting one of them? Thanks a lot!

There is no pulldown when the camera records in HD. It's 24 individual frames recorded to tape. In SD the camera records 24f, adds pulldown, and records 29.97 to tape. To mix HD 24f and 60i in the same timeline would require some manipulation, I'm curious myself as to how to conform 24f to play in a 29.97 timeline. Anyone tried it?

If I am not mistaken there are two options in recording 24F (or 24P).

There is an option to have it recorded as 24 progressive un-interlaced frames which would be edited solely for straight to film output.

Or you can choose to film with a 3:2 pulldown, which converts the 24 frames into 23.976 fps by slowing the video down by 0.1%, then doubles up on fields every 4 frames to come up with 29.97fps to conform to TV standards. This format is meant for projects that will be seen on television. If you ever decide you want it to transferred to film, there is a process which is called Reverse Telecine which will then interpret the interlaced fields to recreate full 24 frames.

If you choose 3:2 pulldown (which most people do when filming on these cameras) you automatically capture and edit onto a 29.97 timeline.
