determining 24p vs 24p advanced footage
Is there any way to tell if your footage was shot in 24p or 24p advanced mode?
I thought I knew my frame rate for certain tapes, but clips that I captured are showing up as needing rendering in places that I would not expect.
To note:
– I am editing in a 23.98 timeline– I captured the 24p adv. footage using the 2:3:3:2 pulldown removal and set up a “test 23:98” sequence.
– I captured the standard 24p footage at DV-NTSC easy set-up, and once I have all of that captured, plan to use Cinema Tools to convert that footage for use on my 23.98 timeline. Warnings about not getting the full data stream were heeded! I set up a test 29.97 sequence.
Some clips are behaving badly, showing up as 29.97 although another clip on the same tape (24padv) came in at 23.98. Also a few clips need rendering on BOTH test sequences, making me think that perhaps something was altered in the middle of the 15-min segment I digitized (which would mean part of it needs to be rendered in each segment).
If there is a way that I can look at my footage, either in my DVX100a or in FCP and determine if it has a 2:3:3:2 cadence (pre-capture) or a 2:3:2:3 cadence, then I will be sure to not capture using the wrong setting.
Many thanks – hope this is not too muddy.

Thanks for that Very Important Information, Dave
I had limited “capture now” to 15 minutes, knowing that I stood a better chance of running into trouble if I had longer clips.
I have done a ton of research about work flows and capture options, marinating myself in information from textbooks and forums like this one and the Apple Support forums.
Until your post, I have never read warnings about capturing large amounts of either 24p or 24p adv footage and am VERY grateful that you shared that info, which make sense as I think about the frame rate cadences and the possibility for error.
Bottom line, there is a lot of conflicting information out there, and most of my editor/filmmaker friends have told me to “just capture the whole tape,” something I was not inclined to do since I on my previous film I logged every tape (100 hours) on VHS window dubs first, and frankly don’t have the storage for capturing every inch of my footage.
I have also read input from “experts” ~ moderators of forums and textbook authors saying it’s better (and easier on your tapes) to capture longer amounts and then go back and log/create subclips. It can be difficult to determine which is the best plan for me, my tapes, my computer, and the amount of storage I can afford.
I do greatly appreciate the information – although I didn’t need the “big boys” comment to be honest. I am amazed that this information isn’t out there on a more consistent basis!

I really don’t know where you are coming from, perhaps you misread my post?
I AM using a deck, a Sony DSR-20. Not sure why you automatically assumed I would not be using a deck.
I DON’T have 24p and 24p advanced footage on the same tape.
I have footage shot in both modes, on SEPARATE tapes.I am not in high school, I am not a big boy or a small boy or actually a boy at all. I have had a film broadcast, won awards, and am trying to capture and log my footage using FCP – planning to work with a professional editor when the time comes.
Your condescension is unnecessary and frankly counter-productive.

clairemp,
I would recommend getting Noah Kadner’s DVD. You can get it at http://www.callboxlive.com. Noah does a great job of clarifying all of this stuff. Its well worth the money.

Thanks Matt- yep it actually is a rather tricky thing to get your head around and we spend a bunch of time going over it on the DVD. You can figure out if footage is 24p or 24pA in two ways- one load a tape into your DVX and switch to VCR mode. Toggle the display button- it will display the shooting mode.
Or open a clip in FCP at 29.97. Step through frame by frame. 24pA has one interlaced frame every 5th frame. 24p has more. You need a monitor to see this clearly. I show how to do this on the DVD as well as a boatload of other stuff. Hope that helps. 🙂
