720/24p DVCPro HD into Avid

Hello Folks,
We are working on green screen footage shot 720/24p. We just captured it 20:1 at 30fps into our Avid Composer. I am planning on having it rough out in lowrez and then recaptured at HighRez and sent to a graphics person as a 24p uncompressed HD quicktime.
(I hope there is not a problem going online at a different frame rate!)
My understanding is that the cameras always shoot 30fps and flag the frames that need to be removed to get it to 24p.
Does Avid do this? Or should the DVCPro HD deck be setup to playback 24 removing the flagged frames and then capture 24 into AVID?
We have an a Adrenaline as well. Any advantage of using that?

I would always recommend editing offline at the same frame rate as the online... you will find yourself in EDL matchback process to get ot the online. As far as capture, yes. Over FireWire Avid will pull the 24 frames as needed. But just to be precise, you will be in a 720p/23.976 project.

Three related questions - as a quick follow-up about using fire-wire to capture DVCpro footage shot with a VariCam. I was in touch with an experienced Avid tech who informs me that there is an option in the Capture window that asks "Preserve all frames" or something like that. If this box is checked, it actually ignores the flags and pulls in all 60 pf/s shot by the VariCam. These frames can be played back as slow motion in a 23.976 project. He says that people pull these frames into AfterFX to create VFR shots in post-production quite often. Questions:
1. What version of Avid Media Composer software is required to create a 720p 23.976fps HD project?
2. Has anyone used this technique successfully?
3. If successful, what is the advantage to flagging frames in-camera for slow-motion? Are there other camera controlled options available that affect the image differently?
Very interested in an answer to this, because I have a show that would benefit from using this technique.

1. For several years now there has been 720p/23.976. I believe starting with v1 MC Adrenaline and v3 or 4 of Xpress Pro.
2. Yes. I have. Keep in mind when capturing flagged frame only that it will be V only.
3. If capturing 23.976 or all 59.94 frames, then the flags are not really needed in the capture process. The 23.976 will play at speed and the 59.94 frames will play back 2.5x slower. The flagged frames are needed when shooting frame rates other than 23.976 or 59.94 such as 32, 48, etc.
