It's a speed up of 4%, you won't lose anything other than picture quality (HDCAM < MiniDV) but the pitch of the audio will be 'slightly' higher. Don't worry, here in PAL land we are very used to getting american movies in such a way.
Big question is why are you doing it?
Please post back saying what solved your problem. It could help others, and saying 'thanks' is free!
Thank you Daniel,
This is actually not me but a friend of mine who shot her movie on 35 mm film, has it already on hdcam 24p, and now, for some reasons, wants to transfer it to miniDV in Pal system, to eventually digitize it in to her FCP.
I suggested that she transfers to FCP directly from hdcam in lower res (if she has access to a deck), otherwise i suggested to make sure that the final clips used for offline are at the same frame rate as film (just to be sure). But since I don't want to give her wrong advice, I wanted to hear from you guys also.
