David, need help! shot 60p with a framerate of 48fps..how to get 48fps out ?

Hey David, we just got done shooting a batch of footage, I did not think that I would have a problem getting the 48fps out of the 60, but as it turns out when I Hdlink it gives me what looks like a 60fps avi file with dupe frames in it...what is the method of getting the 48fps out?

thanks a million for an answer as we are on a tight deadline and need to get the 48fps out of the file for some vfx plate work.

;)

48p out of 60p is an HD-SDI capture option within Premiere's capture interface was Prospect HD. So is this MXF file related? HDLink will handle the native P2 modes, with over/undercranking to 24p, but will not handle 48 embedded in 60p. Use yousendit.com, please send me a sample MXF.

THing is, I don't really want to deal with HDSDI if we don't have to, as I don't want the digital->analog->digital conversion...I will upload our ftp with an mxf of the stuff..sorry I did not know I should use 720pn for the 48fps stuff!

named it a .zip it works now. rename the file .mxf when you get it.

ALso I can't capture because our system does not have enough CPU power for 60p, so a working HDlink would be most helpfull! thanks!

Yes that is correct. We are converting all the frames in the MXF file, and honoring the frame rate indicated in the MXF header. So your 48 in 60p is converted "correctly", I'm still going to look for a simple extraction.

Haven't seen any P2 footage before so I hope you will forgive me for taking a look at your download. It's definitely a 59.94fps file but I'm struggling to find the duped frames. I'm moving through the resulting AVI file frame by frame and each frame looks unique...

Are the frames being blended rather than duped? If they were being duped and were at regular intervals, VirtualDub could probably take care of it. If they're blending (and it looks as though they maybe), that can't really be adjusted on the HDLink AVIs as is.
