Right now if we have a full 32 gig card and have ten training videos, we have to put the entire card in each of those training videos folders. That takes 32gig and makes its 320 gig. So we want to take the footage and organize it on our hard drives for editing at a later time. Hope that helps clarify what we are looking to do.
Thanks for the clarification. My 2p:
For dog training videos, I would shoot everything on AVCHD 24Mbps - forget ProRes, if you're concerned about storage costs. 320 GBs for 10 videos worth of rushes doesn't seem outlandishly excessive - you just need to work out your sweet-spot for speed of retrieval vs cost. You've had some very valid suggestions so far in this thread.
Another alternative is to dedicate and write off 2 x 32 GB card for each video title - run them as dual slots (parallel recording on both cards) and put the cards into different physical locations afterwards, clearly labelled with the video title. SDHC cards are cheap - treat them like a tape that sits on the shelf and doesn't get re-used. Just make sure you're backing up a disk image of your SDHC card/s to 1 other place, to give you peace of mind.
Ben.
