“I struggle to see the advantage of uprez’ing the entire clip…”
That’s because you’re not thinking through all of the possibilities. You’re assuming I’m suggesting uprezzing the ENTIRE tape… I’m not. I am only suggesting uprezzing a complete clip (timecode start to stop). That will reduce the amount of time digitized to a more manageable size.
I chuckle at your suggestion that this may only work with “small sized projects”. What you don’t know is that we are regularly using this method on multiple hour long shows, referencing THOUSANDS of hours of media. Our SAN is BIG (over 300+ TBs) and that’s still NOT big enough to go full HD start to finish. Most people who suggest staying at full rez fail to consider the bandwidth required to have a dozen editors pulling 20 streams of multi cam media simultaneously. Even if you have the storage space, the bandwidth requirements will stop you from using the “all HiRez all the time”.
In our case,our acquisition format is XDCAM-HD which makes the uprez process a breeze. It’s faster than real time, so we pay a very small time penalty for digitizing extra media. In a perfect world, I’d definitely try to stay full rez all the time. But we don’t live in a perfect world, and the workflow I’ve suggested is the best compromise between efficiency and cost that we’ve been able to devise.
