I'm part of an up and coming International broadcaster and pretty soon we'll be among the many corporations moving to a complete tapeless environment. We have material from the past 20 years that is sitting on Betacam SP, DvCam and HDCAM that we've decided to back-up using 'APPLE PRO RES 422(LT)' as the best compromise between storage space and quality preservation (any thoughts welcome on whether this is the best solution).
For the not-so important material... things we may or may-not use in the future; I've been thinking of archiving them in h.264 to save even more space. I would like to ask the International community if this is a wise thing to do. Would conversion of ProRes 422(LT) to h.264 and back lose significant amounts of quality? Or is there a better option out there? Thank you to everyone in advance.
Not wanting to sound like a broken record about tape-based archival, and it's just a thought, but if you can add an LTO drive to your system, you can archive your raw data at full res and never have to worry about loss of fidelity.
