Archive of Broadcast material in h.264???
on Nov 12, 2012 at 3:16:04 pm

Hi all,

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.

kind regards,

Tawqeer

Yes.

Sorry, but serious quality loss when converting between compression codecs is a fact of life.

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.

BRU ... because it's the RESTORE that matters!
