Like the website….please can you change the Qube Cinema link to http://www.qubecinema.com rather than qubecinema.in.

Thanks

Phil, I do agree with you on this. Anything over 1TB is not really workable with Blu-Ray, tho duel layered 100gig disks go a long way.
I would count anyone doing XDcam (or similar bitrates) can easily get away with Blu-Ray storage sizes. As long as you don;t intent to backup ProRes intermediaries. etc.
That would account for all Wedding producers, and many doco makers. This is the more prolific side of the industry. Any producer from there down, Blu-Ray will probably be fine. Anything more ambitious, like a film or heavy visual effects, 3D, colour grading.. Your data archive gets big fast.

When I was doing a lot of visual effects work, we would have a project grow with all working files to near 1TB for a 30 sec commercial.. But once kulled of all intermediaries, the size would to down to 100-200gig. (Remember its only 30 sec. SD, uncompressed.)
We can derive all the intermediaries, in most cases, from the originals.

This is a reason I am not a big fan of producing ProRes intermediaries. If the video technology is done well, hopefully in QuicktimeX, you shouldn;t need to, even tho its Long Gop. You just need intelligent decoders (With a lot of cache . Should be perceptionally as fast.

I’d like to clarify, that although the manufacturers with a vested interest in Blu-ray all recommended Blu-ray as a backup, it would only be viable for the smallest of projects- those that might fit on one or two Blu-ray 50 GB discs.

For serious production it’s no solution. Can you imagine backing up 6 TB to 50 GB discs? Not a solution for most films or TV shows: fine for prosumer, hobbyist.

LTO is the real long term data solution proved and used by the IT industry and now affordable enough for even small facilities. For the rest RAID 5 or RAID 6 is cheaper and less “messy” than attempting a Blu-ray backup.

I reported, I did not endorse what I reported I think all three companies are wrong for professional markets.
