Winbert: As I alluded to, storage is still an issue but not quite as bad as your post would imply and getting better all the time. If you were to archive in a completely uncompressed format, then I will accept your numbers, but there is no reason to do that to preserve the quality. There are loss-less compression algorithms where every pixel can be reproduced exactly as they were. Think about the way zip files typically work as a non-video example.

Tom, when you are talking ZIP or any other compressed files then you are out of the basic principle of archiving.

Professional archiving is to store the closest possible to the original, if you cannot have the original.

We cannot say that easy to archive William Shakespeare's manuscripts...just photocopy them (xerox) and store them in several places. Yes, you can still read the manuscript but the meaning of archiving is to keep the hidden information that probably is not yet seen now.

Star Wars The Force Awakens is 4K. We have just restored a B/W 1960s film to achieve the 4K quality. There are 150,000 frames in this film and to get this 4K quality, it took 2 hours for the archivist to restore every single frame, resulting 53GB for each frame. So the total for one 4K of this movie is 12TB!!.

12TB = 12,000 GB or eqv with 100 desktop computers

The hard work of our archivists is now can be watched through a single DVD, but surely our archivists will not keep that DVD in their storage, but the true 12TB files.

Pls remember our movie is B/W and mono.....Star Wars The Force Awakens is in color and 5.1 surround sound, so the information data stored must be tripled if not quadrupled.

Anyway, this is already out of the original topic.
