Image sequences are difficult to deal with,especially with LTO tape
libraries. Archives commonly use zip in either a compressed or uncompressed
form to alleviate this issue.
It's preferable to have an uncompressed or lossless single file for ease of
use, compatibility with tape libraries and digital asset management systems.
I would prefer to retain the original image sequence but it is not common
practise I'm archives from what I understand,for the reasons outlined above.
