Mike Seymour:

The basic problem is two-fold. Firstly, camera footage with valuable metadata gets transcoded and in the process the metadata is lost, and second, there is no standard for non-encoded metadata. Not even a standard printed form – until today.

There are lot of use for camera data. Most of the time you don't have it or nobody knows where it went. The DPX files have been striped of the data and the PA has no idea what the heck your talking about. I hope this helps.
