Looks pretty nice, am signed up for the beta. Am hopeful this will be useful... it's very frustrating to me how bad the media management capability of FCP7, FCPX, and Premiere are. I thought Prelude would be helpful, but it is useless for this as well.
Adobe says the reason they can't rename clips is due to restrictions in some formats (AVCHD comes to mind). It will be interesting to see how Bulletproof handles this.
It is one thing to ignore the disk space needed for highly compressed video... but data rates are going up....4K, especially RAW, is another story. I like that with REDCINE-X I can at least delete clips.
[edited: thought you could rename clips with redcine-x but apparently not]
