Many thanks Joris, I undestand a little bit more now.
I already know DXV will play straight foward on resolume, and hey! I don't want to leave it
I've missed the point that HAPinAVFoundation is a developer framework.
So, lets say if I have all my assets on a 'mezzanine' compression to manage common tasks (edit, quicklook, etc), still can transcode those files to DXV on any app wrapped to work over QTkit.
So the only downside on this is the ability to export to third party codecs on common apps, if they get rid off all the qtkit stuff, right?
