I have copied the post below in order to start a Vegas oriented discussion of this topic.
"Of course historically, we know media manger was for both Vegas and ACID; hence the confusion about where to go for answers.
For me, MM is not sufficient for Vegas so replacement is the best option. NOTE This is a huge hole in the Vegas workflow that makes long form projects very cumbersome. If I still have MAGIX' ear, please ensure you allow "manual sort order" ala Adobe Bridge & PPro - this makes it possible to rough out a sequence of clips BEFORE dragging them to the timeline. Panning back and forth on a timeline is a real hassle when you have hundreds of clips. True metadata tagging (again, like Bridge) would also be hugely beneficial. I believe this is the kind of feature that would truly play to Vegas' strengths as a great editor.
For ACID, it definitely needs a way to search for instruments, keys, tempo, etc. - but I will post that in the other forum. THANKS!"
Question: what else is needed for dealing with long form projects with hundreds / thousands of clips? (Please: let's not talk about bugs; lets focus on needed features.)
Manual sorting,XMP metadata, Fast thumbnails, Scrubbing ? Tabbed timelines?
