The time has come, VEGAS 20 is finally out!
Check out that File Drop online collaboration, share projects with fellow editors, colorists, fx artists, etc... with the ability for each to leave you notes on the timeline after making their changes... and HSL Curves and new white balance controls in the color grading panel! VST is finally fixed and updated in VEGAS (New VST bridge plus VST 3 support)! There's also a handy automatic project archival system. Plus:
New GL transitions
Transition Progress with animation
Scene Detection creates regions
And there's lots more to come! New features will continue to roll out with each update. For reference, VEGAS 19 saw 5 updates, each that added new features, so this is far from the final feature list... AND YES, performance improvements are among the things being currently worked on to add to that list (some are already here, they started with audio by overhauling the VST system), and there have been a number of stability improvements already implemented, with more to come.
