I just released version 3.0 of Debugmode Frameserver. This is a native 64-bit build tested with Vegas Pro 16.0 and Premiere Pro CC as well. You can get it from https://www.debugmode.com/frameserver/
Some of you may remember me as the developer behind Frameserver many years ago. After a long hiatus, I'm back to working on it regularly now, so feel free to send in your feature requests & bug reports ( ideally on github: https://github.com/satishsampath/frame-server ).
Many thanks to the Magix team for sending me a serial key for testing/developing on the latest versions of Vegas!
