I've been grading and rendering out of Speedgrade for months now with no problem. Now though, my "render" button is greyed out. I have not changed any of the settings I have been using. The clip has a name, a location to render out to and a render format. I've tried quitting and restarting Speedgrade, opening a new project, restating the computer with a PRAM reset. Nothing works. Any other suggestions? I'm using the most current version of CC on a Mac running 10.8.4. Thanks!
