I'm a new user of Adobe Speedgrade CS6 and, this is going to sound terribly beginner, but no matter what I set the output settings for the timeline to, Speedgrade won't allow me to hit 'render'. That is, the render button is greyed out. I have a similar problem with the 'save as an EDL' option. Would someone be able to help? I'm presuming there's some basic thing I'm not doing right.
