Richard,
In the upressing section of your workflow guide you mention mixed frame rates. I have iPhone footage and Canon 60d footage on this edit. The third camera of a 3 camera interview is an iPhone. I want to create grouped clips of the 3 camera interviews and quickly edit with them, but what about the 29.976 iPhone footage? Is the proper procedure to transcode the iPhone’s 29.976 HD footage in a 29.976 project and then open the bins of that project and copy the clips into my 23.976 project? Will grouping mixed frame rate clips screw everything up?
