On my most recent project for the California Immigrant Policy Center on the California Budget www.caimmigrant.org I am mixing footage from the Canon 7D camera and a Panasonic HVX200. It is really easy to combine these two formats into one sequence in Final Cut Pro. I was skeptical, but my DP Topher Osborn www.topherosborn.com assured me that it wouldn’t be a problem.
With a little research online using the keywords (transcode, canon 7D, FCP) I was able to find a good work flow using the program Compressor to turn the 7D files into ProRes files. I even picked up a little trick for making droplets with Compressor from this video tutorial.
