No such thing... you must have a BluRay burner
Well, a lot also depends on the nature of the MOV files -- since they can include any of hundreds of codecs, resolutions and quality levels -- and how well they are matched to your project settings.
When you set up your project, did you select project settings for a DSLR at 1080p?
I have explained my background poorly. I used my Canon EOS 5D Mk11 to take outside/sunny 31 X very shortly "snips" of folks enjoying a birthday party. These 31 x snips were .MOV & 1088 x 1920 frames @ x 25. My snips viewed on my Computer Desktop show crisp HD pictures. Using various formats (HD) with Adobe Premiere Elements10. I find all video deteriorate where they disappointed my original efforts. (Exception only format .m2t).
What Project Preset did you choose, at New Project? Did you choose one of the DSLR Presets, that matches your Canon's Source Footage?
Bill is proposing exactly the same thing I am, rahewitt. It all has to do with setting up your project correctly. If you don't select the project settings for DSLR 1080p25 video, you will not get a good quality video output.
