"I am a video journalist and Avid MC5 is relatively new to me. When I import clips from my iphone 6 into Avid MC5, the quality is heavily degraded. I work in SD, so of course there should be a difference, but the imported video look very compressed and pixelated. I suppose that this is an issue with codecs and/or import settings, but I have no idea on how to solve it."
As far as we know, the iPhone (including iPhone 6S, iPhone 6S Plus, iPhone 6, iPhone 6 Plus, iPhone 5S, iPhone 5, iPhone 5C, iPhone 4S, etc.) records in MOV files compressed with H.264 codec. The H.264 codec is a final delivery codec; it is not one you want to use for editing in Avid Media Composer.
