I'm a long time photographer, but new to video editing and just have a couple of basic questions that I'm hoping someone who uses Final Cut Pro X can help me out out (ie Video Editing 101 questions;-) So, I'm shooting video with a Canon 7D Mark II DSLR and a Sigma 35 1.4 ART lens. On this particular camera, I have the option of shooting either .MOV or in MP4 files. Also, I'm shooting in Full HD (1920 X 1080), 30FPS and All-I mode. So, I'm shooting the fullest resolution and least compressed files this camera can shoot. Note: I've tested shooting in both .MOV and MP4. My goal is to import the video into FCPX, edit it and output it for my wife's upcoming Youtube channel. My questions are: Should I be shooting in .MOV or MP4? I want the highest quality video and am not sure which to choose. Will one versus the other make a difference in my ability to edit the video in FCPX? When I view the "raw" .MOV or MP4 files using "Quicktime Player", the video looks very clean and appears to be very high resolution. However, when I import the video into FCPX, there seems to be some very noticable degradation in video quality happening. I've tried checking the "Create Optimized Media" checkbox in the Transcoding section of the FCPX import window (ie which creates a ProRes 422 copy for editing) and have also tried unchecking this box (ie to import the MP4 file....for example....without transcoding). Both methods appear to result in degradation of the video when viewing in FCPX. My questions around this are: Is this normal that video quality is degraded when importing into FCPX? I can't imagine this is the case. I'm sure I'm missing something. When should I be transcoding the video footage on import by checking the "Create Optimized Media" checkbox? Should I only do this when importing a file shot in .MOV format? I'm confused about when to "transcode" into ProRes 422 and when to just import the footage as shot (ie .MOV or MP4). Thanks for the help!
