Does exporting movie using same sequence settings lose quality?
 

Hi,

I've received a .mov file that uses the AJA Video Systems Xena codec. It is a few reels of my short film shot in 16mm.

However all the shots are in one big 450GB .mov file and I want to cut them out without losing any quality. (After I cut them out I'm going to convert them to a 422(Proxy) to edit with)

This is what I do in Final Cut Pro 7:

Drag the file into the Final Cut timeline, click yes to set sequence settings the same as the mov file. Set my in and out points of the shot that I want. Then,
File > Export > QuickTime Movie...
Setting: Current Settings
Include: Audio and Video
Markers: None
[Deselect] Recompress All Frames
[Select] Make Movie Self-Contained

I don't want to lose any quality and I don't want to re-encode the files, I just want to cut them out of the original 450GB .mov file. Is this workflow right?

That will work.
