My experience and general feedback I have read are the exact opposite -
AMA is more dependable maintaining the proper gamma levels than
traditional import where there is a lot more involvement of the QT engine.
I just calibrated my monitor using X-Rite colorimeter and generated the
video test signals using AMA'd files. Confirmed it using a Leader HD scope.
I would relink AMA then transcode to what ever codec you prefer (DNX or
uncompressed). For Canon 7D/5D DNX185 should be more than sufficient.

We linked all those folders to bins (one bin per camera card) using AMA, then each clip was transcoded to DNxHD36, one bin at the time. Hundred hours of footage.

It's my first film shot on a 5D, but I followed a similar workflow on several films before which were shot on XDCam and on which everything went smoothly: Link via AMA / Transcode to DNX36 / Edit / Relink final sequence to original XDCam / Export Tiff sequence for color grading on Colorus.

I need to export tiff files that would have the full 000-255 range: what is the best way to do that when I relink my final sequence? Any settings (project settings, etc) I should be aware of? What settings for export?
