Re: [Avid-L2] XDCAM HD workflow check

You do get less real time FX with long GOP codecs.

In fact, if you don't wan't triple-media, and have a little assistant time, you can just mount the disc directly AMA'd inside avid, and consolidate to XDCam50 - thus saving a couple steps and still getting the peace of mind that comes with having the footage as in the Avid MediaFiles MXF folder.
