If you use a deck with remote control and TC, like via FireWire or via RS422, you can digitize large amounts of material in an lower (offline) resolution, like 60k. After editing the finished timeline you can select everything in this timeline (CMD-A) and choose “Batch digitize selected” from the Media menu. Then change the image quality to something like 300k, and set trim handles to e.g. 1 second. The system will digitize only the needed material in your timeline from the original tapes again in the higher resolution, based on the TC information and reel numbers entered during the initial digitizing. This is the basic offline to online workflow in NLEs.
Btw. you should use HDR always, regardingless if you digitize at 60k, 300k or whatever. The other settings have some problems under OSX:
