Great to hear!
If there's any before/after you're willing to share I'd be curious to see it. I don't recall ever seeing other people doing this stuff, just me playing around with things.
There's likely to be a reasonably good average grade that would work across all shots that you can use while editing, and then fine-tune once you're almost at picture-lock. That avoids you working on shots that don't end up in the final edit, but also means you're not working with the unprocessed footage, which can be distracting.
If that's a true stream of the data on the tape then that should be as good as it gets. Then the next steps would be how to de-interlace and process it further.
I seem to recall several ways to de-interlace, either with their pros and cons. One was to have each frame made up of alternating lines from the current and previous frame, and the other was to just duplicate the lines from the current frame. The former had more apparent resolution but had a horizontal blind type of effect on movement, and the latter had less resolution and was prone to flickering, especially on hard edges that ran horizontally. Choosing the overall approach might be subject-dependent, and maybe even shot dependent?
I'm curious to hear how you go with this as well.
