TL;DR: How easy and quick is it to change file names and reinitialize takes on the 680?
Long version:
I'm thinking about picking up one of these. My taping rig has been the HD-P2 for at least 10 years now but I actually use it more for work these days, which is running sound for various film/video productions. I've always liked the timecode/video sync features, but with Plural Eyes software now, not many productions mess with timecode anymore. I would still use the P2 if recording a concert with video (due to drift issues on such a long continuous take), but that's not an issue on most of the stuff for which I get hired (takes are usually no longer than a few minutes).
So, right now I use 2 different setups when working on a film... when we're on a set I use a laptop/interface setup and Boom Recorder software which allows for quick and easy naming of files/metadata with scene, shot, take info, etc. When we're in the field I use the P2, and while there's no metadata, what I do is create a new project from template for each shot (labeled with the scene/shot number) and then the unit automatically increments the take, starting with 00 with each new project/shot.
So my question about the 680 is how easy is it to do file naming for each new shot (as compared to my workflow on the P2), and how does that relate to take incrementation? I browsed through the user manual and it seems like it might be a bit convoluted (user presets, reinitializing takes)? There usually isn't that much time between finding out what the shot number is and the start of a take... the last thing I want is the crew waiting on me while I'm setting filenames. But asset management is very important when you're dealing with the number of files that your average day's production generates. A 680 could easily replace the P2 as a field recorder as well as my laptop setup for use on sets, albeit at the expense of quick and robust file naming/metadata. As long as it's not too cumbersome to get the pertinent info stored quickly, it seems like the way to go.
