I'm going to be in the field, and have never shot so much video remotely (or not that much either at once).
Likely it will be about 3-4 hours of video, lots of start and stop, focusing, interviews, b-roll video, etc.
How many batteries would you bring (I have 4 Batteries)?
Two camera bodies.
How much memory (I was thinking about 64 GB or more)?
I'll also bring a grey card, reflector, lenses, flash (For night photos if needed), digital audio recorder, with extra AA batteries.
What am I missing or mis allocated for this? I'm trying to plan well. Suggestions?
