Applying 'Scalable Asset Library' to On-Set Micro-Content Capture?

Hey everyone,

I'm Chris O'Brien, a Key Grip, and I'm wrestling with a concept I've heard bouncing around lately: the 'scalable asset library' for micro-content. Essentially, thinking about how we shoot narratives, but also capturing those quick, shareable social snippets (B-roll, behind-the-scenes, quick soundbites) from the start, rather than scrambling for them in post or during reshoots.

Currently, we’re shooting a mid-budget indie feature on an ALEXA Mini LF with an ARRI Signature Prime set. Our usual workflow is pretty locked in for the main narrative. We've tried carving out a few minutes at the end of a setup to grab some BTS on an iPhone or a C70, but it often feels rushed or we miss opportunities because we're just focused on the main takes.

I'm curious how other grips, lighting, or even camera departments have actually integrated this 'scalable asset library' idea into their pre-production and on-set process. How do you plan for it? What crew positions or gear (like a second unit RED KOMODO or an a7S III dedicated to this) have you found effective without disrupting the primary shoot? I'm genuinely trying to wrap my head around a practical, repeatable way to do this without adding chaos.

How have you adapted the 'scalable asset library' concept into your pre-production planning and on-set shooting process to ensure you capture these micro-content pieces from day one?
