When I was “filming” government footage this was standard. You get the idea: talking head talking a lot followed by another talking head rebutting the previous talking head. (Honestly I love the policy debate, ergo C-SPAN.)
When it’s time to edit, treat the camera archive as digital tape. That means it is an old school work flow. The mp4 capture is just a “tape”; first step, then, is to convert the selects into edit formats. FCPX has a great workflow for this. However, it will require storage space.
(This is a real issue that we should talk about more.)
