This document outlines a proposed 4K production workflow for an educational institution. The goals are to design a feasible 4K workflow, analyze weaknesses and bottlenecks, provide guidance to students on 4K production, and improve video production services. The workflow involves testing 4K camera recording options and hardware, an offline post-production process using DaVinci Resolve then Premiere Pro, and conclusions that it enables affordable 4K production and prepares students for industry work, though battery life and long-term storage are drawbacks.
