When to re-record your course (and when not to)
Decide between patch updates, new lessons, and a full remake without endless rework.
Software and tools change; your teaching improves. Not every change needs a full reshoot. Errata notes, short addendum videos, or an updated resource link often fix confusion faster than redoing hours of footage.
Re-record when the core promise is wrong: the method you teach was replaced, or feedback shows the middle modules lose everyone. That is a structural problem, not a cosmetic one.
Batch fixes. Collect issues for a month, then record replacement segments in one session so audio and lighting stay consistent.
Communicate updates in your course description or at the start of the relevant lesson so enrolled students see what changed. People forgive outdated UI when they trust you are maintaining the material.
