Edu Replay / Making It Usable

Chapters and signposting, so a person can find the part they need

Structure is the cheapest improvement available and reliably the largest.

The difference between a usable recording and an abandoned one is usually not sound, picture or polish. It is whether a viewer with a specific question can get to the answer in under a minute. Marked sections do that. A short list of the points where the topic changes, with plain descriptions of what each covers, converts a wall of duration into something that can be entered at the right place. It is a small act of cataloguing and it changes the entire relationship between a person and the file.

The best time to do it is while teaching, not afterwards. Saying aloud what is about to happen, naming the transition, flagging the worked example as a worked example, leaves markers in the material that anyone can find later without watching the whole thing. This is good practice in the room in any case, because it helps the people present follow the structure. That it also produces a navigable recording is a fortunate side effect of teaching clearly.

Where sections are added afterwards, the work does not need to be exhaustive. Half a dozen well chosen markers across a long session are worth far more than forty granular ones, because the point is orientation rather than indexing. Descriptions should say what a viewer will get, not what the segment is called on the schedule. There is a real difference between a marker reading topic two and one reading the difference between the two methods, worked through, and the second one is what makes the file worth keeping.
