Product training starts aging the moment the interface changes. The answer is not to avoid detail. It is to make the lesson modular enough that one changed step does not invalidate the whole recording.
Record in meaningful sections
Break the workflow at natural decision points: setup, action, review, and next step. Each section should make sense on the timeline and carry only the narration it needs. When one screen changes, you can replace that section instead of rebuilding the story.
Keep context outside the capture
Use editable captions, callouts, and voiceover for explanations that may change. Keep branding, framing, and camera treatment in the project rather than baking them into the raw recording. The more editable the context remains, the less expensive every update becomes.
Separate the product truth from the teaching layer
The screen recording shows what happened. The teaching layer explains why. Treating them separately makes it easier to revise terminology, emphasize a new control, or replace a dated instruction without disturbing the rest of the workflow.
Review the outcome, not every frame
After an update, replay the transitions around the changed section and verify the final state. If the promise, sequence, and next step still hold, the lesson is ready again.
