Define the job of the video
Write one sentence describing what someone should be able to do afterward. For an illustrative clothing repair, identifying a loose stitch needs less explanation than learning the full repair.
If the task is unclear, cutting ten seconds will not make the answer clearer.
Prepare concise and demonstrated versions
Outline a direct answer and a longer version that includes the evidence or process. Remove repeated introductions from both.
These are editorial variants, not minimum or maximum TikTok requirements. Use fresh examples with similar difficulty; never stretch a weak point just to reach a target length.
Compare the right outcomes
Record duration, available average watch time, completion, saves and relevant questions at the same post age. A longer video can have more seconds watched but a lower completion percentage.
Neither automatically wins. Separate paid campaigns and flag missing analytics rather than replacing them with guesses.
Choose by usefulness, then repeat
Keep the format that helps the intended viewer finish the task, with enough comparable observations to be credible. If comments repeatedly ask for the missing step, restore it or make a clearly linked follow-up.
Recheck with another topic; one unusually successful clip cannot identify an optimal duration.
