# Learning-video length decision sheet

Use one sheet per video or independently addressable segment. Complete it before recording, after the first edit, and after learner testing. A duration is an output of these decisions—not the first requirement.

## 1. Learner and use

- Project:
- Owner:
- Revision and date:
- Primary learner group:
- Relevant prior knowledge:
- Viewing context, device, and likely interruptions:
- How the video will be used: introduction / complete lesson / demonstration / scenario / reference / other:

## 2. One learner job

Complete this sentence: After the experience, the learner can **[observable action]** with **[knowledge, evidence, or object]** under **[important conditions]**.

- Evidence the video and interactions can collect:
- What that evidence cannot prove:
- What must be assessed outside the player:

## 3. Keep, support, remove

| Source beat | Why it exists | Essential / supportive / removable | Risk if cut | Reviewer |
|---|---|---|---|---|
| | | | | |
| | | | | |
| | | | | |
| | | | | |

Preserve required warnings, decision conditions, visual evidence, exceptions, terminology, access, and explanation. Question repeated greetings, decorative transitions, duplicated narration, and setup that does not serve the learner job.

## 4. Segment boundaries

| Segment ID | Learner-facing title | Coherent idea or phase | Prerequisite | Source time | Why the boundary belongs here |
|---|---|---|---|---|---|
| | | | | | |
| | | | | | |
| | | | | | |

Do not cut in the middle of a causal relationship, safety condition, sentence, worked step, or continuous action the learner must integrate.

## 5. Interaction rhythm

| Interaction ID | Conceptual boundary | Learner action | Source evidence available | Feedback and continuation | Expected learner time |
|---|---|---|---|---|---|
| | | | | | |
| | | | | | |
| | | | | | |

- Why does each interaction exist?
- Which prompts could be removed without weakening the learner job?
- Does any prompt cover its own evidence, interrupt a complete explanation, or leak the answer?

## 6. Complete time estimate

- Edited source time:
- Required interaction and feedback time:
- Expected reading, caption, description, and response time:
- Likely replay and recovery time:
- Required route estimate:
- Supported route range:
- What time expectation will learners see?

## 7. Access and delivery

- Caption owner and review status:
- Critical visual information and description route:
- Keyboard and non-pointer route:
- Phone and embed sizes tested:
- Bandwidth or offline plan:
- Replay, seeking, and answered-review behavior:

## 8. Prototype and release evidence

- Riskiest beat prototyped:
- Representative learner roles included:
- Points of replay, confusion, abandonment, or access failure:
- Immediate aligned response evidence:
- Delayed or transfer evidence, if claimed:
- Alternative explanations for observed analytics:
- Changes made and why:
- Subject-matter approval:
- Accessibility review:
- Published desktop check:
- Published phone check:
- Next review date and trigger:

## Final decision

- Final source duration:
- Final required-route estimate:
- Why this is the shortest coherent treatment for this learner job:
- What would trigger a new cut, segment, or delivery format:
