Case 13: Teaching Materials to Narrated Video

Scenario

Marcus teaches at a professional certification prep center. He has a structured question bank in JSON with questions, answers, and explanations. Turning that into video courseware used to mean: manually building PPT, then recording slide-by-slide. A 30-question set took at least two days. He wanted to see if QoderWork could automate the whole pipeline.

File Prep

Desktop/Course-Production/
├── Structured-Question-Bank-Vol1.json
├── Answer-Framework-Template.pptx (optional, for PPT style)
└── Intro-Outro-Assets/ (optional)

Select your folder

Select the Course-Production folder.

Generate PPT

Read "Structured-Question-Bank-Vol1.json" and create one PPT slide per question:
- Top half: question text
- Bottom half: key answer points (bulleted)
- Last slide: answer framework summary
Match the style of "Answer-Framework-Template.pptx"

Generate narrated video

Turn the PPT into a video:
- Add voiceover per slide (based on answers, conversational tone)
- Adjust slide duration by content length
- Output as MP4

What QoderWork Did

QoderWork read the JSON, generated a 30-slide PPT, turned each slide into spoken narration, and produced a narrated video. What used to take two days was done in one morning.

Ongoing Use

Marcus adds new question sets weekly: drop a new JSON file in the folder and say "New Vol 2 questions added. Generate PPT and video in the same format." He also packaged the flow as a Skill so teaching assistants can run it.

Key Metrics

Metric	Result
End-to-end	Materials → PPT → video in one flow
Scope	Training, teaching, knowledge sharing

Pro Tips

Use stepwise prompts + Skill packaging for long, multi-step tasks. Marcus split the work: first PPT (data + template style), then video (narration + timing). Each step has clear inputs and outputs. If something’s off, you fix one step instead of redoing everything. He then used create-skill to turn the flow into a Skill for the team. Break complex tasks into steps, then package as a Skill for reuse.
