Slides Narration Video Best Practices (2Slides + Remotion) — From One Prompt to a Ready-to-Share MP4

Creating a slides narration video used to be a multi-hour workflow: outline → design slides → write a script → record voiceover → sync timing → render.

With 2Slides + Remotion, you can now do it in one prompt and get a clean MP4 in ~10 minutes—good enough for product explainers, training, and marketing content.

This guide is a practical checklist for shipping higher-quality narration videos consistently.

What you’re building

Slides + voice + Remotion pipeline diagram

A fully automated pipeline:

Generate slides (pages/PDF) with 2Slides
Generate narration audio with 2Slides
Download assets (pages + audio zip)
Create a Remotion project and sequence pages + audio
Render MP4

The 80/20: what makes narration videos feel “professional”

1) Script first, slides second (even if AI generates both)

A narration video is audio-led. If the narration is clear and well-paced, viewers forgive simple slides. If narration is messy, no amount of design saves it.

Best practices

Keep sentences short (spoken language, not blog language)
One idea per slide
Avoid reading dense paragraphs verbatim

2) Timing rules that never fail

Target 12–18 seconds per slide for explainers
Narration pace: ~140–170 wpm (English)
If narration for a slide exceeds 25–30s, split the slide

3) Visual rhythm: treat slides like cuts

A narration video should feel like “cuts” in video editing.

Alternate layouts (text-heavy → visual → text)
Insert an occasional “breathing slide” (a big headline + 1 icon)
Use consistent margins and font hierarchy

4) Audio quality: loudness and silence

Even with great TTS, you still want predictable audio levels.

Normalize to a consistent loudness target (e.g. -16 LUFS for web)
Add 200–500ms padding between slides when switching topics
Avoid abrupt starts: use a short fade-in (50–100ms)

5) Accessibility: subtitles are a multiplier

If the workflow can produce captions, do it.

Burn-in captions for social distribution
Or ship a sidecar file

Recommended workflow in Claude Code + OpenClaw (copy/paste)

You can run this workflow from an agent environment (Claude Code / OpenClaw) by installing two skill packs:

2Slides skills: https://github.com/2slides/slides-generation-2slides-skills
Remotion skills: https://github.com/remotion-dev/remotion/tree/main/packages/skills

Then use a single prompt like this (replace the topic):

Please help me create a slides narration video for the topic: [YOUR_TOPIC_CONTENT]

- Create slides using 2Slides create pdf slides API; decide the slide pages count by AI.
- Generate voice narration using 2Slides API.
- Download slides pages and voices zip using 2Slides API.
- Create a Remotion project and a slides narration video using pages and voices in sequence.
- Render and output the video.

Best practices for each pipeline step

Step 1) Slide generation (pages/PDF)

Goal: create slides that are readable at video resolution.

Prefer larger fonts, fewer bullets
Avoid tiny charts (video compression kills them)
Use 16:9 layouts, high contrast

Pro tip: ask the agent to choose slide count based on content length.

Step 2) Voice narration

Goal: match narration structure to slide boundaries.

Generate narration per slide (not one giant audio)
Enforce a consistent tone ("confident, calm, concise")
For acronyms/brand terms: provide pronunciation hints

Step 3) Asset packaging (zip download)

Goal: make rendering deterministic.

Name assets in order: , … and , …
Keep everything in a single folder for Remotion

Step 4) Remotion sequencing

Goal: correct sync, zero glitches.

Set slide duration from audio length + padding
Crossfade (optional): 6–12 frames is enough
Consider a subtle background music bed at -28 to -32 dB

Step 5) Rendering

Goal: export a share-ready MP4.

Use H.264, 1080p, ~8–12 Mbps for most use cases
Validate on mobile (common failure: text too small)

QA checklist (before you ship)

Does each slide’s headline match the narration?
Any slide stays on screen for >25–30s? Split it.
Any slide shows tiny text? Increase font size.
Any abrupt audio start? Add a short fade/padding.
Add subtitles for social distribution.

Next step

Try it with a real topic you care about (a product feature, onboarding flow, or weekly update). If you can turn one prompt into a consistent video pipeline, you can ship content faster than your competitors.
