StorySplice example workflow

How a Sunflower Grows From a Single Seed

This genuine 40-second vertical video follows a sunflower from germination through flowering, pollination and the production of new seeds.

Public example · 0:40 · portrait 9:16 · English narration · burned-in captions

Download example MP4

01 · Brief

Explain one complete natural cycle

The story moves from a seed beneath the soil to germination, growth, flowering, pollination and the formation of new seeds. Each stage gives the narration a concrete visual purpose.

Format
Portrait 9:16
Final length
40 seconds
Tone
Warm, vivid and educational

02 · Script

Build a visible progression

Every sunflower begins as one striped seed, tucked beneath a thin blanket of soil.

The original 100-word narration uses short sentences and avoids the common misconception that mature sunflower heads continue tracking the sun.

03 · Visual plan

Match footage to each growth stage

Ordered searches covered seed planting, germination, emerging seedlings, green leaves, a developing bud, an open bloom, pollinators and a mature seed head. The sequence was reviewed frame by frame before publication.

04 · Review

Publish only after quality control

The final file contains 1080×1920 H.264 video and AAC audio at 30 fps. Captions remain inside the mobile safe area, the narration is clear over restrained music, and representative frames stay relevant to the sunflower lifecycle.

Editorial and visual review

What was checked before this example became public

Sequence integrity

Footage follows the lifecycle rather than mixing mature flowers into the germination stage. The order was reviewed against the approved narration beat by beat.

Claim correction

The script avoids repeating the common oversimplification that mature sunflower heads keep tracking the sun. The wording stays focused on visible growth stages instead.

Mobile composition

Representative frames were checked at 9:16 for subject visibility, caption contrast and safe placement above player controls.

Known limitation

The stock footage comes from more than one plant and location. It illustrates a lifecycle; it is not continuous time-lapse documentation of a single sunflower.

StorySplice workflow guide

How to turn a script into a narrated video

A strong result begins before rendering. Use this seven-step workflow to connect every line of narration to a useful visual, clear voiceover and readable caption.

7 practical stepsFor 15–60 second videosHuman-reviewed August 30, 2026

1. Define one outcome for the viewer

Write one sentence describing what a viewer should understand, feel or do after watching. A short video rarely has enough time to explain several unrelated ideas. A narrow outcome helps you decide which lines belong and which details should be saved for another video.

Also identify the intended audience and destination. A first-time viewer may need context that an expert audience already understands. A vertical social post usually needs a faster opening than a video shown inside a longer presentation.

2. Edit the script for spoken delivery

Writing that looks clear on a page can sound heavy when spoken. Read every line aloud. Shorten long clauses, remove repeated ideas and replace jargon with words a listener can understand on the first pass. Give each sentence one main job.

A 60-second narration is often around 120–150 English words, but language, pauses, names and voice speed change the result. Treat word count as a planning range, then confirm timing with the selected voice preview.

  • Open with the subject, tension or useful promise.
  • Put essential context before supporting detail.
  • Verify names, numbers and factual claims.
  • End with a conclusion or next step instead of stopping abruptly.

3. Give every narration beat a visual purpose

Divide the script into scene-sized beats. For each beat, describe what the viewer should see. Concrete searches built from a subject, action and setting usually work better than abstract themes or a repeated title.

Narration

“Before sunrise, the first jobs are already underway.”

Visual searches

farm sunrise · farmer preparing tools · rural morning mist

Do not force footage to prove something it does not show. If a clip is attractive but unrelated, it can weaken trust. Ordered footage is useful when the story follows a process; a more varied sequence can work when the narration is thematic.

4. Match the aspect ratio to the destination

Use 9:16 for vertical short-form feeds and 16:9 for conventional landscape players. Choose before selecting footage, because a wide clip may lose its subject when cropped vertically. Keep important faces, text and actions away from the extreme edges.

5. Prioritize voice clarity over background music

Preview the selected voice and listen for pronunciation, pace and tone. Names, abbreviations and technical terms deserve special attention. Background music should support the mood while remaining clearly below the narration. If the voice becomes difficult to follow on phone speakers, lower the music rather than raising everything.

Use only audio that you created, licensed or are otherwise permitted to publish. Keep a record of the source and license terms for every track.

6. Design captions for the smallest screen

Use strong contrast, an outline or background when footage is visually busy, and a position that avoids platform controls. Keep lines short enough to scan without covering the subject. Captions should follow the spoken meaning, but they do not need to reproduce every filler word if a concise edit improves readability without changing the message.

7. Watch the complete export before publishing

Watch once for meaning and once for technical problems. Check factual accuracy, scene relevance, pronunciation, caption timing, music balance, cropping, transitions and the final frame. Confirm that no stock clip contains an unexpected logo, identifiable person or context that changes the claim.

Recorded example: one project from brief to corrected export

On August 29, 2026, we recorded a complete StorySplice session for an autumn-leaves explainer. The project began with a 45-second brief and an AI-assisted draft, moved through an 88-word human-edited script and eight scene-specific searches, then rendered a 39.8-second MP4.

The first export was not treated as final. Playback showed that bottom captions could compete with native player controls, so the position was changed to Custom at 70% and the video was rendered again. This is the practical purpose of step seven: successful encoding does not prove that a composition is ready to publish.
