You can create portrait 9:16 or landscape 16:9 videos, with target lengths from approximately 15 to 60 seconds. Choose portrait for phone-first feeds and landscape for conventional widescreen players.

Can I preview a video before downloading it?

Yes. Completed videos can be played in the browser and downloaded as MP4 files from the project workspace or Recent videos.

How long are videos stored?

Generated task media, uploaded local videos and uploaded background music are scheduled for automatic deletion after seven days. Download anything you want to keep.

Can I use generated videos commercially?

The Terms permit lawful personal or commercial use to the extent allowed by law, but you must review the result and secure all necessary rights, licenses and permissions.

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

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

Final length
40 seconds

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.

Caption design guide

How to design readable captions for vertical video

Captions must compete with moving footage, small screens and platform controls. Design them as part of the composition instead of adding them after everything else.

9:16 videoReadability checklistHuman-reviewed August 30, 2026

Keep captions inside a practical safe area

Vertical platforms place interface controls near the top, bottom and right edge. Exact overlays vary by platform, device and viewing mode, so there is no universal pixel value. Keep essential text away from the extreme edges and preview it inside the destination app before publishing.

Bottom captions are familiar, but they should sit high enough to avoid descriptions and navigation. Move them higher when the subject’s hands or product occupy the lower third. The safest position is the one that preserves both the words and the visual evidence.

Use short, meaningful caption units

Break captions at natural phrase boundaries. A viewer should understand each unit without holding half a sentence in memory. Avoid leaving a preposition, article or person’s name stranded on a separate line. Two concise lines are generally easier to scan than a wide block of text.

Hard to scan

Before sunrise the first jobs on the farm are already getting underway.

Clearer grouping

Before sunrise,
the first jobs are already underway.

Do not remove words in a way that changes the meaning. When shortening is appropriate, edit the narration and captions together so they remain aligned.

Create contrast that survives changing footage

White text may look clear over one dark scene and disappear over the next bright sky. An outline, shadow or semi-opaque background helps maintain contrast across varied stock footage. Use a restrained treatment: a very thick outline or saturated block can become more distracting than the video.

Colour should not carry meaning by itself. Viewers with colour-vision differences still need a shape, label or wording that communicates the distinction.

Choose size by testing, not by copying a number

Font size depends on video resolution, typeface width, line length and viewing distance. Start with a size that supports two short lines, then preview the exported video at normal phone size. A caption that looks elegant on a desktop editor can be unreadable when the video occupies a narrow feed.

  • Use a typeface with clear letter shapes.
  • Avoid very thin weights over moving backgrounds.
  • Check punctuation and accented characters.
  • Keep capitalization consistent; full uppercase slows reading when overused.

Give viewers time to read the complete thought

Captions should appear with the corresponding speech and remain long enough to read. Rapid word-by-word animation can create energy, but it also increases visual load and makes corrections harder to notice. Phrase-level captions are usually calmer and more accessible for explainers.

Check where a caption changes during a pause. A new line should not imply the speaker has started a different point before the audio does.

Test the finished file under realistic conditions

Watch the video once without sound, once on a small screen and once over the busiest visual section. Confirm spelling, timing, contrast, safe placement and line breaks. Check names and numbers against the approved script rather than trusting automatic transcription.

Captions improve access, but they are not a complete accessibility solution for every audience. Consider a transcript or audio description when the communication goal requires it.

Recorded correction: Bottom was readable, but not safely placed

Our first autumn-leaves export used the Bottom preset, Be Vietnam Pro Medium, white text, a two-pixel black outline and a rounded black background. The words were readable inside the editor. When the actual video was reviewed in a browser player, the caption area was too close to native controls.

The correction was specific: keep the same type and contrast treatment, change Position to Custom and set the vertical position to 70%. The video was then rendered again and the downloaded MP4 was rechecked. The lesson is not that 70% works everywhere; it is that a preset must be validated in the intended player.
