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.

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.

Try the same workflow

Start with your own subject or finished script
