Can I use my own script, video and music?

Yes. You can paste your own script, upload local video files up to 150 MB each and upload a supported background-music file up to 30 MB. You are responsible for having the rights required to use uploaded material.

Which video formats are supported?

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.

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.

Audio mixing guide

How to balance voiceover and background music

Narration carries the meaning; music supports it. Build the mix around intelligible speech, then use restrained music to shape tone and pace.

Voice-first workflowPhone-speaker checksHuman-reviewed August 30, 2026

Choose a voice for clarity, not novelty

Listen to the selected voice with a representative sentence from the actual script. Check names, abbreviations, numbers and technical words. A dramatic voice can be memorable but may fight an instructional topic. A calm voice can suit an explainer but feel slow when every shot changes quickly.

Match language and pronunciation to the audience. A multilingual label does not guarantee that every proper noun will sound natural, so preview difficult lines before committing to a full render.

Adjust speed after editing the script

Speed controls should refine delivery, not rescue an overcrowded script. If the narration must be accelerated until words blur, shorten the copy. Leave small pauses around important facts and scene transitions so viewers can process both sound and image.

Listen on normal playback rather than judging from a waveform. A numeric speed value is only a setting; intelligibility is the outcome that matters.

Select music that supports the message

Choose a track for mood, rhythm and texture rather than popularity. Busy percussion and dense midrange instruments often compete with speech. A simpler arrangement may sit below narration more easily.

  • Use steady music for calm explainers.
  • Avoid sudden accents under important words.
  • Check whether the track changes intensity during the video.
  • Use only music you are permitted to publish in the intended context.

Music is optional. A clear voice with well-chosen natural pauses is better than a crowded mix.

Set the voice first, then bring music underneath

Begin with the voice at a comfortable level. Add the music quietly and increase it only until it supports the tone. Test the busiest part of the track, not only its soft opening. If available, lower the music further during narration and allow a modest rise during an intro, pause or final frame.

Warning sign

The words are clear on headphones but disappear through a phone speaker.

Better response

Reduce competing music frequencies or volume; do not simply push the entire mix louder.

Avoid clipping. Excessive loudness can distort the export and create an unpleasant jump when viewers move between videos.

Review on more than one playback system

Listen once on headphones and once through a phone or laptop speaker. Confirm the first sentence is clear, every name is pronounced correctly, the music never masks speech and the final audio does not cut off abruptly. Watch captions at the same time to catch places where spoken and written wording diverge.

  1. Voice understandable at a normal device volume.
  2. No distracting pronunciation errors.
  3. Music remains supportive in its loudest section.
  4. No clipping, clicks or sudden level jumps.
  5. Ending has a deliberate fade or finish.

Measured example: settings are evidence, not a universal preset

The recorded autumn-leaves project used the Aria English voice at 100%, a 0.95× rate and built-in music at 15%. The downloaded MP4 measured −20.5 LUFS integrated loudness, 2.5 LU loudness range and −4.7 dBFS true peak. It also contained three pauses longer than half a second, including a 1.02-second pause near 27 seconds.

These numbers confirm the delivered file’s level and dynamics; they do not prove that every listener will find the voice clear. The screen recording itself has no audio track, so no listening judgment was inferred from it. A creator should still test the final MP4 on headphones and a small speaker.
