AI SOUNDTRACK
Add Music to Your Video
Scene by Scene
Upload your video. AI detects scene changes, emotional shifts, and key moments — then matches licensed music where it fits best.
Music changes when the story does — not at every cut.

MATCHING, NOT GENERATING
Does the AI Generate the Music?
No. VividSpark matches your video to tracks that already exist in our licensed library. The AI reads your footage and decides which track fits each scene and where it should change — it does not compose or render new audio. Every track you hear is a finished, licensed release.
A real track, not an improvisation
You can preview the full track, see its length, and hear it the same way every time. Generated audio is different on every run, which makes it hard to judge before you commit to it.
Licensing you can point to
Each track carries a defined licence tier, so what you may do with it — personal use, monetised content, client work — is settled before you publish rather than after.
Our tracks are produced using a combination of human curation and AI-assisted music tools, under valid commercial licensing from the source platforms. You're responsible for any AI disclosure requirements on your distribution platform (e.g. YouTube, TikTok labeling rules where applicable).

WHAT MAKES IT DIFFERENT
AI That Understands Your Video—Not Just Its Length
Most tools make you choose or generate one track, then leave you to time it yourself. VividSpark analyzes the story, emotion, and pacing, selects licensed music, and decides where it should start, stop, and change.
Scene and emotion detection
AI reads emotional shifts, scene changes, and key moments before choosing music—not just the total runtime.
Music changes when the story does
Different moments can use different tracks. AI changes the music only when the story, mood, or pacing calls for it.
Dialogue and ambient sound preserved
Music is added without removing your dialogue, sound effects, or ambient sound.
Every placement is editable
Remove any music section with one click, or describe a different mood and AI rematches that moment instantly.
HOW IT WORKS
From Raw Video to a Finished Soundtrack
Three steps. One upload.
Upload Your Video
Upload an MP4, MOV, WebM, AVI or MKV. Add music to a video without background music, or remove and replace existing music.
AI Matches Music Scene by Scene
AI detects emotional shifts, scene changes, and key moments, then places licensed music where it works best.
Fine-Tune and Export
Remove any music section with one click, or describe a new mood to rematch it. Export when everything feels right.
NATURAL LANGUAGE FINE-TUNING
Not the Right Mood?
Just Describe It.
Tell AI the mood, style, or energy you want for any scene—and it rematches that moment instantly. No library browsing. No manual syncing.
