Which AI Music Works for a Short Film Score?

Updated 2026-10-27·3 min read·Dialogue & audio

Two tools, two different strengths

AI music generators don't all do the same job when you're scoring a film. We scored the same short creature film three ways and compared them by ear. Our director had asked for ElevenLabs first. The verdict after listening: Suno "sounds good too", and then, "Suno is sonically richer."

This is the trade-off we found:

• Suno (we used its v6 model, instrumental, set to the cut's length) gives a fuller, more produced sound, and it returns two takes to choose from. You can't tell it when things happen. The swell lands where it lands.
• Eleven Music lets you lay out a composition plan, so sections can be timed to your cuts. That makes it the better pick when a sting must land on an exact frame.

Why Suno needs extra work in the mix

Suno masters loud. In our renders its tracks came in around -10 to -15 dB RMS, against roughly -29 for Eleven Music. Drop a Suno track onto a timeline at its default level and it will flatten your dialogue and the clip's own sound. The music is mastered like a finished song, but a score needs to sit under everything else.

How to score a short with AI music

1. Decide what matters more for this piece, a rich sound or exact timing. A mood-driven short with few hard hits suits Suno. A trailer cut to a beat suits a tool you can time.
2. Generate an instrumental at the length of your cut. Vocals fight dialogue, and a track that's the right length saves trimming.
3. Listen to every take against the picture. With Suno you get two. Choose the one whose biggest moment sits closest to where you need it.
4. Pull Suno down about 9 dB under the clips' native audio before you judge the balance. Then set it so dialogue sits about 6 dB over the music and effects.
5. Line up the hit by hand. Find the track's biggest moment, then trim the start or delay the track so that moment lands on your key cut. Fade the tail to the last frame.

An example

A 60-second short builds to a reveal cut at 0:41. The Suno take swells at 0:37. Delay the track 4 seconds and its peak meets the reveal. Trim the 4 seconds of overrun off the end with a short fade, and pull the whole track down until the actor's line before the reveal is clear. If you can't make a take line up, that's the moment to switch to a tool you can time.

A note on taste

This is one director's ear on one film. We didn't run a lab test. Try your own comparison on your own cut, since a richer track still has to hit the right moments.

In ShowMaker

The editor holds the music score alongside your dialogue and sound on the same timeline, so you set the music's level against the voices where you make the cut. For the levels themselves, see how loud music should be under dialogue. To start a short from a premise, try the AI short film maker.
