Suno terms: remixes are non-commercial; edit ads on the video side

Suno's terms, as read on 2026-10-04, say that a Remix, meaning another user remixing your Output through the service, may only be used for lawful, personal and non-commercial purposes, regardless of subscription tier. The same terms give paid-tier subscribers the rights Suno owns in the Outputs generated from their Submissions. For an ad editor the practical rule is: use the song you downloaded as delivered, do the cutting, fading and ducking in your video timeline, and never ship a Suno Remix made by someone else in a commercial ad.

What the remix clause says

The Suno Terms of Service define a Remix as an output created when other users of the service, called Remixers, remix your Outputs through the service's features. A Remix is a joint work owned equally by you and the Remixer, and it may only be used for lawful, personal and non-commercial purposes, regardless of subscription tier. The clause is about that remix feature. It does not say that trimming or fading your own downloaded file is a remix, and this post does not claim it is. If your ad depends on a reading either way, ask Suno in writing.

Moving the edit to the video side

With Sume, the cut can live in the timeline document instead of in a new audio file. Timeline 1.0 takes soundtrack with url, gain_db, loop, fade_out_seconds and duck_db, and audio.source_in sets an in-point into a single audio spine. The original file stays untouched, and the changes are declarative and reviewable, which helps when someone later asks which version of the song went into which ad.

If you would rather generate to length

For short ad versions you can skip cutting a long song. Sume's Music Router rejects duration but accepts length in the prompt, such as "a 30-second track" or section markers like [0:00-0:30] Intro: ..., and the result is a new generation at a fixed $0.125 whatever the length. The terms for that route differ from Suno's, so read them rather than assuming they are looser.

• Keep the downloaded file as the source and record where it came from.
• Do not use another user's Suno Remix in a commercial ad.
• Do not strip or rewrite provenance metadata.
• Log which terms version each ad shipped under.

Why this belongs in the edit brief

Rights questions get discovered at the end of a project, when someone asks where a track came from. Put the question in the brief up front. The timeline audio split operation can make reusable slices of your own audio, and the same record-keeping applies. This post summarises a page read once and is not legal advice.
