Music decides whether an ad feels finished. Suno inside v4v generates a track for the specific ad — matched to the product, the pacing, and the mood — instead of a generic loop from a folder called "upbeat corporate." For an 8–15 second vertical ad the track has to set energy in the first second, support the voiceover without competing, and resolve at the cut so the ad doesn't feel truncated. The reliable prompt recipe: genre + BPM + instrumentation + "no vocals" + explicit length (generate ~2–3 seconds longer than the video) + how it should end.
Prompt patterns that work
- "Soft ambient electronic, 90 BPM, warm synth pads, gentle hi-hats, no vocals, 12 seconds, calm and clean ending"
- "Driving trap beat, 140 BPM, punchy 808 bass, no lyrics, 12 seconds, builds in intensity, hard stop at the end"
- "Acoustic indie folk, 100 BPM, fingerpicked guitar, light percussion, warm and approachable, 12 seconds, fades cleanly"
The three checks before you ship
- Energy match at frame one — fast product motion over a slow intro reads as broken.
- Voiceover headroom — busy midrange fights the voice; favor pads and percussion under spoken lines.
- The ending — specify a hard stop or clean fade; an awkward cut is the most common tell of a rushed ad.
Why generate instead of stock?
Stock loops are licensed, generic, and rarely the right length. A generated track costs credits on the same balance as your video, matches your cut point exactly, and never appears in a competitor's ad.

FAQs
Can I make music without making a video?
Yes — Suno runs standalone in the AI Lab on the same credit balance.
Should ad music have vocals?
Usually no — vocals fight the voiceover. Say "no vocals" explicitly.
