Beat driven music video
A complete walkthrough of a 40 second music video with a Suno track, a beat map, Seedance audio references and cuts on the beat.
This recipe makes a 40 second music video where every cut lands on a bar line. The music comes first: you make the track, map its bars to seconds, then generate the pictures to fit. Seedance 2.5 takes a slice of the song as an audio reference so the motion follows the rhythm. Expect about 22 USD of generation at API rates plus a paid Suno plan.
The brief
| Item | Choice |
|---|---|
| Track | 40 seconds of an upbeat synth pop song at 120 BPM, made in Suno on a paid plan |
| Concept | LAN, a bicycle courier, races one glowing package across a neon city at night |
| Characters | One. No singing on camera, so no lip sync. |
| Style | Stylized anime inspired 3D, rain-slick streets, magenta and cyan neon |
| Length and format | 40 seconds, 16:9, 12 shots in 4 generations of 10 seconds |
| Model | Seedance 2.5 in Dreamina, with the song slice as @Audio 1 |
Why 120 BPM: one beat is 0.5 seconds and one bar of four beats is exactly 2 seconds. Every bar line falls on a whole second, which matches the whole second timestamps that Seedance 2.5 accepts.
Budget
| Item | Amount | Cost |

| Suno Pro | 1 month | 8 USD/month on yearly billing; 2,500 credits and 20 downloads a month |
| Character and location sheets | 2 to 4 images | A few image credits |
| Draft takes at 480p | 4 generations x 3 takes x 10 s = 120 s | About 12.40 USD (0.103 USD/second) |
| Final takes at 720p | 4 x 10 s = 40 s | About 9.20 USD (0.231 USD/second) |

Prices checked on 15 Oct 2026. The video figures use the official ModelArk rates as a yardstick. Dreamina shows its own credit cost before you generate, and the pricing page does not say whether an audio reference changes the cost, so check the quote on your first take. Suno's monthly billing price was not in the research; check the pricing page.
Make the song on a paid plan
Songs made on Suno's free plan cannot be used commercially, and they do not become usable if you upgrade later. Songs made while you subscribe keep their rights after you cancel. The free plan also has no downloads.
Walkthrough
Idea and track
Generate the song in Suno Pro first. Ask for an upbeat synth pop track at 120 BPM in the style description, then pick the best 40 seconds (for example the end of a verse into the chorus). Check the tempo by placing beat markers in your editor before you plan any shots. If the tempo is off, every cut in the plan will drift.
Keep the visual idea to one character and one kind of location. Stylized, short cuts forgive small drift, which is why music videos suit AI well.
Beat map and shot list
Write the song structure as bars, then give each section a cutting rhythm: longer holds in quiet parts, quick cuts in loud parts.
| Song time | Section | Bars | Generation | Cut every |
|---|---|---|---|---|
| 0 to 10 s | Verse end | 5 | A | 2 bars (4 s) |
| 10 to 20 s | Build | 5 | B | 1 to 2 bars |
| 20 to 30 s | Chorus | 5 | C | 1 bar (2 s) |
| 30 to 40 s | Outro | 5 | D | 2 to 3 bars |
| # | Song time | Gen | Framing and camera | Action |
|---|---|---|---|---|
| 1 | 0 to 4 s | A | Wide, slow aerial descent | Rain-slick neon street at night, empty |
| 2 | 4 to 8 s | A | Medium, tracking left to right | LAN rides her bicycle through the street |
| 3 | 8 to 10 s | A | Close-up, static | The package in her basket pulses with light on the downbeat |
| 4 | 10 to 14 s | B | Low angle, tracking | LAN stands on the pedals and speeds up |
| 5 | 14 to 18 s | B | Side tracking, 85mm | Neon signs streak past behind her |
| 6 | 18 to 20 s | B | Extreme close-up, static | LAN's eyes, reflected lights sliding across them |
| 7 | 20 to 22 s | C | Wide, static | The bike jumps a puddle, splash on the beat |
| 8 | 22 to 24 s | C | Overhead, static | The bike crosses a lit crossroads |
| 9 | 24 to 26 s | C | Close-up, static | Spinning spokes leave light trails |
| 10 | 26 to 30 s | C | Slow orbit | LAN rides as the street lights pulse |
| 11 | 30 to 36 s | D | Wide, static | She stops at a lit doorway and sets the package on the step |
| 12 | 36 to 40 s | D | Slow pull out | She rides away, the street goes quiet |
Reference images and audio slices
Make a character sheet for LAN (four views on neutral grey, no text) and a location sheet with three views of the same street. Use the same style line in every prompt: "Stylized anime inspired 3D, rain-slick streets, magenta and cyan neon, soft bloom."
Then cut the 40 second section into four 10 second audio files, one per generation. Seedance recommends reference clips of 5 to 10 seconds. Any editor can export these; with ffmpeg:
ffmpeg -i song.wav -ss 0 -t 10 part-a.wav
ffmpeg -i song.wav -ss 10 -t 10 part-b.wav
ffmpeg -i song.wav -ss 20 -t 10 part-c.wav
ffmpeg -i song.wav -ss 30 -t 10 part-d.wavSeedance 2.5 accepts an audio file as a reference on its own and up to 30 seconds of reference audio in total. Seedance 2.0 needs an image or video alongside any audio.
Video prompts, one per generation
Upload LAN's sheet first, the location sheet second, and the matching audio slice. Give every reference one job: the audio is for rhythm and cut timing, not for sound to copy. Timestamps sit on bar lines.
@Image 1 is LAN: use her face, hair, red jacket and bicycle only. @Image 2
sets the street and lighting only. @Audio 1 is for rhythm and cut timing
only. Stylized anime inspired 3D, rain-slick streets, magenta and cyan neon,
soft bloom.
[0s to 4s] Wide shot, slow aerial descent over an empty neon street at night.
[4s to 8s] Cut to medium shot, tracking left to right: LAN rides her bicycle
along the wet street.
[8s to 10s] Cut to close-up, static: the package in her front basket pulses
with light on the beat.
No subtitles.@Image 1 is LAN: use her face, hair, red jacket and bicycle only. @Image 2

sliding across them.

[0s to 6s] Wide shot, static: LAN rolls to a stop at a lit doorway, steps
off and sets a glowing package on the step, then stands still.
[6s to 10s] Cut to slow pull out: she rides away down the street and the
street goes quiet and still.
No subtitles.Use Draft mode at 480p for 3 takes per generation, keep the best, then render the final at 720p.
Editing on the beat
Put the master song on the timeline first and lock it. Add a marker on every bar line (every 2 seconds at 120 BPM). In DaVinci Resolve, AI Detect Music Beats places beat markers you can snap to; reviewers disagree on whether it is in the free edition, so check yours. In Premiere, drop markers and use Automate to Sequence. Then place each generation and trim every cut so it lands exactly on a marker. Generated cuts are often a few frames off the bar line; fix them here, not by regenerating.
If the song section is slightly too long or short, Resolve's AI Music Editor can stretch or shorten a track to length. It works best on beat driven music.
Audio
Mute every generated clip. The only sound in the final video is the master track from Suno. Generated clips may contain their own version of the music or invented sounds, and mixing them under the master makes the beat feel loose.
Finishing
Export at 1080p for web and social. On YouTube, disclose the video as altered or synthetic content: YouTube requires disclosure when AI music is the main focus of a video. AI music can still trigger YouTube Content ID claims even when you hold the rights.
What usually goes wrong
| Problem | Why | Fix |
|---|---|---|
| Motion ignores the beat | Users report Seedance ignores the audio reference or invents sound in roughly 15 to 20% of runs | Make 3 takes per generation and pick the one in time; fix cut points in the edit |
| Cuts land a few frames off the bar | Timing in generated clips is approximate | Trim to the bar markers in the edit |
| LAN looks different in each generation | Four separate generations, no shared memory | Same character sheet, same style line and same upload order in all four prompts |
| Music video cannot be monetized or gets claimed | Free plan song, or Content ID match | Make the song while subscribed to a paid plan, and expect that claims can still happen |
| Lip sync looks wrong | Singing on camera is hard | Keep the character not singing, as in this brief, or treat lip sync as a separate step |
There is no independent performance data for AI music videos yet. The case for them rests on workflow advice: stylized looks and short cuts hide drift, and Seedance's audio references suit beat driven montage.
