How much does the music video API cost?

Pricing is flat per second of the song. The billable second count is the track's server-probed duration, not a client estimate. See the current per-second rate in the pricing table on this page; failed jobs refund automatically.

What audio length does the music video API support?

The song must be between 10 and 300 seconds — up to 5 minutes. The output music video length tracks the song, and billing uses the probed track duration.

How many reference images can I use?

One to seven. They act as the style or model references that fix the visual identity of the music video. Images must be public http(s) URLs — JPEG, PNG, or WebP.

Can I add subtitles or a lyric track?

Yes. Turn on add_subtitle to burn lyric subtitles into the music video and set subtitle_color, or supply your own .srt file via srt_url. With subtitles on and no file supplied, subtitles are generated from the song.

What resolutions and aspect ratios are available?

Resolution is 540P, 720P, or 1080P. Aspect ratio is 1:1, 16:9, 9:16, 4:3, or 3:4 — pick the frame that fits your target platform.

Where is the full music video API reference?

The full parameter list, error codes, and runnable cURL examples live at /docs/music-video-1-0.

Is AI Music Video Generator API free or paid?

Paid. Completed generations are charged at the rates in this page's pricing table. Eligible new accounts may receive promotional test credits; availability and amount are shown at signup or in the dashboard. Technical or provider failures are refunded automatically, except where this page documents a charged output-moderation block.

Does AI Music Video Generator API require a monthly subscription?

No. Pricing is pay-as-you-go: $1 buys 1,000 credits and credits never expire. Cost scales with what you generate rather than with a recurring fee.

How do I get an AI Music Video Generator API key?

Sign up and create a key in the dashboard, no card required. Pass it as a Bearer token in the Authorization header.

What is the Music Video 1.0 API?

Music Video 1.0 turns a finished song into a finished music video. Pass one audio track plus one to seven reference images that set the visual style, and the single async endpoint returns a video cut to the track — five aspect ratios, 540P, 720P or 1080P output, and optional burned-in subtitles that are either generated from the song or taken from your own SRT file, in any hex color you choose. Billing is per second of the song's measured length.

Why reAPI

A song in, a music video out

The music video API takes a track plus reference images and returns a video synced to the song. Output length tracks the song — 10 seconds to 5 minutes — with no timeline to edit.

Reference images fix the style

One to seven style or model images control the look of the music video, so the result matches your art direction instead of a generic template.

Pay for the seconds you use

Music video billing is flat per second of the song, measured server-side from the actual track length rather than a client estimate. Failed jobs refund automatically.
