Boreal

boreal is the default when model is omitted. It renders longer videos than Boreal-H3 (up to 60 seconds at 720p) and can be driven by an audio track. For the request lifecycle (polling and webhooks), see the Boreal overview. For start and end frames or reference media, use Boreal-H3.

Pricing

Billing is per started 10 seconds of video. Each resolution has a maximum video length, which applies to duration and to the length of audio_url:

Resolution	Maximum length	Credits per 10 seconds
720p	60 seconds	1
1080p	30 seconds	3
2k	15 seconds	12

For example, a 15-second 720p video costs 2 credits. Failed videos are refunded automatically, and generated videos stay available for at least 7 days. See Pricing, limits and retention to compare every model.

Examples

The “Audio driven” request above, rendered at 2k. The video is as long as its 10.4-second audio, billed as two 10-second units (24 credits).

Audio driven

Parameters

Parameter	Required	Description
`model`	No	`boreal` (default). For `boreal-h3`, see Boreal-H3.
`prompt`	Yes	What the video should show: subject, action, camera, and any dialogue or sound.
`image_url`	No	Start frame. The video follows the image’s own aspect ratio unless `aspect_ratio` names one, which centre-crops the image to it.
`audio_url`	No	Audio track (`mp3` or `wav`) that drives the video. When set, the video is as long as the audio (within the same length limit as `duration`) and `duration` is ignored.
`resolution`	No	`720p` (default), `1080p` or `2k`. 2k is 2016 px on the long edge for 16:9 and 9:16, and 1440p for 1:1, 4:3 and 3:4.
`aspect_ratio`	No	`auto` (default), `16:9`, `9:16`, `1:1`, `4:3` or `3:4`. `auto` follows the start image, and is 16:9 without an image.
`duration`	No	Video length in seconds, greater than 0. Up to 60 at 720p, 30 at 1080p and 15 at 2k. Default `10`.
`negative_prompt`	No	What the video should avoid.
`webhook_url`	No	URL that receives the result when the video is ready.

Sending a Boreal-H3-only input (end_image_url, reference_*_urls, prompt_enhancement) or a Boreal-H3 resolution (768p, 1088p) with model: "boreal" returns a 400 error.
