Seedance and Seedence Models

Seedance and Seedence modes, configured credit matrices, and Vidrush API examples.

Overview

Vendor: ByteDance. This family includes Seedance 2.0, its Fast and Mini variants, Seedance 1.5 Pro, and the separately configured Seedence 1.0 models. Seedance 2.0, Fast, and Mini are served through the FreeModel provider (APIPod SKUs), matching ViewMax. Fast and Mini add frame and reference controls; 2.0 also exposes 1080p and 4k.

Supported modes

Model	Mode	Durations	Resolutions	Aspect ratios	Audio
`seedance-2-0`	text-to-video, image-to-video, frames-to-video, reference-to-video	4s, 5s, 6s, 8s, 10s, 12s, 15s	480p, 720p, 1080p, 4k	1:1, 21:9, 4:3, 3:4, 16:9, 9:16, Auto	Yes

`seedance-2-mini`	text-to-video, image-to-video, frames-to-video, reference-to-video	4s, 5s, 6s, 8s, 10s, 12s, 15s	480p, 720p	1:1, 21:9, 4:3, 3:4, 16:9, 9:16, Auto	Yes
`seedance-1-5-pro`	text-to-video, image-to-video	4s, 8s, 12s	480p, 720p, 1080p	1:1, 21:9, 4:3, 3:4, 16:9, 9:16	Yes
`seedence-1-0-pro`	text-to-video, image-to-video	5s, 10s	480p, 720p, 1080p	text-to-video: 21:9, 16:9, 4:3, 1:1, 3:4, 9:16; image-to-video: no option	No
`seedence-1-0-pro-fast`	image-to-video	5s, 10s	720p, 1080p	No aspect-ratio option is configured	No
`seedence-1-0-lite`	text-to-video, image-to-video	5s, 10s	480p, 720p, 1080p	text-to-video: 16:9, 4:3, 1:1, 3:4, 9:16, 9:21; image-to-video: no option	No

frames-to-video requires at least two image_urls; reference-to-video requires at least one. Seedance 2.0, Fast, and Mini accept optional video input for reference mode.

Credit pricing

Text-to-video and image-to-video use the same matrix unless noted. Seedance 2.0, Fast, and Mini are billed per second through FreeModel APIPod.

`seedance-2-0`

For every supported mode, the standard rate is 6 credits/second at 480p, 12 at 720p, 9 at 1080p, and 27 at 4k. The calculation is ceil(rate * duration_seconds). Example: 5s 720p = 60 credits.

For reference-to-video with video input, APIPod bills on (input_seconds + output_seconds). The configured rate is 4 / 7 / 6 / 13 credits/second at 480p / 720p / 1080p / 4k. Provide options.source_video_duration_seconds (sum of reference videos, capped at 15s). If it is omitted, Vidrush bills the 15s cap so the task cannot underpay.

`seedance-2-0-fast`

For every supported mode, the standard rate is 4 credits/second at 480p and 9 credits/second at 720p. The calculation is ceil(rate * duration_seconds). Example: 5s 480p = 20 credits.

For reference-to-video with video input, APIPod bills 0.6 × unit × (input_seconds + output_seconds). The configured rate is 3 credits/second at 480p or 5 credits/second at 720p, applied to that combined duration. Provide options.source_video_duration_seconds (sum of reference videos, capped at 15s). If it is omitted, Vidrush bills the 15s cap so the task cannot underpay.

`seedance-2-mini`

For every supported mode, the standard rate is 2 credits/second at 480p and 3 credits/second at 720p. The calculation is ceil(rate * duration_seconds).

For reference-to-video with video input, APIPod bills 0.6 × unit × (input_seconds + output_seconds). The configured rate is 1 credit/second at 480p or 2 credits/second at 720p, applied to that combined duration. Provide options.source_video_duration_seconds (sum of reference videos, capped at 15s). If it is omitted, Vidrush bills the 15s cap so the task cannot underpay.

`seedance-1-5-pro`

Resolution	4s	8s	12s	Audio-enabled price
480p	7	15	21	14, 30, 42
720p	15	30	45	30, 60, 90
1080p	30	60	90	60, 120, 180

The last column applies the configured 2x audio multiplier in the same duration order.

Seedence 1.0

Model	Configured pricing
`seedence-1-0-pro`	Standard quality: 4s = 14, 8s = 28, 12s = 42 credits
`seedence-1-0-pro-fast`	No detailed credit matrix is configured; the public catalog returns `16+ credits`
`seedence-1-0-lite`	480p: 5s = 10, 10s = 20; 720p: 5s = 20, 10s = 30; 1080p: 5s = 30, 10s = 40

seedence-1-0-pro currently exposes 5s and 10s as valid durations while its configured Standard-quality price entries are 4s, 8s, and 12s. Do not infer a price for that mismatch; inspect GET /api/v1/models before submitting a task.

MCP

Ask the MCP client for get_video_model before generate_video so it can select the correct Seedance mode and price.

Notes

Per-second models round the calculated price up with ceil.
Seedance 2.0, Seedance 2 Fast, Seedance 2 Mini, and Seedance 1.5 Pro expose audio: true in this family.
The model IDs intentionally use both seedance and seedence; send the IDs exactly as shown.
