Video Generation

Generate cinematic video clips using the Seedance 2.0 model.

Overview

Generate short cinematic video clips from text prompts or reference images using the Seedance 2.0 model.

Submit a video generation task using the Videos API:

cURL

1	curl https://api.alltoken.ai/v1/videos/generations \
2	-H "Authorization: Bearer $ALLTOKEN_API_KEY" \
3	-H "Content-Type: application/json" \
4	-d '{
5	"model": "seedance-2.0",
6	"prompt": "A serene mountain lake at sunrise, cinematic 4K",
7	"ratio": "16:9",
8	"duration": 5,
9	"resolution": "720p"
10	}'

model — "seedance-2.0"
prompt — text description of the desired video
ratio — aspect ratio: "16:9", "9:16", "4:3", "3:4", "21:9", "1:1", or "adaptive"
duration — length in seconds; -1 lets the model choose automatically
resolution — output resolution: "480p", "720p", or "1080p"
content — multimodal input array for image-to-video or references, for example { "type": "image_url", "image_url": { "url": "..." }, "role": "first_frame" }

Video generation is asynchronous. Poll for status:

cURL

$curl https://api.alltoken.ai/v1/videos/generations/{task_id} -H "Authorization: Bearer $ALLTOKEN_API_KEY"

The response includes status (queued, processing, completed, failed, expired, or cancelled) and a download URL when complete.
