Supports text-to-video (bytedance-seedance-2-0-text-to-video-fast) and image-to-video (bytedance-seedance-2-0-image-to-video-fast). Use when the user specifically asks for Seedance 2.0, wants native audio with the video, realistic physics, director-level camera control, or 4–15 second clips up to 720p. metadata {\"author\":\"eachlabs\",\"version\":\"1.0\"} ByteDance Seedance 2.0 (Fast) ByteDance Seedance 2.0 on the EachLabs Predictions API. Seedance 2.0 generates cinematic video with native synchronized audio (sound effects, ambient sound, lip-synced speech), realistic physics, and director-level camera control. Two model slugs: Slug Category Use bytedance-seedance-2-0-text-to-video-fast Text to Video Generate a video from a prompt bytedance-seedance-2-0-image-to-video-fast Image to Video Animate a starting frame (optionally to an end frame) The \"Fast\" tier prioritizes rapid turnaround for high-throughput pipelines while keeping the family's character consistency and physics. When to use User asks for \"Seedance 2.0\", \"ByteDance video\", or wants a Seedance-style look. Native audio required in the same pass (dialogue, SFX, ambience) — no separate TTS/lipsync step. Cinematic motion, realistic physics, or director-level camera language (\"slow push in\", \"rack focus\"). Durations of 4–15 seconds at 480p or 720p. Image-to-video with an end frame to control where the clip lands. For a wider video-model comparison (Veo, Kling, Sora, Pixverse, Hailuo, etc.) see eachlabs-video-generation . Authentication Header: X-API-Key: <your-api-key> Set the EACHLABS_API_KEY environment variable. Get your key at eachlabs.ai/dashboard/api-keys . Prediction Flow (Recommended) Check schema — GET https://api.eachlabs.ai/v1/model?slug=bytedance-seedance-2-0-text-to-video-fast (or the i2v slug). POST https://api.eachlabs.ai/v1/prediction with model , version: \"0.0.1\" , and input . Poll GET https://api.eachlabs.ai/v1/prediction/{id} until status is \"success\" or \"error\" , or use a webhook. Extract the video URL from output (string). Quick Start — Text to Video curl -X POST https://api.eachlabs.ai/v1/prediction \\ -H \"Content-Type: application/json\" \\ -H \"X-API-Key: $EACHLABS_API_KEY \" \\ -d '{ \"model\": \"bytedance-seedance-2-0-text-to-video-fast\", \"version\": \"0.0.1\", \"input\": { \"prompt\": \"Cinematic slow push-in on a lone astronaut standing at the edge of a Martian canyon at dusk, dust drifting across their boots, distant wind, subtle helmet reflections\", \"resolution\": \"720p\", \"duration\": \"6\", \"aspect_ratio\": \"16:9\", \"generate_audio\": true } }' Typical processing time: ~120 seconds .

Return 2xx within 30 seconds. Parameters (both slugs share most of these) Parameter Type Required Default Options Description prompt string Yes — — Text prompt. For i2v, describes the motion/action; supports timeline prompting and dialogue lines for native audio. image_url string Yes (i2v only) — JPEG / PNG / WebP, max 30 MB Starting frame. Publicly reachable HTTPS URL. end_image_url string No (i2v only) — JPEG / PNG / WebP, max 30 MB Final frame; model interpolates between image_url and this. resolution string No 720p 480p , 720p 480p = faster/cheaper, 720p = balanced. duration string No auto auto , 4 … 15 Clip length in seconds. auto lets the model pick from the prompt. aspect_ratio string No auto auto , 21:9 , 16:9 , 4:3 , 1:1 , 3:4 , 9:16 For i2v, auto infers from the input image. generate_audio boolean No true — Synchronized SFX, ambience, and lip-synced speech. Cost is the same whether on or off. seed string No — — Reproducibility hint — results may still drift slightly. end_user_id string No — — Your end-user identifier. Pricing Dynamic, charged per second of output video : Resolution Rate 480p $0.1129 / second 720p (default) $0.2419 / second Audio generation does not change cost. A 6-second 720p clip ≈ $1.45; a 10-second 480p clip ≈ $1.13. Prompt Tips Timeline prompting : sequence beats with time or cut words — \"Wide shot: … Cut to close-up: … Finally: …\". Seedance 2.0 respects temporal structure better than single-sentence prompts. Dialogue with native audio : write the line in quotes and describe the speaker (\"Weathered British male narrator, 50s, calm authoritative voice, says: …\"). Lip-sync and ambience are generated in the same pass. Camera language : use real film vocabulary (\"slow push-in\", \"rack focus\", \"dolly left\", \"handheld\", \"crane up\"). The model follows director-level cues. Physics cues : mention weight, momentum, and material interactions (\"dust scatters as boot lands\", \"fabric settles after the spin\") to unlock the realistic-physics behavior. Rate Limits & Limits Limit Value Create requests 100 / minute per key Concurrent predictions 10 per key File inputs Publicly reachable HTTPS URLs only (JPEG/PNG/WebP, max 30 MB).
