Volcengine API

POST https://ark.cn-beijing.volces.com/api/v3/videos/generations
Authorization: Bearer <API_KEY>
Content-Type: application/json

{
  "model": "Doubao-Seedance-2.0",
  "prompt": "<compiled plain-text prompt>",
  "duration": 8,
  "aspect_ratio": "16:9",
  "resolution": "1080p",
  "seed": 42
}

Rules

• Never send raw JSON schema — compile to plain text first.
• seed is optional; omit for variation, set for reproducibility.
• Check status field in response: queued → processing → completed | failed.
• Poll at 5 s intervals; timeout after 120 s.

Post-Processing Chain

1 · Upscale

• Tool: Topaz Video AI · Real-ESRGAN · ffmpeg scale=iw*2:ih*2
• Target: 720p → 1080p (standard) · 1080p → 2K (premium)

2 · Frame Interpolation

• Tool: RIFE v4.x · DAIN
• Standard: 24 fps → 60 fps (smooth motion)
• Fight / fast action: 24 fps → 120 fps

3 · Color Grade

• Tools: DaVinci Resolve · FFmpeg LUT
• Workflow: normalize exposure → apply LUT → mask-lift shadows → finalize.
• LUT slots: Rec.709 (web) · Log-C (archive).

4 · Audio Mux

• Merge generated stereo audio with video: ffmpeg -i video.mp4 -i audio.mp3 -c:v copy -c:a aac -shortest out.mp4

5 · Metadata Clean

• Strip generation metadata before distribution: exiftool -all= output.mp4
• Rename: {project}_{shot}_{take}_{date}.mp4

6 · Composite (optional)

• Layer generated clips in After Effects / DaVinci Fusion.
• Match color temperature across cuts before export.
