Temu detail video up to 180 s: stitch 30 s clips with Timeline

A 180-second detail video is six 30-second Sume clips joined by one Timeline render. A search summary of Temu's partner documentation says the detail video allows up to 180 seconds and 300 MB in 1:1, 4:3 or 16:9 at 720p or higher; confirm on Temu's page.

The arithmetic

seedance-2.5 accepts 4 to 30 seconds and wan-3.0 accepts 2 to 30 seconds. 180 divided by 30 is six clips. If 300 MB means 300 million bytes, 180 seconds at that cap is about 13 Mbit/s on average, so check the rendered file size before upload.

Stitching with Timeline

Timeline 1.0 takes an audio spine plus ordered video[] slots. With no voiceover yet, audio.mode: "silence" declares the length. Every URL must be a media.sume.com artifact, and Idempotency-Key is required. Starts must increase, and video[0].start must be 0. Use hard cuts or short fades.

curl -X POST https://api.sume.com/v1/timeline-1.0/render \
  -H "Authorization: Bearer $SUME_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: temu-detail-001" \
  -d '{
    "audio": { "mode": "silence", "duration_seconds": 90 },
    "video": [
      { "source_url": "https://media.sume.com/artifacts/artf_demo/c1.mp4", "start": 0, "duration": 30 },
      { "source_url": "https://media.sume.com/artifacts/artf_demo/c2.mp4", "start": 30, "duration": 30 },
      { "source_url": "https://media.sume.com/artifacts/artf_demo/c3.mp4", "start": 60, "duration": 30 }
    ],
    "output": { "width": 1280, "height": 720 }
  }'

Scaling to 180 s

Extend video[] to six slots and set duration_seconds to 180. Timeline allows up to 1800 seconds and 200 slots. Docs say strategy: "single" with more than 12 slots is unsafe, which six slots avoid. Preflight with POST /v1/timeline-1.0/plan, which is unbilled and returns duration and estimated cost.

Consistency across clips

Separate generations will not match exactly. Give every clip the same product reference images and a similar prompt, and review the cuts before upload.
