Amazon Fire TV inline video ad specs: 10 to 30 s, 16:9, 960x540 min

Amazon's Fire TV inline video spec asks for 10 to 30 seconds of 16:9 video at 960x540 or larger, up to 500 MB, with video bitrate of at least 2,000 kbps and audio of at least 128 kbps in two or more channels. Read 2026-09-29.

What does Amazon list?

Accepted formats are AVI, DV, MOV, MP4, MPEG and M4V. Video codecs include H.264, MPEG-4, MPEG-2, H.265/HEVC and ProRes; audio can be AAC, PCM or MP3. Text overlays should be at least 64 pixels.

How do I ask Sume for it?

16:9 is a documented aspect ratio; confirm each model lists it in supported_aspect_ratios from GET /v1/videos/models. Choose 1080p to clear 960x540, and a duration of 10 to 30 seconds. seedance-2.5 lists 4 to 30 seconds. Generated audio is on by default where the model supports it.

curl -X POST https://api.sume.com/v1/videos \
  -H "Authorization: Bearer $SUME_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: fire-tv-inline-001" \
  -d '{
    "model": "seedance-2.5",
    "prompt": "A barista pours latte art, close-up, slow push-in",
    "duration": 15,
    "resolution": "1080p",
    "aspect_ratio": "16:9"
  }'

What about bitrate and audio channels?

Sume does not list bitrate or channel-count controls. If you assemble in Timeline, sound comes from its audio spine (default output is 1080x1920, so set output.width and height). Probe the final file with POST /v1/video-inspect before you submit.

What are the limits of this answer?

Sume does not upload to Amazon Ads. This page covers the Fire TV inline spec only; other Amazon placements are in the linked posts.
