Amazon Fire tablet video ad specs: 15 s max, 16:9 or 16:10, audio

Amazon's templated Fire tablet video ads take a video of at most 15 seconds, at least 1280x720, 16:9 or 16:10, as .mp4 under 500 MB, with AAC audio at 48 kHz and at least 128 kbps. Audio is required, and the headline is limited to 50 characters. Read 2026-09-29.

What does the page list?

These are the values Amazon's page lists for templated Fire tablet video ads.

What can Sume produce?

16:9 at 720p or 1080p fits, with duration up to 15 seconds in a single request on seedance-2 (4 to 15 s) and seedance-2.5 (4 to 30 s, so keep it at 15 or less). No Sume video model lists 16:10, so use 16:9. A Timeline output of 1280x800 would be 16:10 (even integers 256 to 2160), though sources are cropped or padded to it.

Set generate_audio to true (or leave it out on models with audio) since the spec requires sound.

    "duration": 12,
    "resolution": "720p",
    "aspect_ratio": "16:9",
    "generate_audio": true
  }'

How do I check the audio?

Sume does not list sample rate or audio bitrate controls. Probe the result with POST /v1/video-inspect for the audio stream details before upload.

What are the limits of this answer?

Sume cannot promise 48 kHz AAC output; verify it. Amazon's page applies to templated Fire tablet ads only.
