Amazon has two video specs that matter for a product. For listing (detail page) videos, Amazon's seller blog (May 12, 2025) lists ".mov or .mp4", "Up to 1080p", "Maximum 5 GB" and a length line of "Between 1 and 12 minutes". For Sponsored Brands video ads, the Amazon Ads spec page (checked 2026-11-09) asks for "Between 6 and 45 seconds", "16:9 (square pixel) only", 1280x720, 1920x1080 or 3840x2160, "500MB or less", H.264 or H.265, and a "Minimum 1 Mbps" bit rate with 4 Mbps or more recommended. The second spec is the one AI clips most often miss, and the miss is usually bitrate or shape, not length.
For the step-by-step listing video board, see how to make an Amazon listing video with AI. This page is the spec, quoted, and the 8frame settings that meet it. For which shots to put in the video, the product video template has a five-shot structure.
Listing videos: what Amazon's seller blog says
From "When customers can't touch, let Amazon product videos convince them" on sell.amazon.com (May 12, 2025):
| Item | Amazon's wording |
|---|---|
| Format | "In .mov or .mp4 format" |
| Resolution | "Up to 1080p" with the highest available quality recommended |
| File size | "Maximum 5 GB" |
| Length | "Between 1 and 12 minutes" |
| Thumbnail | "System-generated or custom", .jpg, .png, .gif or .bmp |
| Placement | to appear in the main media block, the listing must have "fewer than six images" |
| Review | "Amazon will review your video to ensure it meets community guidelines." |
On eligibility, the same article says you do not need to have your brand enrolled with Amazon first; you need a Professional selling account, live listings and "at least three months of selling history." The upload screen is inside Seller Central, behind sign-in; check the limits there on the day you upload.
A post in the Seller Forums from an Amazon account, dated about three years ago, adds content advice: "Don't use commercial-like videos or promotional and paid testimonials" and keep content "informative, demonstrative, and above all else, authentic." It is a forum post, not a policy page, but it points the same way as the FTC rules: show the product, do not stage fake customers.
Sponsored Brands video: the full spec
From advertising.amazon.com, Sponsored Brands video ad specs (checked 2026-11-09):
| Item | Amazon's spec |
|---|---|
| Duration | "Between 6 and 45 seconds", 20 seconds or less highly recommended |
| Aspect ratio | "16:9 (square pixel) only" |
| Dimensions | "1280x720, 1920x1080, or 3840x2160px" |
| File | ".MP4 or .MOV", "500MB or less" |
| Frame rate | "23.976, 23.98, 24, 25, 29.97, 29.98, or 30fps" |
| Scan | "Progressive" |
| Codec | "H.264 or H.265", profile "Main or Baseline" |
| Video bit rate | "Minimum 1 Mbps", 4 Mbps or higher recommended |
| Audio | "PCM, AAC, or MP3", "Stereo or mono", "Minimum 96 kbps", "Minimum 44.1khz" |
| Layout | no horizontal or vertical black, colour or blurred bars; keep text and key information out of the lower right corner |
| Content | "suitable for a general audience", in the language of the marketplace |
The spec mapped to 8frame settings
Every generated video on 8frame is the provider's own file: H.264 in MP4 at exactly 24 fps, not re-encoded by 8frame. So codec, container and frame rate already meet the Sponsored Brands spec. The questions are shape, resolution, bitrate, length and sound.
| Spec item | What meets it on 8frame | What does not |
|---|---|---|
| 16:9 only | a 16:9 start still on a Kling node (Kling follows the still's shape), or 16:9 picked on Seedance | a 9:16 clip placed on a 16:9 canvas (that is a bar, which Amazon rejects) |
| 1280x720 minimum | 720p models (Seedance, Kling v3 Standard, Kling O3) sit exactly on the floor; 1080p models (Kling 2.6 Pro, Kling 2.5 Turbo Pro, Happy Horse at 1080p) give headroom | 480p tiers |
| 3840x2160 | nothing: no video model on 8frame outputs 4K, and there is no video upscaler | |
| Bit rate, 4 Mbps recommended | measured medians: Kling 2.5 Turbo Pro 1080p 26.3 Mbps, Kling 2.6 Pro 1080p 24.1, Kling v3 Standard 720p 17.2, Happy Horse 1080p 16.0, Seedance 2.5 720p 12.3 | Seedance 2.0 720p 4.7 Mbps median (middle half 3.9 to 5.2, so some files fall under 4); Gemini Omni Flash 720p 2.4; any 480p tier (Seedance 2.0 480p 2.5) |
| 6 to 45 seconds | one long take on Seedance 2.5 (4 to 30 s) or Wan 3.0 (2 to 30 s); otherwise several clips joined on the Video Editor timeline | a single 5 second clip (under the 6 second minimum) |
| 500 MB | every model: a 10 second clip at the highest measured median (Kling 2.5 Turbo Pro) is about 33 MB | |
| Audio track | models that write one: Seedance 2.5, Hailuo H3, Happy Horse, Gemini Omni Flash (all files in our sample had a track); Kling v3 Standard with sound on | the Montage node's output, which has no audio track at all; Kling 2.5 Turbo Pro and O3 files, which had none |
Two consequences people do not expect:
- A 5 second clip is too short. Sponsored Brands needs at least 6 seconds. At 1080p, Kling 2.6 Pro at 10 seconds (189 with sound) or Kling 2.5 Turbo Pro at 10 seconds (95) clear it in one take. At 720p, Kling v3 Standard takes any whole second from 3 to 15, so 6 seconds or more works too.
- The cheapest 720p tier may fail the recommended bitrate. The spec's hard minimum is 1 Mbps, which every model clears, but the 4 Mbps recommendation is missed by some Seedance 2.0 720p files and by Gemini Omni Flash. If Amazon flags quality, re-run on a model with a higher median bitrate.
What changes on the board for Sponsored Brands
The board itself (reference photos, hero still, motion, export) is in how to make an Amazon listing video with AI. For a Sponsored Brands cut, change four things on it: make the start still 16:9 so the Kling node inherits that shape; run the motion at 1080p on Kling 2.6 Pro or Kling 2.5 Turbo Pro; build 15 to 20 seconds on the Video Editor timeline (exports there cost no credits) instead of the Montage node, whose file has no audio track; and keep captions out of the lower right corner.
The Video Editor renders a new file on export. We have not measured its bitrate, so check the exported file's properties against the 1 Mbps minimum before upload.
What about AI content on Amazon?
Neither page quoted above mentions AI. We did not find an Amazon policy page on AI video that we could fetch and quote, so here is practical advice rather than a policy quote: show the real product with its real label, size and colour; do not show results the product does not deliver; do not present a generated person as a customer. The FTC rules covered in do you have to disclose AI-generated ads apply to Amazon ads like any other US ad.
FAQ
What aspect ratio does Amazon require for Sponsored Brands video? "16:9 (square pixel) only", at 1280x720, 1920x1080 or 3840x2160. Vertical clips with bars are rejected.
Can I upload a 720p AI clip to Amazon? For Sponsored Brands, 1280x720 is an accepted size. For listing videos, Amazon's seller blog says up to 1080p. 720p models on 8frame (Seedance, Kling v3 Standard) produce 720p files.
Can I make a 4K Amazon video on 8frame? No. No video model on 8frame outputs 4K and there is no video upscaler. 1920x1080 is accepted by both specs.
How long should a Sponsored Brands video be? 6 to 45 seconds, and Amazon recommends 20 seconds or less.
Why was my clip rejected for no audio? We cannot see Amazon's review reasons, but if you joined clips with the Montage node, the file has no audio track while the spec lists audio requirements. Rebuild it on the Video Editor timeline with a sound layer.
