Amazon Sponsored Brands Video Specs: Length, Size, and Requirements (2026)

Amazon Sponsored Brands Video runs up to 45 seconds, in 16:9 landscape at 1920x1080, delivered as an MP4 or MOV up to 500 MB at 1 Mbps or higher, with 6 to 20 seconds recommended and captions effectively required because the video auto-plays on mute. Those are the numbers you need. The rest of this guide covers the details that actually get ads approved and performing: the accepted resolutions, the creative policy that trips sellers up, and how to produce compliant video without a studio.

The full Sponsored Brands Video spec, in one table

Here is the complete technical spec so you can render once and pass review the first time.

Two of these matter far more than the others. The length should sit near the short end, because a 15-second video holds completion rate and Amazon shoppers decide fast. And captions are effectively mandatory, not optional, because the video auto-plays with the sound off and the message has to land on the screen.

The creative rules that get Sponsored Brands Video rejected

Most rejections are not about resolution, they are about policy. Amazon's creative rules for Sponsored Brands Video are stricter than Meta or TikTok, and the same handful of mistakes come up again and again:

• No burned-in pricing or discounts. Prices change and Amazon will not approve time-limited claims baked into video.
• No competitor names or logos, and no comparative claims you cannot substantiate.
• No Amazon branding or anything implying Amazon endorses the product.
• No customer reviews or star ratings presented as Amazon's own.
• No blank or black frames at the start or end, and no letterboxing to force a different aspect ratio.
• No claims unsupported by the listing, including health or performance promises.

A straightforward product demo avoids nearly all of these by design. Show the product working, describe what it does in language you can back up, and keep pricing and competitors out of the frame.

The three-second rule decides your performance

Spec compliance gets your ad live; the opening decides whether it works. Because Sponsored Brands Video auto-plays muted in search results, a shopper reads the first frames rather than hearing them. If the product is not visible with a caption by the three-second mark, they scroll past. The highest-performing videos put the product on screen immediately, open with a concrete hook, and use captions to carry the whole message. A slow logo intro is the single most common way to waste the slot.

How to produce a compliant video without a studio

You do not need a production crew to meet these specs. A UGC-style demo, a real-looking person holding and using the product, satisfies the format and tends to outperform polished brand video because it reads as authentic. The challenge is producing it at the right shape and volume, since you also want vertical cuts for Amazon Inspire and off-Amazon social.

Generating the video from your listing solves both. An Amazon video ad generator reads your product page, writes a short script grounded in the actual product, and renders a captioned 16:9 video that meets the Sponsored Brands spec, plus a 9:16 version for Inspire and social from the same script. That keeps you compliant and covers every placement in one pass, at a few dollars per clip instead of a few hundred.

Keeping the numbers straight for your account

As your Sponsored Brands campaigns scale, the reporting and reconciliation grow with them. Amazon's disbursement statements, fees, and ad spend add up across marketplaces, and it helps to turn those payout statements into a clean spreadsheet so your margins stay visible rather than buried in PDFs. Compliant creative and clear numbers are the two halves of a Sponsored Brands program that actually stays profitable.

Frequently asked questions

What is the ideal length for Sponsored Brands Video?

Six to 20 seconds, even though the format allows up to 45. Shorter videos hold completion rate, and Amazon shoppers are close to a decision, so a tight demo outperforms a long one. Lead with the product and get the key message on screen in the first few seconds.

What aspect ratio does Sponsored Brands Video require?

16:9 landscape, recommended at 1920x1080. Do not letterbox a vertical video to fake it, since blank bars can get the ad rejected. If you also want to run Amazon Inspire or off-Amazon social, render a separate 9:16 vertical cut from the same script.

Does Sponsored Brands Video need audio?

Audio is recommended but the video plays muted by default, so it cannot carry the message. Burn captions into the video and design it to work with the sound off. Treat audio as a bonus for the minority of viewers who unmute, not as the primary channel.
