How to make an Amazon product video with AI, in Amazon's exact specs

Step by step

1. Step 1

   Pick the placement first, because the rules differ

   Sponsored Brands video (shown in search results) takes 6–45 second videos, and Amazon recommends 20 seconds or less; sound is allowed but the video autoplays muted. Sponsored Products video needs at least 7 seconds, and its audio is removed. Both take horizontal 16:9 only (Amazon lists vertical 9:16 for Sponsored Products as coming in 2026). A video on your product detail page needs Brand Registry and is uploaded in Seller Central; check the current requirements there before you make one.

2. Step 2

   Generate in 16:9, not 9:16

   Cropping a vertical video to 16:9 throws away most of the frame, and Amazon rejects black or blurred bars on the sides. Generate the video horizontally from the start: in VIVID, choose 16:9, and describe the shot as "16:9, handheld smartphone-style video" so it still feels like a real person filmed it.

3. Step 3

   Show the product in use, large in the frame

   For Sponsored Products, Amazon asks for the product to fill at least half the frame and prefers videos of a person using it; videos that rely on someone talking to camera are rejected. Describe hands-on actions and close-ups: "drops frozen strawberries into the blender bottle, presses the button, the smoothie spins". This kind of video also works for Sponsored Brands and the detail page.

4. Step 4

   Make it work without sound

   Sponsored Brands videos start muted, and Sponsored Products videos have no sound at all. Show the benefit in the picture (before and after, the product working), and if a line of dialogue or a voiceover carries information, add it as a caption. Keep text and important details out of the lower-right corner, where Amazon places the mute button.

5. Step 5

   Convert the file to Amazon's specs

   Sponsored Brands accepts 1280×720, 1920×1080 or 3840×2160, H.264 Main or Baseline profile, and audio at 44.1 kHz or higher. Most AI generators don't output exactly that; VIVID's 720p 16:9 video, for example, is 1344×768 with 32 kHz audio. One ffmpeg command fixes all of it: ffmpeg -i in.mp4 -vf "scale=1280:-2,crop=1280:720,setsar=1" -c:v libx264 -profile:v main -b:v 4M -c:a aac -ar 48000 -b:a 128k amazon.mp4. It resizes to 1280 wide, trims a few pixels top and bottom (no bars), and re-encodes the video and sound.

6. Step 6

   Keep it honest and on-brand

   Use your real product (upload a product photo as a reference image), and don't show features it doesn't have. Don't present an AI person as a real customer giving a review. Keep the video in the marketplace's language, and avoid things Amazon commonly rejects: logos that aren't on the product, prices and discount claims, website addresses, and emojis in Sponsored Products videos.

Tips for testing

• Make two or three versions with different opening shots and run them in the same campaign; the first 2 seconds matter as much on Amazon as anywhere else.
• File names matter for Sponsored Products: Amazon asks for labeled file names, so name each file after the ASIN and the feature it shows.
• A short loop of the product in use, without dialogue, is the most reusable cut: it fits Sponsored Products, Sponsored Brands and the detail page.
• If you also run Meta or TikTok ads, make a separate 9:16 version for those instead of reusing the 16:9 Amazon cut.

What it costs

With VIVID you pay per generation: a 5-second 480p clip is about $0.045–$0.10, a 15-second 720p clip about $0.45–$1.00, and an ad image about $0.015–$0.033. Credit packs from $1, one-time, no subscription. New accounts get 10 free credits — enough for about 3 short clips or 10 images — and failed generations are refunded automatically. Live prices are on the pricing page.
