Amazon product video shows in the main block only under six images

Amazon's seller guide says a shoppable video appears in the main media block only when the product has fewer than six images. If you upload a six-image gallery, the video does not take that slot. Decide the image count before you spend on the clip. The rule comes from Amazon's product video guide, read 2026-10-03.

The rule and the spec around it

The guide gives the file and display rules in one place. The rule that most affects planning is the image count.

The tradeoff: image five versus the video

A listing with five images and a video gets the video in the main media block. A listing with six or more does not. So the sixth lifestyle image has a cost: it removes the clip from the most visible placement. If you are generating images in bulk, cap the gallery at five for any ASIN where the video is the priority.

The guide describes the main media block only. It does not say where a video goes when the product has six images, so do not assume a fallback location. Check a live listing after approval.

Build the pair on Sume

Generate the five stills first with Sume's image API and use one of them as the first frame for the clip, so image and video match. The video generation API accepts frame_images with a frame_type of first_frame for image-to-video, on models whose supported_frame_images lists it.

Note the length mismatch. Amazon's minimum is one minute, and a single generated clip is far shorter: models in Sume's catalog top out at 15 seconds, with a few reaching 30. Reaching one minute means assembling several clips on the timeline, whose audio.duration_seconds runs from 1 to 1800 seconds.

Checklist before upload

• Count the ASIN's images: five or fewer if the video must lead.
• Confirm the clip is at least one minute and at most 12.
• Export .mp4 at 1080p or lower.
• After approval, wait up to about three days and then check the listing.
