Amazon's Prime Day video advice: product in 2 seconds, sound off
Amazon Ads' Prime Day guide says show the product in the first two seconds and design for sound-off. How to add captions and test the opening with Sume.

Amazon Ads' Prime Day strategy guide tells advertisers to open with the product in the first two seconds, design video for sound-off viewing, and use text overlays and captions. Both pieces of advice are things you can test on a finished file. Sume's video captions endpoint adds the text, and video frames pulls the frame at two seconds so you can look at what a viewer sees.
The advice as Amazon states it
The guide also says Amazon's free Video Generator makes 6 to 15 second videos and that video can be added to Sponsored Products without extra budget. That is Amazon's tool; this post is about checking your own clip.
| Amazon advice | Check |
|---|---|
| Product in the first two seconds | Frame at 0s and 2s shows the product |
| Design for sound-off | Message is in on-screen text |
| Use text overlays and captions | Burn authored cues with video captions |
Run the two checks
For the opening, request frames at 0 and 2 seconds with video frames. If the product is not in the 2-second frame, trim the intro with video trim so the clip starts later.
For sound-off, add a short line on screen. The video captions endpoint takes authored cues and a style such as punch, and a silent clip works since authored cues skip speech-to-text. At $0.20 per job for up to 60 seconds, one job per variant is the unit to budget.
- Trim dead lead-in time before the product appears.
- Keep each on-screen line short enough to read in one second.
- Compare captioned and clean versions before choosing.
Limits
The two-second advice is Amazon's guidance, not a rule that is enforced by a file check. Sume cannot see how your ad performs, and a trimmed clip must still meet Amazon's length minimum for the ad type you use. Read the ad type's spec page before you export.
