After the video is online, you can change the association between the video and ASIN: go to the upload and manage video page. Then find the video that needs to be changed and replace it with a video, but the content after replacing it with a video should be reviewed. The review process is slow, about a week or even longer, so there are basically no special circumstances, so it is best not to change the video. Also asked to change the video. The video shall not exceed 90 seconds as far as possible, the video size shall not be greater than 100MB, and the video format shall be MP4.

Because Amazon's new products will continue to be optimized, it will definitely be able to change videos. One thing, the video quality of Amazon's new products is really good.
