Since the official launch of the Amazon Developer Portal, we have received tons of positive feedback regarding the developer registration and app submission process.  However, with the large volume of activity, it’s not surprising that developers have a few questions that are not directly answered in our FAQ.  We’ll take this opportunity to answer some of those questions:

Are you required to submit a video along with other multimedia content, such as icons and screenshots?

Although compelling videos can be helpful to customers when they are deciding on which app to buy, they are not required. 

The only multimedia files that are required are:

• Device icon (114x114px)
• Large icon (512x512px)
• A minimum of three screenshots (480x854px or 854x480px each)

The maximum size for each image is 3Mb.  More information about multimedia files can be found here. If you have submitted your app and see the status “Incomplete (Missing Multimedia)”, then it is likely that you did not submit one or more of the required images.  If you believe you have submitted all multimedia files and are still seeing this status, we encourage you to contact our support team.

What is the maximum video size that you can upload for an app? 

The maximum size for a video is 30Mb.  There is a 3Mb limit for video files submitted through the Developer Portal’s web console.  If you want to submit a video that is greater than 3Mb (but under 30Mb), please use your FTP account.  The process to create an FTP account and submit your app video is described here. 

What video formats do you support?  Your FAQ says MP4 H.264- so does this mean you don’t accept any other format?

We require your videos to be stored in an MP4 H.264 encoded format.  This is to ensure an optimal visual and performance experience for your customers.  Remember that these videos will not only be viewed on Amazon’s retail website, but also on mobile devices.  If you upload videos that do not meet the requirements outlined in our FAQ, there may be a delay in your submission review, or your video may not be included on your final detail page.

If you have any additional questions as you go through the Amazon Appstore submission process, please do not hesitate to contact our support team.
