Amazon is a customer-obsessed company and captions help ensure a consistent viewing experience for all customers, including those who might be hearing-impaired, are non-native English speakers, or prefer to view videos without sound. Approximately 30% of all viewers use closed captions and 80% of those viewers aren't hearing-impaired. For these reasons closed captions are becoming a requirement on most professional video streaming sites. Caption files are an investment in the quality of your content and once created are yours to keep and use on any video platform.
What are the language requirements for publishing?
The Catalog Listing Language for a title must be one of a location's supported languages to publish to that location (English for the United States and United Kingdom, German for Germany, and Japanese for Japan).
The Catalog Listing Language for a title must be the same as either the audio or caption language.
Additionally, the Title Metadata Language for a title must be the same as either the audio or caption language.
How do I create captions for my titles?
Creating closed captions files is a technical process that might be challenging for some content providers. We recommend engaging a 3rd party service to assist in the creation of high-quality captions files. The following is a sampling of providers that can assist you with video captions. Amazon isn’t affiliated with, nor endorses any specific provider.
Prime Video accepts a variety of caption formats. Please review the information in the help topic to help you create acceptable captions files.
We recommend that you submit pop-on captions (captions that appear one to three lines at a time). If you provide roll-up captions, we must convert them to pop-on, which adds opportunity for error.
What if my title has no dialogue?
If a title contains no dialogue or has extended scenes with no spoken content, captions should include a description of the foreground or background audio elements. Extended silent scenes should be captioned with [no audio]. For background music, if the music is instrumental (no lyrics), use descriptive words [in brackets] to accurately convey the mood and tempo of music. If music contains lyrics, caption the lyrics verbatim. The lyrics should be introduced with the name of the artist and the title in brackets. In the event that lyrics are unclear or in another language, use a descriptive caption to indicate that to the viewer.
All captions files must conform to match the video source.
Closed captions are timed text that includes both spoken dialogue and atmospherics for the deaf and hard of hearing. There are many different types of closed caption file formats that you can choose from when creating your captions files. The following closed captions formats are accepted by Prime Video:
English captions are required for all titles published in the United States.All timecodes contained in a closed captions file must appear in linear (sequential) order.
Subtitles are timed text assets that provide on-screen text of the program dialogue. Like closed caption formats, there are several types of subtitle file formats that you can choose from when creating the files. The following subtitle formats are accepted by Prime Video:
