Viewing Period: For rental videos, you'll typically have 48 hours to finish watching the video once you have commenced streaming or downloading, provided that in any event you must finish watching the video prior to expiration of the applicable expiration window, which is typically 30 days from your payment of the rental fee. The length of this window can be found on the detail page or on a link from the detail page, such as the "Learn more about renting and buying" link on website detail pages.
Downloading: Many third-party add-on video subscription titles are also available for temporary download on compatible devices such as Fire tablets (other than Kindle Fire 1st Generation) and Android and iOS devices. For a list of compatible devices enabled for downloads, visit the Download Prime Video Titles page on the website you are using the access Amazon Prime Video at the following links, PrimeVideo.com, Amazon.com, Amazon.co.uk, Amazon.de or Amazon.co.jp (device compatibility may vary by location). The detail page for each third-party add-on video subscription title indicates whether the title is available for download. You can download available titles to only two devices at one time. If you have already downloaded a title to two devices, you will need to delete it from one of them before downloading to another device. We set a maximum number of titles that can be downloaded at a time across Prime or Prime Video and third-party add-on video subscriptions titles across all devices associated with your Amazon account which may vary based on your location and other factors. While not all third-party add-on video subscription titles are available for download, the same videos may be available for rental or purchase from Amazon Prime Video, which may then be downloaded to compatible devices.
