Amazon on Friday announced Prime Video Ultra, a subscription that replaces its existing ad-free offering in the US, starting on April 10. The subscription is $5 per month and removes commercials for customers who have the default, ad-supported version of Prime Video through a standalone subscription or Prime membership.

Existing ad-free customers who pay an extra $3 per month to stream without ads will become Ultra subscribers and pay $2 more in April but gain “advanced viewing features,” according to an email from Amazon obtained by CNET. These added features include:

• 4K UHD video
• 100 downloads (increased from 25)
• Five simultaneous streams (increased from three)

The default version of Prime Video will offer 50 downloads and four concurrent streams, according to an Amazon blog post. A Prime Video standalone subscription costs $9 a month, and a Prime membership that includes a Prime Video benefit costs $15 a month or $139 a year. If you get Prime Video through an annual Prime membership, you can choose to sign up for a Prime Video Ultra annual plan for $46.

Prime Video Ultra subscribers may still see ads on live TV and events, as well as on other select ad-supported content and add-on subscriptions, Amazon wrote. Read more about the Prime Video streaming service and the perks you get with a Prime membership.
