The Xbox One captures game footage at 720p and 30 frames per second, Microsoft has confirmed.
That's irrespective of the source resolution, Marc Whitten, chief Xbox One platform architect, told IGN.
Xbox One launch title Forza 5, for example, outputs at 1080p and 60 frames per second, but Xbox One's in-built DVR captures clips at 720p and 30 frames per second.
As revealed last month, Xbox One records the last five minutes of your gameplay. For times when you can't stop playing (such as in the middle of an online session), Microsoft allows you to capture and immediately save the last 30 seconds of gameplay for editing later.
"The first thing you'll see with our game DVR is the integration of our Upload service on the console," Whitten explained.
"This service allows you to manage, edit, and share your content. Your clips are stored in the cloud. Also, you'll see games making 'magic moment' videos of your gameplay based on the game DVR functionality - all seamlessly integrated.
"You'll be able to see these clips in the Xbox One Guide, in your own game DVR collection, and when you are looking at gamercards on the system. You'll also see games take advantage of this platform capability and do interesting things to integrate captured game footage into the game experience itself."
Meanwhile, Whitten confirmed that Xbox 360 Avatars will transfer over to Xbox One, and include new options, such as the ability to do full-body HD gamerpics.
"We've moved from the 64x64 gamerpics on Xbox 360 to a full 1080p," Whitten added. "They are beautiful, and you are going to see some really cool hero moments, like when you login to see personalised views of your games and other content."
