The Xbox One's Game DVR functionality will automatically record the moment a player unlocks an in-game Achievement, Xbox Australia platform category lead Adam Pollington confirmed in a new interview with YouTube user ChampChong (via Kotaku).

Previously, players would have to set up an external capture system to save a moment such as this.

The Game DVR feature for Xbox Onecontinually records around five minutes of footage in the background, which players can then process through Microsoft's Upload studio and share with friends. Captured content can be shared only through Xbox Live at launch, with support for social networking sites like Facebook coming later.

Sony's PlayStation 4 will automatically record the last 15 minutes of gameplay, which players can then edit and share with their friends through the DualShock 4's new "Share" button. It is not clear if the PS4's video recording functionality will capture the moment a player unlocks a trophy.

The Xbox One and PS4 launch next month. According to a report from the International Data Corporation, the PS4 will outsell the Xbox One at launch due to a variety of factors, including its lower price point.

If I understand this correctly, they will automatically save the video segment that corresponds to you getting the Achievement. If that's so, it's a pretty neat idea.

yeah that's cool. at the end of the game, when the credits roll they could show you a retrospective, how you killed the bosses and killchains, et cetera.
i love this idea. make this! @sony: please copy paste!

But... I don't wanna record my achievements:

The Hunter: Kill a sweet, innocent, fluffy bunny rabbit (5 points)

The Swinger: Take part in a debauched bedroom party with several participants (5 points)

Warm Coffee: Successfully date a girl to be invited into her house (5 points)

Sounds neat for the hunters, but hopefully this can be turned off, I dont want to waste hard drive space on epenis videos.

I hope it's smarter than just saving the 30 seconds before the achievement pops up.

The vast majority of achievements nowadays are for collecting things, and a montage showing you collecting them would be much better than just a video of the last one you collect.

I really do like the idea though and will look into it.

MS clarified that it is up to the devs... only the selected achievements will have this feature.

i think its saved to the cloud

oh... then save these videos! all of em! :P
