The Xbox One's Game DVR feature will not automatically record every Achievement a player unlocks, Microsoft director of product planning Albert Penello has clarified on NeoGAF.
"It won't be automatic for every Achievement. It's a feature that developers can unlock for achievements, OR, for instance, have hidden in the game for doing something cool or discovering something hidden," Penello said. "Basically, we allow developers access to Game DVR and they can put conditions on an automatic recording."
"But not every Achievement will automatically be recorded," he added.
It was previously said by an Xbox Australia representative that the Xbox One would in fact automatically record the moment a player unlocks all achievements.
Separately, a Microsoft representative provided a statement with more insight into the ways in which content can be captured on Xbox One using Game DVR.
"Xbox One keeps a rolling record of your most recent gameplay, and there are two main ways for this video to be captured by Game DVR," the representative said. "First, game developers mark 'greatest clips' that happen within the game that represent fun and interesting moments within gameplay, such as when you unlock certain Achievements. Additionally, you can also issue commands, with either your voice or the controller, to capture interesting moments you would like to record or that just happened."
The Game DVR feature for Xbox One continually records around five minutes of footage in the background, which players can then process through Microsoft's Upload studio and share with friends.
