Yeah, exactly. Just do what you wanted to do and then after doing it bring up the game dvr and there is an option to end a clip of varying length. So, for example, say I wanted to show off a lap in forza, I'd complete the lap, bring up game dvr, select end 5 minute clip here, and then it will save a recorded clip of the last five minutes. Unless you are unbelievably slow you should easily be able to capture what you wanted.
Yeah, I've done that. Or attempted to, I should say. It doesn't always work. [Bringing up] DVR will sometimes lag slowly or it will screw up. I tried it multiple times in MCC showing differences in Halo 2 Anni and it fucked up every time. But we're getting way OT here, lol.
Also, I'm talking about starting a video recording and then playing. Like PS4's double tap that let's my recording start right there, not hoping it starts where I first started playing. Bringing up DVR and grabbing the last 5 mins is less painful than trying to start a recording yourself.
