Xbox recording
So I can record 1 hour max with the game DVR of Xbox. If i have a run of 1 hour and 30 minutes for example can i mix the two clips of the run in one with a video editor?
You could ask the moderators of the game you are running for that question. If you cannot, then just use a mobile device and set up your phone on a table or something
Yes, it's possible. You'll be needing a capture card to connect your Xbox to your pc and use OBS or any other screen capture software to record your game. Then later edit on Filmora or other free video editing software like VideoPad, VSDC, Hitfilm Express, or any available option you currently have.
