Crop tool for Captures

You could take a screen capture and then crop the pic and upload it that way.

Hello Dave H, I am an independent advisor and I would be happy to help you today. My name is Khaji

I understand your frustration. Xbox game clip editing is currently only available on Windows 10 devices, not consoles

Open the Xbox guide: Press the Xbox button on your controller to open the guide

Go to Capture and Share: Navigate right using the joystick to the Stream and Capture menu

Select Recent Captures: Use the 'A' button to select Recent Captures

Choose the clip you want to edit: If your clip is not recent, select Show all and then choose the clip you want to edit.

Select Crop: To edit, select More actions (…) > Crop, and then use the on-screen controls to edit and save.

Thank you very much for your patience and understanding! If you need anything else, don't hesitate to contact us again.

There would be a delay introduced by the capture card making playing very difficult.

If you want to spread out the picture from the Xbox One across the monitors, remember that it would need to crop 1/3rd off the top and bottom, which is far greater than the 'action safe' and 'title safe' areas assumed for console games and video. They're
designed assuming only 5-8% of each edge may be cropped by the display.

If you don't mind me asking, what is the goal of the setup?

Hello again, maybe they use other tools, softwares to do the screen`s captures.

Are you using any additional tools to record? softwware or hardware such a video capturer or something like that?
