Windows 10 Xbox App Recordings Upload Option

As mentioned above, you should upload the video to Xbox Live first then you'll be able to edit it on a Windows 10 PC.

I guess this is the only option at the moment.

If you have a mobile game clip what you've recorded to your phone using a screen capture app or something like that, you can't upload that video to Xbox Live.

Sorry, but that's not the way it works. You can download, edit and upload back
to Xbox Live only those game clips that
you’ve recorded with the Game DVR feature.

Step 1: Upload the video to Xbox Live (what you want to edit)

Step 2: Once it's uploaded to the Xbox Live, download it to your Win10 PC via Xbox App

Step 3: Edit, trim and save the new game clip

• Edit and share game clips with Game DVR in the Xbox app on Windows 10

Step 3: Upload your edited video back to Xbox Live

Hi. Thanks for the link. When I open Game DVR on my Xbox (One), select the clip, then select "edit," I was never provided the options that link showed. It took me directly to the Upload Studio app download page. With that downloaded, it takes me straight
into the app. This is becoming such a headache!

the only other option is to download another 3rd party program or app that you like and that your processor can handle. a quick google brought me to this. winsupersite.com/.../how-use-windows-10s-screen-recording-utility

Hey Jason!

Thanks for reaching out to us today. Game clips on Xbox are recorded, edited, and shared from the Game DVR feature associated to the Upload Studio app. The Upload Studio app is the only way to upload and share clips that you recorded from Xbox or Xbox on
Windows 10.

As of right now, I don't think there is a way to convert or transfer your recorded files that are captured using your internal graphics card. All clips are captured using the Game DVR feature and then edited and shared from Upload Studio.

Look over our
Game DVR and Upload Studio on Xbox One article online that goes over how to record and share clips on Xbox.

Hope this helps!
