Xbox can't upload game clips to Xbox live?

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

Were these clips uploaded to Xbox live or are they meant to be local to your Xbox?

If they are local did you ever factory resetyour Xbox (complete reset)?

Have you checked you are searching locally not on Xbox live as it defaults to Xbox live only

I know if you are uploading to Xbox live sometimes some disappear but it's not usually one game its normally the oldest clips first and ad you have clips from 2 years ago this is unlikely

Did you delete clips from your Xbox after upload as I'm pretty sure this clears the whole clip from both the xbox servers and your xbox, not just the Xbox

I'm having the same problem on the One S. First i thought of giving it some memory space and deleted one clip. The clip would not delete. today it shows up as a thumbnail-less clip that can't be played. I can't upload any videos, the xbox tells me it's uploading
and it tells me the clip has been uploaded to live, but when i check theres nothing there. On the mobile App I get the notification that a clip has been uploaded and I can view the clip on my phone, but if I try to share or save the clip it says a problem
occurred. As soon as I leave the clip page, it disappears from the captures tab on the app. The clip I deleted on my xbox doesn't show up on my Mobile App, thats a good thing.

People are being banned for uploading video clips that they are swearing in on the Xbox One. Still a bit much IMO, but they're not just randomly banning people because they're swearing in online matches.

Hey there Andy,

I'd be happy to provide some input.

Just to make sure, I would suggest you launch the Upload Studio app to confirm those clips were successfully uploaded to Xbox Live. This article

here explains how to do that.

You'll be able to see the clips you made on the old Xbox that were uploaded to Xbox Live since you are using the same account that made the clips originally.

Once you confirm that the clips in question have been uploaded to Xbox Live, then it may be due to the clips not synchronizing to the app as you mentioned.

A
powercycle on the console may help to re-sync your Xbox, and the clips that are on the Xbox, to the Xbox Live Servers.

Let us know if any of that helps!
