Capturing game video & uploading dilemma..

What does that have to do with not being able to upload a video I'm online and gaming perfectly fine just can't upload my video game captures

You can use OneDrive. You get 5GB of storage for free.

In the capture settings on the console, you can set it so that captures are automatically uploaded to OneDrive if you like. You can also manually upload multiple captures to OneDrive at once via the Captures app. Also, you can upload an individual capture to OneDrive via the Share menu.

Once uploaded, screenshots will appear in the Pictures\Xbox Screenshots folder inside your OneDrive folder, and videos will appear in Videos\Xbox Game DVR.

What you need to do is copy your captures to the captures folder on Windows 10, should be in your videos folder. Then launch the Xbox app, select captures, then select this pc, and your captures should be listed, select the capture you want to upload, and
give it a name, and choose the game it's for, and select upload. Once it is uploaded it will take a few hours to go on the xbox live feed.

You can upload video captured on 360 to youtube....its called an external capture card and they aren't THAT expensive.

I use a capture card because of this and another problem I encountered is that if you capture 4k HDR videos on external when you upload them to Youtube only the 4k aspect of it uploads but not the HDR and the video ends up looking weird
