What is the quickest way to download all of your captures from Xbox Live to a PC?

The best way to keep those clips is, install the Xbox app on your laptop or pc. Then on your console go to your captures and upload them to one drive and upload them to live. Then go to the Xbox app on pc or laptop click on the captures and scroll through
what is live and download the clips to your pc or laptop in a file.

Game pics/captures that haven’t had any views or engagement may be deleted at some point, you might want to back up your pics. If you wish to keep certain captures permanently, You should save them to OneDrive or an external drive for example. I will list the steps below regarding this matter. Also if you have reached capacity for storage of captures on Xbox Live, it will delete the oldest ones first to make room for the new ones uploaded.

To back up your pics/ capture you need to:

Upload captures from Xbox Live to OneDrive from your console

1. Press the Xbox button to open the guide, then go to Broadcast & capture.
   
2. Select Recent captures > See All.
   
3. Select the list view button on the right to display your captures in a list.
   
4. Select the check box next to the captures you want to upload.

2. Sign in to the app using your Microsoft account.
   
3. Select the Captures icon on the left menu panel.

5. Select the Download button to download the captures locally to your PC. These will be stored in the Videos folder on your C drive.

There is a couple of ways to transfer them to your PC.

1. Transfer them to the Onedrive on your Xbox one, then download them off there to edit on your PC.

2. Launch the Xbox Console Companion on Windows 10 PC. Select captures, and if they are already uploaded to Xbox Live, select Xbox Live, and download each clip to your computer, then you can use an editing suite of your choice.

What I do is capture my game with Xbox capture . Then Go to my captures on xbox app or xbox.com. Download them to my pc and edit them then put them on youtube . Easy way to by pass everything complicated.

You can not live stream directly from the console to youtube.

However if you have a capture card, you can download and OBS software to your pc and stream to YouTube that way.

Id look into a community forum on reddit, or watch some tutorial videos to learn how to use the capture card to stream.
