4K Capture stops automatic upload?

Hi Jacob!

May I confirm if your clips and captures are saved on your internal storage or external storage?

Let's make sure that automatic upload is enabled.
Press the Xbox button to open the guide, and then go to Profile & system > Settings > Preferences > Capture & share > Automatically upload.

To upload a capture that wasn’t uploaded automatically, select the capture, and then select Upload.

There are a lot of people with exactly the same problem 4K Capture stops
automatically after 23-24sec and that file is corrupted,
this problem started after the last update (15.5).

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

Have you changed consoles (eg upgraded to an Xbox One X) or your game capture settings to 4K SDR or HDR? If you selected 4K captures then you now need to manually upload them to Xbox Live. Only 1080p or 720p clips are automatically uploaded to Xbox Live
providing you still have space remaining.

If you want to check if you are near your storage limit on Xbox Live then open Recent Captures and select Show All. There will be a warning if you are near to the limit (not 100% if it displays at 90 or 95%). If you see the warning then select some of the
older clips you no longer want to keep and delete them to free up space on Xbox Live again.

Good luck!

While it will show in 4k via the console, when it is downloaded, it can only show what is supported by the device it is being ahown on, most phones do not suppoet 4k hdr. Aswell as it is waved to a cloud network, so whem shared it will auto adjust its resolution
to make its its packet smaller. As of right now sadly xbox doesnt seem to support the 4k hdr share system.
