How do I upload a clip from Onedrive to Xbox Live?

Can you send a video clip as an xbox live message to frends after its' uploaded to onedrive? If so, how?

There is a way to upload them all in bulk to your OneDrive. Depending on how much OneDrive storage you have would depend on how many you upload at the same time.

On the Xbox console, goto captures, then select manage, then the select all option, then select Upload to OneDrive. As I said, though, adjust that if you don't have a lot of OneDrive storage. Once they have uploaded, move them from OneDrive to your PC, and then do the process again for the next batch of clips you want to download.

I would like to see a OneDrive upload queue, they never appear in the Upload queue from the drop down list.

So after posting this I added some brand new clips to upload to OneDrive and they appeared in the queue. However before I posted I added 7 clips that previously didn't upload in a batch and within a minute they appeared on OneDrive. My internet isn't fast
enough for that. So it seems like the clips must fail but remain cached on OneDrive and when you re-upload them they continue from that point.

So I noticed another strange thing which makes me think I pinpointed the behavior. I had the OneDrive web page open at the folder it uploads to. A clip had uploaded to this folder and another was in progress. When the second one uploaded I noticed that the
first clip was replaced with the second. It appears they both had the same file name 21-09-2018_10-28-28_PM.mp4 and it's my suspicion that when they are queued to upload to OneDrive some of the clips must be queued at the same second and hence have the same
filename. I'm going to play with adding each clip to the queue one by one instead of selecting them all and uploading them.

Would also be great if you could specify OneDrive as the default upload location for clips, instead of Xbox Live.

Unfortunately captures are automatically deleted from the Xbox network after 90 days now. You could try opening the Captures app and selecting "On this Xbox console" from the drop-down list at the upper-left, as clips are not automatically deleted from the console itself after 90 days, although they do get deleted from there over time as you capture new clips and screenshots. It's worth checking though.

What I do is set the console to automatically upload my captures to both the Xbox network and OneDrive, as they are not automatically deleted from OneDrive and it makes it easy to save any ones that I want to keep on my PC. Unfortunately, you can't share clips uploaded to OneDrive on your profile or via an Xbox message, which is why I upload to both.

But yeah, if your missing clips are not on the console itself and you only uploaded them to the Xbox network, they are gone for good I'm afraid.

Are you saving the clips to Onedrive first, then uploading from there?
