Here is how to upload Facebook videos to YouTube, so that every time you post on Facebook, the post gets automatically posted on YouTube (and any other social networks you select).
Using OneUp, you first connect your Facebook account and YouTube account (and any other social network you want to autopost to):

Then choose “Cross-posting” from the Create A Post dropdown options:

Then choose Facebook as the “Post from” account, and choose YouTube (and any other social network you want) as the “Post To” account:

That’s it! Now moving forward, whenever you post on Facebook, it will automatically post to your YouTube account with 2 hours of the original post.
Or you can optionally choose to add a delay so that it doesnt post to YouTube until after a few hours or days.
Here is a video showing how the autoposting process works in OneUp:
