Why won't my youtube video upload after 14 hours?

I uploaded a 10 minute video to youtube 14 hours ago and it shows up on my channel when I'm signed in, but when I log out and try to find it it's not there.
I've heard it takes a while for the video to fully upload or something, but I don't think it should be taking this long.
However, keep in mind that I filmed it on a Kindle Fire and uploaded it on youtube mobile after saving it as an .mp4 file. Would this have any effect?
