Try emailing it to Facebook. This will take a while as well, but it might be more successful.
Also remember that if you have uploaded a video and it's removed within a minute, there's copyright infringement, meaning you probably recorded copyrighted background music. Facebook does NOT warn you of this. If you keep uploading it because you wonder why it didn't appear, your uploading permissions will be blocked and in their rules they threaten to maybe 'also block your account', which didn't happen to me when I found this out.
