Upload problems

I am trying to synch some .MP4 videos from my desktop to the cloud. I have a very strong Internet connection (312 Mbps down / 12 Mbps up, measured just now) and the files are roughly 500-600 MB each. I am running LR CC 4.2 and I have been trying for a week to synch these files, and they are not moving. I paid for a storage upgrade in my CC account specifically so I could back up ALL of my photos and videos to the cloud, but this is ridiculous. I also have a SmugMug account and everything uploads there without issue. 

Is there any way to not synch specific files? I have these files backed up to both Google Drive and my SmugMug, (WAY BETTER than Adobe) so if they're not backed up to Adobe it won't be the worst thing. But I want the videos to be kept in the same folder as the photos for catalog purposes.
