As a video creator, I've had trouble using Dtube as well. Some times it doesn't allow uploads for whatever reason. Viuly is another blockchain option I'm using that works fairly easy. Bitchute is one I'm looking at, but I prefer the blockchain based platforms.
DTube needs some work, maybe the IPFS is also a weak link at this point. Entirely new systems of communication are being created right now, it will take time and require patience. It's happening though.
