Keep in mind that as of yet, LBRY does not transcode videos -- what you upload is exactly what your viewers will be watching. That allows higher quality than YouTube, but has several major drawbacks. First, you have to upload in a streaming-compatible format, like H.264 -- so near-lossless professional codecs like ProRes cannot be used. And more importantly, you have to be mindful of what kind of resolutions and bitrates your viewer's devices and Internet connections will be able to handle. So if you upload 4K 60fps video at a mega-high bitrate, it may look beautiful on your end, but a lot of your viewers won't be able to watch it -- and not everyone has unlimited data allowance on their service plan.
Also, the lbry.tv site is currently buggy in legacy Firefox and Firefox-based browsers like Pale Moon, and doesn't work at all in IE.
I've created a LBRY channel and uploaded a few test videos to it (

I'm also keeping an eye on FloatPlane (created by LinusTechTips) and StoryFire (created by McJuggerNuggets) to see how those platforms develop. For example, Boogie2988 already has 100,000+ subscribers on StoryFire -- that's impressive.
