I see in this first impression review they posted a photo of the tilting EVF that should make it work great for low angle shots.

It would also work great with the powerful Sony HVL-F60M Flash that also has LED lights for video mode.

Does YouTube stream 4K video?

Does YouTube stream 4K video?

Yes, here are screen captures off my 30" 2560x1600 monitor from the 4K youtube video of the 4K Sony FDR-AX100 :

I see. It looks really compressed. Which begs the question. Does 1080p at a much higher bit rate, more key frames with less compression look better than 4K that most likely has to be really crunched to be streamed over the internet.

Did you watch it in 2160p 4K mode on a 1600p or 4K display ?

On my computer monitor (2048x1600). But I think the resolution of the display does little to what YouTube will do transcoding what is uploaded. 1080p at a decent quality setting is taxing enough to stream on the internet. 4K has to be really compressed. I was getting interrupted viewing. And it would oscillate from sharp to that fuzzy compressed look.

I've only done a little video work and the few I made were recorded in 1080i, converted to an editing format and transcoded to 1080p for my home viewing and 720p for uploading to Vimeo. And the ones I made for home viewing have way better sound, better image quality (even when the same size) because I more bandwidth to set a higher bit rate, put in more key frames and sound quality for H.264 encoded video.
