I shot about 80GB of 4K video with the Sony A7S II on my trip. I’m not sure what to do with the footage, which I’d like to make available, but it’s huge; I can’t host it directly and provide the bandwidth.
In the past, YouTube has mangled even my 1080p video, so I’m not happy there since I want to show the native 30P/100M 4K quality from the Sony A7S II. Or any other future 4K camera.
Vimeo won’t stream 4K video (download only). And it’s not clear what is done to the material; I want it presented as-shot in 30P/100M, not recompressed and mangled, since that would defeat the purpose of video evaluation. I may have to resort to Amazon S3 and downloads (not streaming). Even that is problematic since 4K is so large and it incurs additional costs, so I may have to charge for this sort of thing. Pondering what to do here, but it is not a short-term decision to be made quickly or lightly.
The EVF in the Sony A7S II is inadequate for 4K recording: I cannot tell if I’m in ideal focus or not since the EVF is only 2.4MP and 4K is 8.2MP! Total disconnect here between medium and viewing the medium. And note well that small errors are obvious in 4K when viewed on a 4K TV: even professional films show focusing errors! And those guys are experts with the full 'rig'.
I shot some videos showing the various focus modes of the A7S II; all modes have their issues; IMO none are up to the task in this 'rev'.
Lexar SDXC in A7S II
On my recent trip I used two cards to record 4K video on the Sony A7S II. Both worked flawlessly. First, I filled the Lexar 64GB 2000X card to capacity, then continued using the Lexar 256GB 1000X card.
One usability issue with the A7S II: it stopped recording when the 64GB card filled. Maybe it beeped or something, but I talked on for another eight minutes or so (a selfie how-to video). I had been presenting to a camera that had stopped recording. There ought to be a loud braying-squirrel sound indicating “hey the card is full”. I’m sure a camera operator would notice immediately, but for a selfie/demo video this behavior sucks.
Given the storage demands, my pick for the Sony A7S II would be the 2-pack of Lexar 256GB 2000X SDXC.
Curiously, the Lexar 2000X did not work in the Sony A7R II. UPDATE: the Lexar 64GB 2000X card works fine with the Sony A7R II using the latest Sony firmware.
