Re: Sony Posts First PXW-X70 4K Video
That was impressive; especially with the low bit-rate that is YouTube. I was only able to watch in 1440p. Insane amout of crisp detail.

Re: Sony Posts First PXW-X70 4K Video
With youtube settings set to 4K, and surely without a 4k monitor, I got a lot moire in this video. Also, a fair number of artifacts.

Re: Sony Posts First PXW-X70 4K Video
Very interesting, when I drop down to 720 the moire disappears... Could be my system, could be my screen.

Re: Sony Posts First PXW-X70 4K Video
I too watched this on my tablet at 1440p. No moire, no aliasing to be found. IMO at least at this level of downscaled resolution, there's not much more you can ask for in terms of detail considering the cost and the portability of the equipment involved. There's some weird white balance in a number of limestone hill shots but that's probably just me. It should be easily corrected to taste in post, however.

Re: Sony Posts First PXW-X70 4K Video
I am getting it in the rigging of the sailboats, on top of the videographer's camera, in the sign above the cheese, lots of places, when at higher resolutions.

Re: Sony Posts First PXW-X70 4K Video
I just watched again at several resolutions and cannot see any moire. The only artifacts are slow frame rate motion that I am not too fond of but not sure if that is the source or Youtube. Downside for me is I expect the X70 4K will be only 24P and 30P and if its like its big brother the PXW-Z100 it will be 8bit 4:2:0 not 60P which is what I want in 4K. They could of course do 60P 8bit 4:2:0 at 150Mbps which is what my FDR-AX1 does. Then the X70 would be really interesting to me.
I watched on my mail/browsing PC which is an i7 3770K with 16G RAM, WIN7 64bit with Nvidia GTX560 GPU and Dell 24" monitor ( 1920x1200 ). Ron Evans |

Re: Sony Posts First PXW-X70 4K Video
So, am I right in assuming this was shot with the 60Mbps 4K codec the X70 will get, not the 100Mbps 4K codec the AX100 has just got?
Looked pretty good to me - watching on a Full HD 24-inch Dell Ultrasharp 2408WFP - and then I watched it again on a higher res (but still sub 4K) 27-inch Dell Ultrasharp U2713H monitor - driven by my old and new Mac Pros respectively.

Re: Sony Posts First PXW-X70 4K Video
There's not a heck of a lot of motion in there... I mean some, sure, but not a ton.
The most dynamic looking shot was the one where the guy quickly runs the camera over the table full of pots (1:01). But then we don't actually get to see the shot he captured! What's up with that? |

Re: Sony Posts First PXW-X70 4K Video
The Mbps indicator may indicate that they may add the AX100's 100mbps in a later upgrade, albeit, there is no way we're able to get 60p out of this camera or correct it's skew issue.

Re: Sony Posts First PXW-X70 4K Video
You can download a 1080p version of PXW-X70 4K Beauty Image 1080p @ 3500kbps here:
http://goo.gl/y3oiZY I also have the 3840 x 2160 UHD version at 15000kbps and it does look very, very clean but I can't afford to chew up too much bandwidth on my account by uploading it as it's the best part of half a GB. Interested in anyone's thoughts! Chris Young CYV Productions Sydney |
