First Yi 360 VR 5.7K video sample posted! Preorders now open at B&H!


The first 5.7K sample from the Yi 360 VR camera has been posted!  Check it out!  Also, B&H is now accepting preorders!

Here's the sample, posted by Sami Luo:



OBSERVATIONS

The detail is amazing for a 360 consumer camera, with noticeable improvement compared to 4K.  Even with YouTube's high compression, you can see the difference in the plate numbers and front grills of the cars here (click for full resolution).

In terms of optics, the sharpness appears excellent, with consistent sharpness almost throughout the field of view, except right at the stitch line.

There seems to be no chromatic aberration or purple fringing whatsoever.  See the lights through the windows of this building:


Stitching is not perfect.  For nearby objects, the stitching is quite noticeable.  You can only do so much about parallax stitching error when lenses are not that close to each other.

There were stitching errors even at farther distances (such as the windows of this building).

It almost seems as if this is purely template-based stitching, although I could be wrong about that.  At NAB, Yi representatives said that the Yi 360 VR has optical flow stitching, which should be able to stitch scenes like this, and they said the stitching would not be noticeable.  Perhaps this is a limitation of the preproduction software.

Update: A Yi representative said this is a preproduction camera using beta software.  The retail product will have better stitching.

The dynamic range is impressive.  You can see the detail in the shadow, such as the dark door of this building, while there is also at least some detail in the sky, which retained its color.


On a separate note, I also noticed that the video is not playing back smoothly at full 5K resolution.  I have a GTX 1060 6GB, a VR-ready graphics card, but my PC can't play the video smoothly (the same is true of any other 5K video on YouTube).  This is not too surprising, considering that each frame of this video has almost the same resolution as a 360 photo from the Ricoh Theta.  In any case, as PC hardware improves, more people will be able to view video of this resolution smoothly.

Notwithstanding these issues, this seems to be the most detailed 360 video sample I've seen for a consumer 360 camera, especially at this price range!

PREORDERS NOW OPEN AT B&H PHOTO
In addition, B&H is now accepting preorders!  I suggest using a credit card instead of Paypal so your order doesn't get charged until the order ships (with Paypal, they will charge right away).

Thank you very much to Suso Barral and Andrew Mines for bringing this video to my attention and thanks to Ed Lewis for sharing the info on B&H preorders!

  2. +360 Rumors.com We are getting closer for every week. This cam is fantastic regarding resolution, but I had to download the video to watch it flawlessly...couldn't do it over YouTube...I have ordered fiber internet and it's supposed to be installed after summer (september). I'm still waiting for a 8K cam under $1000 with a intelligent codec so I can stitch and edit the video in a "normal" laptop (4 core i7 16GB intel 4000/Nintendo 650 Gt...). But if that camera comes up - I'm ready to buy a faster laptop.

    1. hi Ulf. I think we will see 8k cameras for consumers in about 2 years. Yes I think stitching will become easier when the standard changes from equirectangular to cubic projection.

    3. Hi Ulf. Yes I thkn the Yi footage looks pretty good. Just to clarify though, the Yi 360 VR doesn't have stabilization. But yes it is impressive!

      Best regards,

  3. +Mic Ty Your right. No stabilization. He must have steady hands running with a selfiestick and the footage seems "stabilized"...and yesterday after a few glass of wine it looked more stable ;)

  4. i have a gtx 1070 and my pc struggles to play the 5k video. i think one thing to consider also is internet speed, as not every country has the internet speed to buffer 5k video some would even struggle with 4k video.
