Re: 360 Re-Visited at 5.7K: The Yi 360

You are right (of course), now that link does not work and the Yi site does not offer it. As you can see from the video, there was firmware that added stabilization, and users used the link to get...

Odd.

I could buy @ $249 and start my own arbitrage business with UK customers.

Re: 360 Re-Visited at 5.7K: The Yi 360

Thanks for the report.

1. There is 3-axis gimbal available specifically for 360 cameras, that puts the motors below the camera and thus out of the way. Guru 360 is the name.

2. The latest Yi...

$199 Z Camera E1 vs Panasonic GH4: 4K Video Comparison

I bought the Z camera E1 for $199 - Black Friday Deal. It is now $249, it sold before for $599.

It is an m43 camera about the size of a GoPro, with 4K30p and DCI 4K at 24p. It has full manual...

Re: 360 Re-Visited at 5.7K: The Yi 360

Yes, I used the supplied software, as the camera will only carry out stitching in 4K, not 5.7K. Stitching in the software is very slow - on my i7 machine, 20 minutes of stitching for one minute of...

Still have not found an editor that will merge and render 5760 x 2880 videos at a high bitrate. So just clips for now.

Re: 360 Re-Visited at 5.7K: The Yi 360

It does have live HDMI out! And it's clean.

When the camera is set to 5.7K or 4K internally it outputs what my monitor reports as UHD and it shows the two raw unstitched globes. To have live...

Re: 360 Re-Visited at 5.7K: The Yi 360

Other than the long time it takes to stitch using optical flow in the free software (long!), it is straightforward. The stitching software will batch process all the clips and you can trim each clip...

360 Re-Visited at 5.7K: The Yi 360 VR

The latest consumer-grade 360 video resolution frontier is 5.7K. And the Yi 360 VR gives you that for $399. Resolution is critical for 360 viewing, since one sees just a part (slice) of the full...

Re: Report on the Yi 4K+

I switched to the Zhiyun Smooth Q gimbal. I think that other than putting the cam on a tripod and shooting long events, the best use for any action cam is on a gimbal - EIS quite visibly lowers video...

Re: Shooting documentaries with go pro etc

Thank you for the video and clip. What is "Native" white balance? And why did you use it?

Re: Report on the Yi 4K+

Can you cite some specifics? All the shots were from camera + gimbal. It is a fantasy that EIS can stabilize effectively when the camera is moving, and also does not severely impact resolution. For...

Re: Report on the Yi 4K+

256GB card; yes, an external battery can be used to power the camera, even without an internal battery. The card would give 4 hours of 4K 60P video at 135Mbps.

Re: Bought a Zhiyun Evolution gimbal, but.......

Thank you for the picture of your Zhiyun Smooth Q set-up, quite neat. With that arrangement, however, you lose the sound on the Yi 4K+, since the Yi's side mic is covered. You also cannot view the...
