HERO6 Black - I just bought this cam. Why is there no Linear view for 4K? Disappointed!!

Just unboxed and went through all the options and settings. Much to my surprise and disappointment there is no linear mode in 4K! This is a serious limitation.

Ouch that really bytes maybe the restrictions due to their latest chip?

It's probably related to how the linear mode works by cropping the sensor down to a narrower field of view. If it did capture 4k in linear it would have to be something like 1080p upscaled or maybe 2.7k upscaled. The only way to not crop the sensor is to have a removable lens and unfortunately the only way to do that is tear apart your gopro

we've never had Linear mode in 4k, even the 5 Black only had it upto 2.7k

Re: HERO6 Black - I just bought this cam. Why is there no Linear view for 4K? Disappointed!!

You do have linear view, you just don't understand how the camera works. 4K is using the entire sensor. When you modify the fov to Linear, you have to crop what the sensor has picked up. By doing so, the camera has to drop to the next highest resolution. To have Linear on 4K you would either need a higher resolution than 4K or would need interpolated video, which isn't true 4K and looks bad. BTW, most other action cams that say they have 4K use this method and aren't truly giving you 4K. They used to do this with 1080 by upscaling 720p so they could say their camera had HD. Just like then, these little tricks the cheaper camera makers do don't work well and don't look good.

So what you just said  sounded like you got interpolation  Software enhanced.

[ Edited ]

sorry if that was confusing. You get interpolation with other 4K cameras. If GoPro were to put linear at the 4K, it would either need to do this or it would need a higher resolution available on the camera. Film in 2.7 linear if you want and just upscale in your editor and you would have the same result. Or, if you have an editor like Adobe Premiere Pro, you can just use Optics compensation to flatten the video picture.

Actually 2.7 linear upscaled in an editor looks better than interpolated 4K video.
