Possible to shoot in 4k/60 fps in linear mode with hypersmooth?

[ New ]

I currently have the GoPro Hero Black 7, while I like it, I have the same freezing issues others have, where it wont turn on/off at the worse time when I really need it. I also dont like the barrel distortion (fish eye view) from shooting in wide mode so I always shoot in linear mode. With the Hero Black 7, the max resolution in linear mode is 2.7k. So in making the decision to see if it is worth upgrading to the Hero Black 8, I ask the question:

 

Will I be able to shoot in 4k/60fps in linear mode with hypersmooth enabled? I also see on the 8 there are different levels of hypersmooth. which ones, if any, will work in 4k/60fps linear mode?

 

Ive seen mention that the 7 batteries arent up to snuff for the 8, is that true?

 

Also, just out of curiousity, when taking photos with the 8, are they still only 4:3 or is there a 16:9 option?

hi,

no.

 

4K 60fps Linear ---Hypersmooth "off"  (off - on - high - boost).

4K 60fps Wide  --- Hypersmooth "on"  (off - on - high - boost).

4K 30fps Linear --- Hypersmooth "boost" (off - on - high - boost).

4K 30fps Wide --- Hypersmooth "boost" (off - on - high - boost).

4K 30fps Superview --- Hypersmooth "on" (off - on - high - boost).

 

 

as per battery... hero7's fit in hero8 ...specs are the same.

 

but hero8 keep saying " for max peak performances use hero8 batteries".

 

 

 

hope this helps,

robert

strange as manual says:

 

Heads Up: HyperSmooth is unavailable when recording 4K60 video with
the Linear digital lens. It will use standard video stabilization in its place.

Dang, is that someone that might be enabled with a future firmware update?

 

I guess Im not understanding why its such a big deal for GoPro to include all the availability for linear mode as for wide.

Well, unavailable and off will end up in the same thing - no hypersmooth

puzzled me as well... didn't see this coming...

...ok....and this phrase means what?

It will use standard video stabilization in its place. -- copied from Hero7?...for sure as Hero7 has normal and hypersmooth.

OK, the gopro has a 12 megapixel sensor - roughly 4000 pixels wide. by 3000 pixels high

 

UHD 4k has a resolution of 3840 by 2160.  Thats about 8 megapixels.  For wide this is jest cropped out of the image and it just copies across the area it needs.  Narrow does the same this except that it crops out a smaller area.

 

Linear Digital lens applies a pincushion distortion to the image captured from the sensor to straighten out the fisheye distortion created by the lens.  To do this it has to calculate where every pixel in the original  image will end up in the undistorted image and make sure that there are no blank spaces where pixels haven't been mapped to, interpolationg them from the surrounding pixels.  It has to do this for each pixel in the frame - every 8 million of them - for every frame in the video so that would be 480,000,000 pixels to recalculate and remap for each second of the video.

 

On top of that any level of stabilisation tracks movement of the camera, calculated how the image would have changed and cuts out the crop from a section of the image sothat it looks as if the camera has never moved.  It needs to detect the movement of the camera up, down, left, right, tilting, panning, rotating, calculate where this puts the required section of the image needed.  This is a calculation intensive operation that requires processor and memory.

 

The gopro has a state of the art image processor - but it is still not all that powerful in computational terms and there's a limit on how much it can do per cycle.  The amount of memory in a Gopro is also a finite resource, IIRC its 2GB.

 

So with limits on its processor and a finite amount of memory remapping 480 million pixels a second whilst performing realtime tracking of  the camera in 3d space and repositioning the "frame" 6o times a second might be a tad too much for the camera at the moment.

 

 

 

 

 

Might have to wait for 2 firmware upgrades.

I saw at least one reviewer say he received confirmation from GoPro that Hypersmooth WILL be available in that mode after an upcoming firmware update in November. Whether they stick to that time estimate remains to be seen. It's still early in November.

That is encouraging if that is true.. maybe I will wait to see if the next firmware update does the trick before "upgrading" to the 8

This was his exact text. He does a lot of very thorough reviews both on his own website and on Youtube. He is dcrainmaker  dot  com.

 

From the comment section:

 

"I got confirmation from GoPro last night that they’ll be rolling out a firmware update to the Hero 8 Black in November (exact date TBD) that will enable 4K/60 in Linear mode *with* HyperSmooth 2.0. It will not be Boost, but HyperSmooth."

that is great news! Now for my noob question: what is the difference between Hypersmooth (like what is on the 7), Hypersmooth 2.0, and Hypersmooth Boost?

this:  Smiley Very Happy

one of the best comparison I have seen ...

pay attention as well as the increase crop hypersmooth boost use....

 

enjoy!

That is an interesting comparison. It really looks like the High and Boost modes are just the same thing with more cropping, is that the case?

The additional crop allows for more Stabilization. Because High is so good, it really takes special circumstances to see a difference. When the Media Mod and Flip screen come out, Boost will get the most use when vlogging as it brings the user a little closer to screen and helps smooth steps and the background horizon.

....in addition to what @danielr15  said... look at the horizon... "boost" keep it better...

 

boost "feels" when radical short movement with high amplitude happen
