Mark, the GoPro community understands the down conversion from 4k to 1080 for the extra details, we have been doing this with 2.7k from the previous models, whether the details or workflow is desirable is up to the individual user, their workflow time constraints and the type of footage they shoot.

Not the community I encountered on the web. I think the "community" is quite diverse. I agree with what you say otherwise, but the choice people make is conditional on their understanding of both the costs and the advantages.

The 4K in the new model has not been seen before - it is much better than in the older model. It is not clear that the 2.7k is. Also software and hardware has improved, so working with higher resolutions natively is much easier now. Finally, there is no need to downconvert. You can upload 4K to Vimeo or Youtube, for example, and most computers now will play 4K videos easily. And, 4K video viewed at lower resolutions looks much better than natively-shot "HD" (because it isn't HD).

During a break on a shoot I took a quick shot out the window to take this 4K shot

I'm one of the few (only?) people on the planet who actually care about the audio quality of the GoPro. (Everyone else says "Use an audio recorder as your primary recorder." Sorry, but I'm not going there.) Thus I am encouraged by what GoPro is saying about 'new and improved' audio quality on the 4 model. That's why the "hiss" concerns me.
That's good news about the curvature being lessened. I hope that's the case for all resolutions, not just 4K. I have the 3 and so I'm seeing fisheye big-time.

By the way, I called GoPro's tech support to give them a heads-up on the vignetting issue with the Hero 4 at 4K in superwide mode.
However, they're claiming the problem is with the user and NOT with the camera.
If anyone else has seen this, please call GoPro and give them your first-hand experience. (Mine is only based on the vimeo clip Mark posted as I don't own the Hero 4 yet.)

As the "user", I would like to know what I possibly could have done to produce the slight vignetting in the upper (not lower) corners, and ONLY in superwide mode? I shot the videos standing in back of the camera. The camera was on a tripod in the GoPro frame, which has the least bulk of any of the GoPro cases.

Mark,

Agree what would cause it from your setup? Mine comes tomorrow and I will do the same test since we are going to use it in that mode as part of our next shoot.

Sometimes if the camera is not positioned correctly within the housing the video will display a vignette usually on one side, this used to happen on earlier GoPro versions as the camera case or the Perspex locating lugs wore down after repeated use ( vibration on bikes etc), you could see the wear marks on the camera case.

This is the HERO 4 in its GoPro frame case. I do not see how it could induce vignetting, unless that GoPro lens cover does it (it comes with the frame), but that is unlikely since it is only the upper corners.

Re: GoPro Hero 4 Black 4K Videos
 
This is the email I got from the GoPro tech:

"Thank you for calling in today, and pointing me towards that video. I will look into it a little further, and let you know what I find out.

This is not a problem with the camera, but it could be the result of user error, or simply a particular problem with that particular camera itself.

Let me know if yo have other questions."

.................................................................................................... .........................................................

Barrage them with calls if you've seen it yourself, that's what I say.
Don't let them get away with the attitude "Hey, this is only a $500 camera, what do you expect?" Or, "Wait 'til Hero 5 comes out and we'll see if we can get it fixed by then."
Americans are addicted to mediocrity!

Do we know what modes received improved sharpness? 2.7K 48p was a little softer than 30p when I did some tests the other day. Same with 1080p80 and higher.

Otherwise, the new exposure and image controls on the 4 are fantastic. I get a good solid 55 minutes of 4K recording too! Wow!

How does the new Gopro 4 black handle interiors? What about lowish light? Compared to the previous black versions?
