Re: Hero 7 Black - Hypersmooth failure. Super glitchy warped footage

Hi Jay,

 

Yes I think my point is more it shouldn't be a recommended SD card for this camera or the Hero 6 Black. Otherwise people will try to use it for 4k60fps and get sturrering when it can't keep up.

 

Or there should maybe be seperate column in the SD recommendations saying "4k60fps", then only have certain cards listed, such as the Pro or Plus versions of the Sandisk Extreme card.

Re: Hero 7 Black - Hypersmooth failure. Super glitchy warped footage

When folks assert that this card is "not fast enough" I think they're getting their MBytes/s and Mbits/s confused.

The highest bitrate the Hero7 records at is about 78Mbits/s  which is only 9.78MBytes/sec.

Any UHS class 1 (U1) card is supposed to support a *minimum* sequential write speed of 10Mbytes/sec or 80Mbit/sec.

A UHS class 3 (U3) card must support  30Mbytes or 240Mbit/s.   

The OP's card is a U3, as is most of the cards that people report having problems with.   No other devices but the Hero6/7 have these kinds of issues with U3 cards.   

 

That said, I doubt very much that the weird stuttering behavior in the OP's video has anything to do with card speed.

It continues stuttering even when the camera stops moving.   It looks like a fundamental failure of the EIS algorithm and it has just freaked out.

Re: Hero 7 Black - Hypersmooth failure. Super glitchy warped footage

I've got the same issue, filming at 2.7k 60FPS Hypersmooth

Footage starts off fine then starts to glitch. Its bright sunshine and 14 degrees C

I'm using a 64Gb Class 10 Sandisk Card, it isn't on the recommended list, but has worked for about 4 hours of smooth footage with no issues. About half an hour into yesterdays ride it started to glitch, initially a weird rectangle on the left side of the image, then the whole image started to glitch. I've wondered if this was a weird issue causedby low battery issue as I changed to my spare battery after this. I didn't see the issue with my spare battery for the rest of the day.  The battery that initially came with the camera also had issues not charging reliably to 100% and sticking at 98%

 I've uploaded to Google drive -

Glitching footage that then stabilises near the end.

If any one could point me to a UK supplier of a recomended 64Gb card I guess I could try that but I'm unconvinced its SD card related. Searching the part codes just seems to bring up American links / stores.

To add to the above I'm on firmware 1.51 which I manually updated the day I got the camera.

Yep, exactly the same issue. Come on GoPro where’s the solution?!

My battery was probably pretty low, as it was the end of the day.

Re: Hero 7 Black - Hypersmooth failure. Super glitchy warped footage

I've uploaded the first bit that I noticed had a weird glitch, it shows a rectangle on the left side of the screen. Seems to show the issue a lot better when you download the original file from google drive.

Re: Hero 7 Black - Hypersmooth failure. Super glitchy warped footage

Seems this is happening to a few other people as well, all with the same symptoms and resolution settings.

I've had no response to my ticket I raised with Go Pro Support.

Has anyone else got any answers with this >?
