Video quality problem, video vibrates

[ Edited ]

Hi,

After some time of recording on 2K 60 video started to vibrate. By vibrate, I mean that some parts of screen are moved, like here. These shifts occure many times per second on different places of the screen, and looks like some parts of screen vibrate. Screenshot below for reference. Sometimes only some parts of the screen are shifted like here, sometimes all screen "vibrates".

Re: Video quality problem, video vibrates

Make sure you are using one of the recommended SD cards as per GoPro's instructions.  Also try performing a manual update of your GoPro to the latest firmware (1.8).  

 

It looks like the camera had issues keeping up with writing the data during recording, this could be due to a buffer problem with the EIS or too slow an SD card.

I have to highlight that during the same trip, same enviroment at the begining of recording all was completly fine. But second half of trip was tragic. So, if there is a problem with firmware of bad memory card, this should not be a problem all the time, from the start?

Maybe this was overheating, but if yes then why camera still recorded for a next 15min untill batery was dead?

 

Looking for opinions, maybe someone had similar bad experience?

 

What is the EIS?

Re: Video quality problem, video vibrates

For all you know, your firmware could be corrupted and it only comes into play after 30 minutes of video has been recorded, fact is you're not going to know unitl you try updating your firmware and eliminating it as a possible cause.

 

I'm guessing it may have been related to the EIS due to the blocking observable.  It's like the buffer didn't pass the information to the finished file quick enough (Electronic image stabilization).

 

Same with a corrupt or bad SD card.  You could have perfectly fine sections on the card and some bad sections, so some of your recording is fine, some of it just didn't work.  Until you try another SD card or peforming a scan, you can't say for sure.  A slow card will gradually overheat, once it reaches a certain temperature it will either cause corruption, the camera to shut down, or for the card to run slower until it cools down again.  This could also be why the start of your video is ok and the end is ok, but you have a large section that's corrupt.
