Hi,

I've noticed some glitches in my 4k120 recodings. Kind of dead pixel row, bright dots.
They're also noticable in other's videos on youtube but much less often.

Do you know the cause? Can we expect this to be fixed in future firmware release?

Here's sample video. Added some freeze frames when it happens.


Firmware: v01.01.05.10
Recorded internally

Cheers!

Impressive video but I can't see the problem... maybe I'm blind or stupid...

It took me a while to spot what you mean. I had to pause the video at the point where you freeze frame, to see it. It is annoying, but I doubt you'd spot it when the video is running?

It's very difficult to spot. After several tries I managed to stop the video at the same point as he freezes frame (0m27sec) and you can just spot a thin red horizontal line 2/3 way down the RHS of screen. Faint, but it's there.

It is definitely harder to spot after aggressive compression, on small screens or at lower resolution. When editing it's super annoying and I see every bad frame

Picture in higher res, bright horizontal line at the bottom.

I see what you mean. Have DJI offered an explanation?  Possibly not.

I have the same color lines in the video, when record at 120fps.

I replace mi action 2 for another Action 2 on amazon, and the new dont have this lines in 120fps.

Is a defective unit.
Be carefull with this, is a DJI quality problem, not software fixable.

Uh oh...
This is not good...

More newly uploaded videos on yt have this glitch.
I don't think I'll be such lucky with a new unit and I'll simply return my A2.

Thanks for the feedback @BEN_M16 !

I shot a little in 4K120 and didn’t see that issue with mine. Hopefully this is not a wide spread issue and can be handled easily by DJI or vendor.

Looks like a bug indeed.
