Ever see this? Glitch in GH4 file.

Jpeg from GH4 RW2 file

I shot a 700 image time lapse, at least two of the images suffered this fate. The two glitched shots were a few hundred apart from each other. Time lapse interval was 1 frame per second fwiw. The line is in nearly the exact same position in the file give of take 10 pixels. The line is in the raw file. Is it a card write error? Sensor error/ failure?

If anyone has insight on the issue, I'm all ears.

Thanks

I've seen that on both my GH3 and GH4. Incredibly rare though, and I couldn't tell you what conditions they were under when it happened.

It's almost as if a single line wasn't written to the file.

Cheers,
Paul

Thanks for responding ;-). I'm starting to wonder if it's the sensor failing to keep up. That said, it was shot at a slow frame rate which I wouldn't think would be a problem. I scratch my head.

Last time I saw something like that it was because a laser beam had passed though the lens but but the damage to the sensor was permanent.  Don't take your camera into a disco with laser beams sweeping around.
