In the black brick in the foreground, and in the roof beams of the dugout I noticed some faint vertical lines. When I went back and reviewed other footage on my computer I found that almost all of the underexposed areas or black areas showed the same vertical lines. Is this a compression issue, sensor issue, or hardware issue?

I'm just curious if anyone else has experienced this, or has any tips on how to avoid it.

Thanks for your input!
