Help me identify the banding issue?

[saf34]

Hi all, just a quick one.  Could anyone help me identify the banding issue I'm having with my MLV file in the highlights?  I'm almost certain it's been discussed, but I haven't managed to find an image example that helps me identify it.

My workflow:

Canon 5d mk iii > mlv_dump to DNGs > After Effects

The mlv_dump vertical stripes fix seems to be working in mlv_dump fine.  And these stripes are not just vertical.

Image (zoomed) attached.

Thanks in advance!

Without knowing the post-process of this image, there is no way to tell. How is it in MLV app?

Post a cut mlv file.

Alternatively, is there a Grid placed over the light?

Thanks for answering Kharak.  I was being a total dumbass: it only appears when being played back in a resized VLC window...  It's been a long week!
