Glass reflection flicker issue

[Ogrus]

This was filmed 1080 25P on hmc40
These is some strange "flickering" on the white curves on the bottle
and then on the large one on the right near the neck area of the bottle
I noticed the same effect on the edge of a glass of wine, a flicker effect
What is this due to?
Fluorescent lightning?
Wrong Iris?


Thanks!

Doesn't look like fluorescent banding to me... was your knee on "auto"?

[Ogrus]

Yes, knee was on auto.
