Greenish and pink patterns

[Jacobus Serpenti]

Hello everybody,

Could someone tell me what these patterns are and, most of all, how to get rid of them by means of filtering ?

For those interested, the lake is located at Bled in Slovenia, the theater is in Taormina, Sicily.

Thanks in advance

Those are called Newton's Rings. They appear when the sun (or bright light source) refracts off a reflective surface at 22.5 degrees from horizontal.
In other words, a rainbow.
This is usually avoided by coatings on the lenses of cameras, and/or polarization filtering (sunglasses for example).
You may be able to avoid them in the future by appling a lens hood to the camera, or putting on a polarizing filter.
To remove them from your current videos/stills, is going to take some work, manually, in a good editor.
