2 Pro Video has moving horizontal & vertical "bands" on buildings - Why?

[zlek131]

I am seeing bands on skyline glass buildings which move horizontal on some while vertical on other buildings. Any idea what may be going on? Never noticed this before. Filmed with Mavic Pro 2 in d-log and then edited in Premiere Pro. Thank you in advance for any feedback.

I couldn't see what you were asking about but was it this?

Moiré effect in displays: a tutorial

The tutorial describes essential features of moiré patterns, as well as the circumstances, when the moiré patterns appear and how to estimate their characteristics (parameters) such as the orientation and period. The moiré effect is described in two domains, the image space (spatial domain) and...

Couldn't see any problems in your video. Is it in the origional AC recording or the edited video?
I used to have problems filming weddings in Progressive, but changed back to interlaced and no problems.
Always with verticle stripes on shirts or corrugated iron fences when panning.
The AC is all Progressive recording.

Had another look at your video in HD and 480, all looks perfect in HD and just some slight bands in 480 for a few seconds.
Otherwise a great video.

I didn't see anything on that clip either? Are you talking onscreen view? If so turn off the over exposure warning (Zebra stripes) in your camera settings.

I see only artifacts introduced by the transitions.

I could see some red bands on one building towards the right side of the cluster of taller buildings. My guess is that it was refraction of light from a largely glass fascia on that building. Just a guess.

Here is a close up of the bands I am talking about. You need to watch the video in 4K/full screen to see them.

I can see the bands in both, original and edited video. They are more visible in the edited version. Posted a close up pic of the bands in a earlier reply above.

Could this be moiré?

You must have really great eyes or it is on your system.

I had mine cranked up and did not see it but some flashing on the right building.

Could see it on 4k video, but had to look close at it.
Never seen it before.
The bands in your photo look different than the ones I can see.

 

[Barbara]

I think it's probably artifacts due to the distortion caused by the masking technology used by the reptillians to camoflage their spaceships. Or not! ;o)

Yes, that's the bands I am talking about.

 

[TommyP]

Yes, that's the bands I am talking about.

I found similar bands in some of my videos. Check out the garage roof on the right and the shed at the bottom right corner. This is from my Mini1.
I stripped the Mini down and found the faults were caused by bad earthing and poor plugs onto the boards.
Also the cable from the camera passing by the gimble motors was causing a different colour problem.
My latests recordings don't have any problems or colour distortions after the repairs.
Maybe completely different with the Pro 2 but worth a look.

That's Moire Effect, explained in post #2

 

[Rich QR]

Yes, Moiré, which happens because the buildings have a regular repeating pattern to their window frames, which almost but not quite aligns with the pattern of pixels in your camera.
