Help with frame rate

Hello All - a few months ago my 1080p footage shot with a 1/60 shutter speed has started having terrible lines throughout every shot. Example here:

I know I missing something basic. Appreciate any advice on settings you can give.

I'm not sure, you mean the flickering on the wall of the house above the black van at the beginning and on the "Top Shelf" writing on the white van later? Using 1/60 shutter speed you film with 30 fps (180 rule)?

Yes, that flickering on the lettering. I'm using a ND filter, aperture is down to about 5 and 30fps

I'm not seeing anything amiss. This is just 1080 (not higher rez) and this isn't a really a top notch camera or lens. It looks to me that the fine lines of the lettering simply isn't resolving at somewhat of a distance with those settings, which isn't unusual.

Do you have footage from the exact same hardware at the same settings with the same kind of lettering that does not do this, to compare to?

Thanks for the responses. I'll try bumping up the resolution and double-checking my shutter speed/frame rate. Cross my fingers.

After searching the internet, you can also try to set the sharpness to +1, this should switch off the drones auto noise reduction which can produce some funny effects. If that doesn't work try sharpness -1, that should minimize moire effects. I'm not sure which problem we see in the video. Good luck and keep us updated...

This is because 60 fps is too demanding for the camera so the software under-sample the image and apply sharpening afterwards. The under-sampling causes the flickering of fine lines. It will also cause moire at areas with tonal change at high spatial frequency. The following is a test I did earlier. Sorry, the M2P is good for still photos but not that great for video

Re +1 sharpness: that sure is counter intuitive. I would have thought that 0 sharpness setting would mean no "in drone" processing/adjustment. Does that apply to the other 2 settings, i.e., that color and contrast must be set at +1 to achieve no "in drone" processing/adjustment?
