Aliasing. I don’t know if it’s maybe something to do with shutter speed. It used to happen a lot with GoPros mounted on drones.

Yes probably that any ideas ?

Thanks @ash2020 will take note :+1:

Modern cameras have anti aliasing filters fitted in front of sensor to combat this.
Downside is you get a softer image. I suspect there is nothing as far as this type of filtering goes on drones.
Nikon released a D70 many moons ago. It was their first consumer digital SLR. no anti aliasing thing on that. The images were pin sharp. It got some criticism for this so the later stuff had filters fitted. Interestingly they later released a pro camera body with a version without the filter.
Adjusting your angle if possible can eleviate it.
Personally I’d rather have no filter and pin sharp.

The MP at 60fps is terrible for it :slightly_frowning_face:

To be honest had an ND 4 filter on, actual images fir client are spot on it’s just the video

Nd filters won’t compensate. It’s correct name is Moire. I couldn’t remover earlier long day lol.
Don’t know the exact science but it’s to do with parts of an image with fine details that matches the CCD array on the sensor. A phenomenon of digital cameras.

Hi @milkmanchris I was 30 FPS

What are you viewing your footage back on? I’ve edited stuff that’s come from the US that has been shot 29.97fps and that can often lead to that type of ailiasing when we view it in a project that is set 25fps. So it could be the monitor you’re using?
Converting to 25fps may help?

Someone had this kind of issue when watching on a TV with image sharpening on, or set strangely.
If viewing on a TV - check that setting.

Could be that you need to make sure that output and source framing is exact!
Being a photographer you can in Adobe Premier Pro use Gaussian Blur… it does work
