Came across this image on reddit, thought some here might find it interesting. It's a visual explanation of the rolling shutter effect on the prop on all the RV videos that get posted around here.

via Gopro with 2 sunglass filters carefully taped on, Gopro mounted to bill of my baseball hat with double tape and alum strip with 2 bends to fit curve of bill (camera removed from orig case). Purchase of optional remote mic highly recommended. Only about $25. Can be put in earcup of headset.

Oh for sure - addressing it is trivial. I just thought this was a nice visual explanation.

DaleB,
I appreciate your attempt at education, but it left a lot to be desired. What makes you think that most of us have not already researched the web, and found simpleton answers. Only one spot (on the web) have I found real info. Example: A .6 filter will not remove the "banana", a .9 filter will remove it, but leave a wiggle, a 1.2 filter is better, but will not remove the wiggle, a 1.5 filter (.6 plus a .9 piggybacked filters) removes all the interference giving a perfect picture.
Depending on the amount of light coming in, that is, which can be vastly different depending on time of day. And the effective ISO rating of the sensor. And the aperture size. AND the speed of the rolling shutter electronics.
This isn't that hard of a problem...buy some filters and run some experiments.

So here are three filter and an additional piggyback setup, all advertised as "prop filters". Only one is truly adequate. So using the word 'sunlight filter' means nothing. (in the eyes of people who build airplanes that is).
So the question still exists: who has the best, for the price, filter system, whether it be store bought, or home made.
Please note that no where in the above thread is the camera and lens shown.
This forum is for how I made this part in shop today, not what I made in shop.
So once again, please please please show us how
