So at around 30 seconds there's a lot of video flickering that's going on when I'm bringing the P3 STD to a stop.  Is this something a lot of people have experienced?  I was using a ND8 filter at the time to compensate for the very bright day.  It's also happening on my DJI spark when I go through areas where the light changes rapidly.  I'm using manual exposure settings as well.

I'm assuming it has something to do with the propellers.

I manually go in and adjust my shutter speed and ISO.  As for White Balance, I just pick one of the canned WB modes.  On this day I picked "Sunny" seeing how there were no clouds in the sky and it was very bright out.  I've seen people set the (kelvin) in YouTube videos before though, but I don't personally go in and set a value.

Taking a look at it just a few minutes ago, I think I could get it down fairly easy.  I've got a pretty good photography background so I understand WB as a whole.  I'll have to play with it next time to see if that makes a difference.

I'm definitely not a pro photographer.  I'll have to try to see with my next flight.  I want to get this down before I head to LA for Christmas so I can get some really good B-Roll of the beach.

Looks like glare to me, as though the filter is not quite flush and is at angle therefore picking up the props, there is some jello at the end too, ever so slight, see it on the housesTry again without filters to rule that out?

Hmmm, didn't even think of that.  These are the ones that just slip right over the camera and not the screw on type.  I'll have to do another flight to see if that works.

The major problem with the video clip is that you are facing into the sun. There is lens flare, the green spot in the middle of the shot, and prop shadow when you are in the air. Try facing the other direction.

Also, being winter, the trees are bare and this plays havoc with the MPEG encoding process, there is too much fine detail for the encoding process to handle.

Definitely noticed the lens flare in the video.  Thanks for the input, will have to take all of these things into mind for my next flight.
