Alister, thank you for posting these clips and helping out!

My impressions where different depending upon how I watched the clip.

Inside of Quicktime, the motion is stuttery, but when I put it in Edius and played it out to my production monitor, all of the stuttering went away.

Bear in mind that especially the first clip where a lot of ground was being covered, even at 60 fps, the pan speed is going faster than the framerate can handle. This is even further displayed when the footage is slowed down.

I would say judder or skew is absent from these clips from what I see here.

At full speed, these issues would not even enter the mind.

Thanks again!

Looks like flashes might be the only cryptonite to deal with.

As always you have to be careful not to confuse stutter caused by playback problems with anything real in the clip. To my eyes all the clips from the airshow look as I would expect for 60P and 25P.

Strobes, flashes and some lightning can cause a problem with partially lit frames. When I shoot lightning I use the slowest shutter I can and the vast majority of my clips are fine. I did a wedding with lot's of flashes going off and there were quite a few half exposed frames, but the client didn't notice them when he watched the video.

I've experienced rolling shutter shooting lightning at 25fps, any solutions?

2 frame SLS and 25P works well for me with lightning.
