Shooting at 30 vs 24fps - Your preference

I haven't done much filming of skiing this year, but so far I've shot true 24fps and a bit of 60fps.

I like the way the 24 blurs the background, but while using a Glidecam, if the skier isn't being tracked directly there can be a bit of strobing.

(Also, does it look decent to shoot in 30 and export in 24?)

What is your preference and why?
 
I like to film in 30 because at least I can slow it down to 80% if I really need to for an effect or speed it up a bit but mostly if I'm gonna shoot slo-mo I just drop down to 720p 60
 
I would recommend against shooting 24fps for action stuff. 24fps is traditionally intended for narrative pieces, not action.

24fps doesn't blur the background, the motion blur is a function of your shutter speed. If your shutter is open for 1/120th of a second, it will be more blurry than if it's open for 1/250th of a second (because light over more time, and thus more motion, is allowed to enter the camera, creating a blur). You can have motion blur just fine shooting with 60fps.

It doesn't look good to shoot 60fps or 30fps and then export to 24fps. If you do that, you'll end up with skipping frames that make the resultant video slightly jerky/skippy. It's hard to notice unless you know what to look for, but it's a difference that means a lot to the right eye. To get rid of that, you can always interpret 30 and 60fps footage in a 24fps timeline, but this means that the 30fps footage will be fractionally slower, not realtime (80% speed for 30fps, 90% for 60fps)

I consistently shoot 1080p 60fps. I also always export to 30fps. Action looks better in a 30fps timeline anyway.

I did know this, just worded it incorrectly. Thanks for the input!
