NEX-7, Shutter speed at 1080p/60 FPS for smooth video

El Matadurr:

I did make a lot of experiments with 60 FPS and found out tthat for my taste fast shutter speeds (for example 1/500) produces a series of crisp frames, but have a very choppy look when played back in slow motion. A slower shutter speed such as 1/60 on the other hand produces a series of slightly blurred frames, when paying back sports scene in slow motion.
1/125 with 60FPS is what I found not choppy and not blurred.
