K-S2 Video Rolling Shutter?

I am down to deciding between the K-S2 and the Nikon D5500. Both solid cameras, and both have the pros and cons. But one point that I can't seem to find a lot of input on is the video quality of the K-S2.

I have watched dozens of Youtube videos, and only a fraction of them show real world video samples. I have noticed what appears to be a slight 'jello effect' of the rolling shutter that used to plague camera phones. I wouldn't expect it to be on a camera of this level.

Can anyone confirm or deny this? And have samples to back it up? While shooting video would never be my first priority with a still camera, situations do arise, especially with the kids. Constantly moving around chasing kids is something that rolling shutter effects would definitely be a deal killer.

Yes, there is a slight rolling shutter effect. The K-S2's video mode is the same as what's in earlier Pentax models, so refer to these pages for samples/findings:

Rolling shutter affects all CMOS sensors.
Are you aware that there is no fast AF during video? So this wouldn't be a good choice for DSLR video.
The Jello you may have seen in samples online is more likely due to the digital shake reduction (MovieSR) that Pentax uses in video mode.
