Yup, that is the sort of horrible video I am talking about
(nothing personal, its the camera).
At the time I got my T3i I used an XT for stills and a HF S10 for video. I had a lot of issues with the XT and dust (it has no dust management system), so when the T3i came out I decided to upgrade. No regrets about that, not only did the T3i substantially solve the dust problem (essentially eliminated it actually), it also had far fewer issues with sensor light scattering (purple fringing). So the overall image quality was noticeably better.
When I got the camera I thought that I would be able to retire the HF S10, after all, the T3i had a bigger sensor and recorded at a higher bit rate, and we are led to believe that these are good things. Boy was I wrong!!! The video from the T3i is a lot less resolved than the S10, a lot of artifacts can be seen and any sort of camera motion results in jerking video. The only advantage the T3i had over the S10 was rapid motion by subject matter. The S10 records interlaced footage, so that sort of motion results in a stuttering effect on monitors (it is ok on TV sets). The only way to get anything approaching decent footage from the T3i was to lock it down on a tripod and ensure that the camera did not move at all.
Nowdays I use a G30 for video. It is much better camcorder than the S10, both in video quality and flexibility of use. I no longer see chromatic aberration, although sensor light scattering is still there (which, suspect, is an issue with any small sensor camera). I would never even think about using the T3i for video now. When I first got the G30 I did side by side comparisons with the S10 and the T3i, which reminded me how bad it was.
I have seen footage from the R10, and IMO it is better than the G30, and better than any other consumer/prosumer camcorder I am aware of. Footage from MLRAW-5D3 mostly (as far as I can tell) is locked down tripod stuff. It is not horrible, but neither is it all that impressive either. And I have doubts that it is much more capable of dealing with dynamic video any more than my T3i was. Neither camera was designed for video beyond being able to record it. When you see products like the R10 appear on the market, you know that old design philosophy is in the process of change!
