You can reduce the sharpness which reduces the severity of the aliasing but it's still there, all the time. Take a look at this simple pull focus:

You wouldn't expect a shot like that to alias but it does due to the lack of a suitable optical low pass filter. Hybrid stills-video cameras will always be a compromise, make the AA filter work for video and the stills will be soft. Only this morning there was a great example of aliasing rearing it's ugly head when an extract of a web episodic was shown on the breakfast news. The clip looks fine on YouTube but when the full res original was broadcast it looked terrible twittering and flickering all over the place. I'm sure it looked fine in the edit suite, but the high frequency harmonics caused by aliasing can't always be seen. All I'm saying is "handle with care".
