Hello all. I'd like to know how to capture video at 60 fps, instead of 30 fps. It's locked at 30 fps no matter what format (AVI, Mpeg2) I change it to in the advanced settings. And yes, I recorded the video at 60i. ...The same thing applies to Windows Movie Maker... Any help would be hugely appreciated.

60i is 30fps.

You would need a camera capable of shooting at 60fps. This rate is effectively a slow motion rate (i.e. the frame rate is twice the normal speed) and you thus require a camera with variable frame rate capability. 60i is interlaced footage, and two fields are combined to give 1 frame - hence 60i = 30fps

Ok. When adding the slow-mo effect to the video footage, the quality shows to be ugly. Is this caused by video at 30 fps? I figured it wouldn't be ugly at 60 fps.

60i is recording more information than 30p maybe not by itself but when you de-interlace the 60i footage correctly using a 3rd party application, you can get 60p.  If you don't plan to do this, just film in 30p.
