Shooting at 1/30th and below *will* reduce resolution and

increase stair-stepping effects (at least in Sony cameras...) since

one field is dropped. The image is unacceptable except for

emergency use in very low light, to reduce gain effects. If you

must throw away the advantages of interlacing in video for

standard interlaced TVs (a mystery to me why anyone would

want to, except for video displayed ONLY on computer

monitors...), then the 30p mode would be the way to go.

"30p" refers only to the display mode, not the shutter speed,

BTW...
