[edit]Is it really necessary to digress on the advantages to digital video in this article?

- Actually, Hi-Def refers to the amount of information recorded by the CCD chip (loosely equivalent to resolution), it is independent of frame rate. 24p refers to the capturing of full frames (rather than interlaced fields) using an algorithm to make the video appear as if it were recorded at 24 frames per second (standard film projection speed) as oposed to 30 frames per second(standard rate for video -- or 60 fields per second in interlace mode). Video tape still runs at 30fps . Capturing full frames rather than fields eliminates much of the jumpiness and the jagged edges that give Wedding videos their harshness. This is further enhanced by emulating the 24 frame rate of film. Both Panasonic's AG-DVX100a and Canon's XL2, the most popular entry level "indie" cameras, will record in 24p, but neither of them records in High-Def.
