Interlaced scanning was incorporated in the NTSC and PAL standards as a way of doubling the frame rate, without doubling the bandwidth required for analogue TV. Doubling the frame rate minimised flicker when viewing on an analogue glass (CRT) TV receiver. Also 50fps (PAL) and 60fps (NTSC) was adopted to to have the frame rate pretty much locked to the power mains frequency, to minimisehorizontal”hum bars” drifting down the picture on glass TVs.
Flat panel TVs store picture elements until replaced by the next frame so with LCD or Plasma screens, flicker, the real reason for interlaced scanning, is no longer a real problem. The great majority of the viewers of your wedding video will these days probably have a widescreen plasma or LCD TV,
Just as we all have transitioned from 4 x 3 to 16 x 9 in my view, so shouldwe move to 1080 or 720p. Unless you know that your audience will be viewing on older generation CRT receivers, there is no reason not to.
Over the last two or three years everything I have done has been in 24p and I have never had a problem,
