Deinterlacing video…
HELP! I was reviewing AK’s tutorial on deinterlacing, and I was wondering… why deinterlace the video? What is the effect of deinterlaced video when played on a DVD player vs. non deinterlaced. I have heard both sides say “you should do it” and the other side say “there’s no reason to”. Every explanation I get is so over complicated and technical, they might as well be speaking another language.
Would you guys at VC be able to give me the “yeah” or “neah” on the deinterlacing thing and why, in terms that won’t make my brain hemorrhage?
Thanks-a-billion

Interlaced video is traditionally considered more suited to
sports (for example) where it’s important to maintain detail
during fast pans and tilts etc., whereas progressive/deinterlaced
video has that filmic blur more suited to drama, film, etc.Deinterlacing footage will reduce the sharpness of it by a
small percent — it’s something like a 15% loss of vertical
resolution.If you’ve shot some sports as interlaced and the footage is
only going to be used on television then there’s no need to
deinterlace it. If it was to be used cross-platform then
it would have to be deinterlaced because some web players
make interlaced footage look quite nasty.That said, a lot of broadcasters are using 720p as their default
HD sports format, and us too — we shoot super league rugby
every week in progressive (for web, DVD, television) and it
looks great; with the shutter speed cranked up too, it’s as
dramatic-looking as it’s going to get.Darren.
