Re: 480P - Anyone know what this is?
I would like to see the post facilities make a stand for 1080i mastering of film for
DTV delivery. For those that want 1080i delivery the job is easily done and the gear
is already (well almost) here. For those that really want 720p format conversion
from the 1080i makes more sense than scrambling around and spending tons of money on
720 gear that simply duplicates the work just done in 1080i.
Considering all telecines scan the film internally at 1080p 24fps and interlace on
the output, it is a fairly straight forward task to de-interlace the video back to
1080p 24 and spatial filter the 1920x 1080p to 1280 x 720p for broadcast to those
who want it. Oversampling is always better! This moves us closer to eventually
creating the single delivery master for all DTV formats and it simply makes sense to
do so. Panasonic make the conversion box and soon will have a 1080p 24 fps version
of the D5 compressed HDTV recorder.
By the way, every receiver manufacturer that has announced a HDTV product line has
said that they will NOT display 720p! They will convert to 480p or 1080i because the
720 scan frequency is simply to high and costly to drive bigger monitors. So why are
broadcasters insisting on a format that will (at least in the short term) never be
directly displayed?? And why should post houses go broke creating it when there is
an easier anwser??
Other than that, I have no opinion!!!
