| If
you are making your television commercials in the old
fashion 4 x 3 format, you could be in for a rude shock.
When commercial TV stations stop simitaneously broadcasting
analogue and digital it is reported that only 16 x 9 widescreen
format dubs will be accepted. This means that all of the
4 x 3 masters will need to be re-created at great
expense to the 16 x 9 format. Yet there is no
reason why any advertiser should face this prospect.
The
difference between 4 x 3 and 16 x 9

The
4 x 3 format is the traditional "square" format seen on
many television sets. The format was created because the
early TV tubes could only produce a square image, yet
human binocular viewing is better suited to the
widescreen format.

The 16 x 9 or widescreen format
is seen on plasma screens and digital widescreen
TV sets. (The black lines show where the 4 x
3 image ends) The only difference is the format of
the image. The 16 x 9 format uses more of the
image already captured on all film formats (35
mm and super 16 mm) and all digital video cameras have
a 16 x 9 setting at no extra cost to the production.
"But
not everyone has a widescreen television!"
True. But
it doesn't really matter. This 4 x 3 format on a widescreen
monitor has black down the sides where the image should
be.

While the 16 x 9 master below
has letterbox bands at the bottom and top just
like many feature films on DVD.

If
you don't like the black bands the station can fix it
If
you send a 16 x 9 master to the station, with instructions
to broadcast it in the 4 x 3 format they will provide
a "centre cut" on the analogue transmission that converts
the 16 x 9 to 4 x 3 at no cost to the advertiser.

The production company and the
agency just need to make sure the action and any
supers fall within the 4 x 3 action and title safe area
when creating the 16 x 9 master.

The
costs of not producing a 16 x 9 format
While
a 16 x 9 widescreen master can be simply and cheaply
converted into a 4 x 3, a 4 x 3 usually
needs to be regraded, edited and mastered into a 16 x
9, often costing tens of thousands of dollars. Within
a few years the stations will be broadcasting digital
only and the 4 x 3 masters currently broadcast will need
to be changed. There is no reason why all commericals
should not be mastered in the 16 x 9 format.
If you continue to use the old 4 x 3 format you could
be facing huge expenses later if you want to use the material
again.
