Questions about Videography
By Babylon Video Productions
Are
there different formats of DVD’s?
Yes,
there are three tape formats that are known as DV
(digital video) formats: MiniDV, DVCAM (Sony), and
DVCPRO (Panasonic).
Which
format is better for my wedding video?
A
DVCAM format is best for your wedding video as it
has a faster tape speed and a wider track pitch.
This means that the data is recorded over a larger
area, which reduces dropouts (dropouts are defects
in the picture caused by the physical loss of the
particles used on the tape to record). This makes
DVCAM a much sturdier and dependable format. You
can also play this format anywhere and on
different types of viewing equipment.
Will
my wedding DVD be compatible in a HDTV in the
future?
As the
copy of your wedding video, after editing, may not
be in DVCAM format you can request to have a copy
in the DVCAM format. This will ensure that you can
later have it transferred to a compatible format
for newer TV’s and equipment.
If
I want my video on my computer how much space will
it take?
MiniDV, DVCAM (Sony), and DVCPRO (Panasonic) all
utilize the same compression method called DV25
(which is sometimes just referred to as DV
compression). The data rate is 25 mbps. This is
why it’s called DV25. This makes makes it easy to
predict how much space an amount of video will
take up on a hard drive. Here are some useful
figures (sizes are approximate):
1 Second = 3.5 MB
1 Minute = 215 MB
4 Minutes, 40 Seconds = 1 GB
1 Hour = 13 GB
How
long can I expect my video to last?
Because
both video and audio information are recorded
magnetically, a video will last indefinitely with
no loss of quality if it is properly stored.
Do
I have to hire a separate wedding photographer?
No,
some companies offer both wedding photography and
videography. A wedding can be a stressful event to
plan so why not book 2 vendors in 1! If you find a
company that you like and trust that offers both
photography and video then why waste your time and
money booking a second vendor?
