Problem solved, from my editor:
In simplest terms, you're shooting 720 X 480 in standard resolution, The same
resolution as DVD. What matters, is the bandwidth, or data rate.
Most professional and prosumer camera's are writing to tape at 4mbs. Since
the signal is all digital, we're ingesting it, editing and then outputting at
the same rate, so you're not losing a thing when written to tape.
Now, in terms of DVD, our goal is make an exact digital copy of your source,
so all encoding is done at 5mbs, so there's a 1mbs stream of headroom
for spikes in light and dark. This ensures that what you shot, is what you
get back.
The best VOD companies are able to offer at this point, is 1mbs streaming
which they consider 'Hight Def'. Even as bandwidth increases and the VOD
companies begin streaming to televisions in the next couple of years, they'll
still be maxing out at what the cable and satellite companies are capable of,
which is around 2mbs on high frequency, high bandwidth channels. (Like HDNet)
It's why Blu-Ray's look better than HD Cable.
So anyway... your source DVD, even though it's in standard resolution, is
still encoded at 5mbs, which is way above what any of the VOD companies
are capable of reproducing, so they'll be downsizing it, no matter what
format you send it to them in.
They prefer DVD, because their systems are set up to ingest large volumes
of them. The studio's in the Valley are releasing 6 - 12 titles a month, so
they are just sending the VOD companies boxes of DVD's.
Given no other option, they'll accept DigiBeta and MiniDV, but that requires
that someone capture the footage and then encode it, and I suspect that they
may actually just burn a dvd and then put it through their system. The bottom
line, is with this option, you're looking at 60 - 90 days before your title goes
live on the network as opposed to the average of 30 days with most
of the companies.
I know this might be alot of geek talk, or tech stuff, so if there's any part
of it you don't understand, just let me know.
