After shooting, editing and authoring (the
process of segmenting the production into chapters and wiring it all
together with custom menus) most of our work is delivered to our
clients on DVD media.
While the majority of our projects are limited to the distribution
of no more than a few disks (in the case of weddings, video
transfers and music videos) there are certain events we cover where
the distribution is significantly greater. These include recitals
and competitions.It is primarily for
those who receive these DVD's that this section has been published.
Additionally, we hope that any others who might benefit from this
knowledge be blessed as well, including associates in our field.
Thanks to the vast amount of information readily available on the
net, as well as industry insiders who gave of their time and
expertise, we were able to assemble what we offer here. It is our
pleasure to help pass it on.
Concerning the issue of disk compatibility
among home players, we've naturally found that the phenomenon is
exponentially amplified in situations where dozens of people are
attempting to play back media on dozens of different pieces of
equipment. Further, we realize that most folks don't have a clear
enough understanding of the limitations of the media and are
dumbfounded as to why we gave them a 'bad' disk. What oftentimes
seems like a bad disk is usually just a compatibility issue with the
player being used. What normally (and most understandably) happens
is this causes people to question our integrity or the quality of
our service, regardless of how dazzling a production we create.
Unfortunately neither of the above assumptions
are correct. We are firmly committed to excellence, care deeply
about the entire performance, and try our best to showcase it in its
best possible light. Coming to the table with 30 years of
professional entertainment experience, it's only natural that we get
nearly as swept up in it as you.
Now we realize that everyone is so accustomed to renting movies and
hardly ever experiencing difficulties, unless of course the disc is
obviously scratched. But why shouldn't one of ours play just as
easily, each and every time? The answer is simple, yet somewhat
intricate, so please bear with us.
The following is a fairly comprehensive analysis of recordable media
and disc compatibility. We hope that this information, along with
the assurance that the steps we take to achieve the highest
compatibility with the discs we distribute, will help alleviate any
frustration you may feel when you hit play on your little star's
shining moment and instead of viewing the cinematic event you were
expecting you're treated to something more resembling Mr. Toad's
Wild Ride.
First Things First
Standalone (home) DVD players are not by default programmed to
recognize or properly play recordable media (DVD-R's). It doesn't
matter what make or model, or how new or old your equipment is,
manufacturers up to this point have simply provided this ability
basically to be nice. Home players at this point in time are
produced to play DVD-ROM's (feature films). No matter how futuristic
a picture they paint, the computer and entertainment industries have
not yet fully merged -- on our end at least. There's no obligation
yet for them to acquiesce.
With this in mind it's pretty incredible that we only receive a
relatively few reports of incompatible (burned) disks on home
players. But that still doesn't sit right with us. We're doing all
we can to tip the scale in our favor and allow you to pop your disk
in any tray with the least amount of concern.
Suffice it to say that our productions should be viewable on any PC.
So before calling with a suspected bad disc, if you've either not
been able to play it on a standalone player or are experiencing
intermittent errors/skips, etc., we implore you to find a computer
to try it on first and see if it'll play on that. This will
undoubtedly reveal if the disk is truly 'bad' or simply a matter of
incompatibility with the player(s) you're trying to view it on.
A word to the wise regarding computers and DVD's. Do yourself a
great favor and use DVD player software (WinDVD, PowerDVD, etc.) to
view the production on your PC. Do not allow Windows to let it
autorun and have Media Player take over. You'll be navigating blind
if you do. There'll be no button highlights and if you use the
forward and back buttons it will frustrate you to no end. You'll not
know where you are and there's no 'menu' or 'title' button (like on
a remote control) to escape with. You'll be forced to skip through
the entire production just to return to the main menu. Not a
pleasant thing.
So faced with the compatibility issue of home players (the obvious
preference for most to view their disc, we realize) and the current
state of the technology, what's a filmmaker to do? What can be done
to guarantee that every order placed will play perfectly on every
type of player imaginable?
The answer to that, of course, is a resounding "nothing." So the
next question is "what can be done to increase compatibility to its
maximum level?"
That's where our research began and here's
what we found.
Dupe, dupe, dupe. It's a whirl...
At first, we thought "well let's just send
them out for professional duplication. That ought to solve
everything."
"Not so, grasshopper..."
You see, there's Duplication, and then there's Replication.
Replicated disks are stamped (or pressed) from a glass master. These
are known as 'retail ready' disks, and are what you buy when you
pick up that copy of Shrek 3 at WalMart for the kids this Christmas.
Works all the time, every time.
Problem is it's not at all feasible for our humble productions
(yours or ours). Replication is normally only done for orders
of 300 or more (and trust us, we receive a very small fraction of
that for any given event) and the cost is astronomical. We'd
actually be paying you to produce it for you. Not that you
wouldn't approve, we're sure...
So that leaves duplication as the only viable option.
Duplication is the process of burning the image onto the disk. The
minimum quantity for professional high speed duplication is much
lower than replication, yet believe it or not still about 25% more
than we normally receive orders for, and costs 3-4 times as much as
we can do in-house. And they do the very same thing we do in-studio,
only in larger batches at a time. We were told this by one of the
nation's largest duplication houses. So this option wouldn't help
much either with regard to increasing playback compatibility.
So given the reality that duplication is the only feasible option,
and that the technology to perform this process is basically the
same in-house or out, the question then boils down to "how can we
'bullet-proof' our disks as much as possible?"
We've discovered that with proper diligence (and a real clever trick
we learned) it's possible to significantly increase the odds in our
collective favor.
Here's the 5-point production plan we adhere to:
| 1.
Quality media |
We use the best consumer
grade disks available. There are pitfalls to finding and
choosing which are best, as you can read here, but we're
careful not to purchase any obviously questionable media. |
| 2. A slow
burn |
To help reduce errors,
it's suggested that a slower speed burn helps. We burn at
the very minimum possible speed to increase disc
reliability. |
| 3. Data
verification |
A verification of the
data on the disk after it's burned adds to its chances of
success in terms of missing data, resulting in intermittent
playback. |
| 4.
Speed/Failure test |
All disks contain some
number of errors. The first thing that professional
duplicators normally do is run your master through some sort
of fail test. We run each disc through this utility to test
its error rate after burning. There's a negligible area and
anything below that is discarded. |
| 5.
Bitsetting |
Probably the most
significant boost in increasing disc compatibility on home
players is a little-known technique called Bitsetting.
The "Book Type" is a field of four bits at the start of
every DVD that indicates what the physical format of the
disc is. Many devices will use this book type field to
determine how the disc should be treated. One common cause
of compatibility problems is when a device does not
recognize the book type of the disc that has been loaded.
When the book type field (bitsetting) is changed to DVD-ROM
then DVD players are fooled and will think the user has put
in a DVD-ROM disc instead of a DVD+R disc and will read it
accordingly. This results in an increased chance that the
player is able to read the disc. |
In closing, we recognize that DVD's are awesome things, and what
they allow us to do and share is equally incredible. But much like
us human types they're not nearly as perfect as we'd like them to be
at times. It troubles us that, much like the subjects we film, we
pour our heart and soul into creating as magnificent and polished a
production as we can, only to receive feedback that some of the
discs weren't viewable by those who purchased them.
We remain committed to providing the highest quality production (and
product) we can. And we thank you for your understanding and support
of our creative endeavor.
