| In studying the navigation parameters and structures of the DVD system set up at the NFB in Winnipeg, and in analyzing a collection of 18 NFB DVDs in particular, I have come to an understanding of the elementary functions of the remote controller; in short what we have is a DVD choice of north, south, east, west, and center. | |||
|
|||
| With these seemingly simple commands a multi-dimensional travel may take place; exploring a DVD’s content. | |||
| A
DVD is unlike a VCR, a Video or a Motion Picture Film, or a Vinyl Record
or a Cassette Audio Tape. Each of these preceding examples of media are of
but one dimension: a line. You can go forwards or you can go backwards. You
can see the movie forwards or see the movie backwards. You can hear the music
forwards or you can hear the music backwards. You can not hear the music or
see the movie sideways. The groves in a vinyl record go around and around
and around, but they are actually not groves; they are but one single grove,
one train track running from the outside edge of the record, running round
and round, in ever smaller spirals until they meet at the paper label, at
the end of the recording. . |

| Question: Speaking theoretically about a vinyl record; if you lift up the needle by hand and plunk it down by hand on another part of the vinyl record does that act not add another dimension, does that act not change the record from being a one dimensional media to a two dimensional media? |
|||
| Answer:.....NO. | |||
| Why not? |
|||
|
Because... the one dimensional time base media of a motion picture
film, a video, an audio tape recording or a vinyl record are all planned
as a single railroad track from beginning to end. Lifting the needle and
plunking it down only puts it ahead or behind on the track; earlier or later
on the single railroad line. The media remains one dimensional because
it was planned that way. |
|||
| Question: Could a vinyl record be made to be multidimensional with different planning. | |||
| Answer: Yes. When a vinyl record skips, repeating the same thing over and over again, what has happened is that the single railroad track has been broken part way through and has been reconnected to itself, ending in a repeating loop. The skip is a railroad track that is a long line (a spiral) ending in a small repetitive circle. | |||
If a vinyl record was designed as a series of tracks
that actually were circles, then the act of lifting the needle would indeed
make the experience, or travel, multi dimensional. You could choose to start
at the first circle or track, at the last circle or in the middle.
Question: What is a multidimensional navigational tool?
Answer: Look at a piano.
The multidimensional navigational tool of the piano is actually the
sheet music. Sheet music is the navigational tool that you would use to find
Beethoven’s ninth symphony. Sheet music notation is designed The challenge of making a multidimensional navigational tool for a DVD is that it must work and be used and be understood without instruction and without language for anyone, even an illiterate, a person from another culture and (for this project), it must work even for the blind, the deaf, the child and the illiterate. Fortunately, unlike the piano, the navigation system of a DVD requires only one finger and fortunately, unlike the piano with it’s 88 keys, the DVD only has 5. Not so bad. The DVD navigation system is five keys played in any order, but only one at a time with one finger. That’s too easy! Question: N E W S and C. Five keys, played one at a time, with one finger, is simpler than a telephone or TV remote control. Come on, what is this multidimensional stuff?
Answer: N E W S and C. If the DVD had just the commands NEWS it would be indeed only two dimensional. It would be a checkerboard, allowing one hop per turn in a direction NEWS North, East, West, or South, (with no diagonal moves).
DVD navigation is not just a checkerboard but is a stack of checkerboards. One hop North, or one hop East, or one hop West, or one hop South or one hop to a space on another checkerboard (another dimension). A
DVD is not something that you view. A DVD is something that you travel through.
(Without getting into science fiction), this ability to plan a travel, through
many dimensions, is what the planning of a DVD actually is. The planning of
the navigation, the navigation itself for the traveler (rather than viewer)
is an immersive part of the content. Each traveler will be presented with
many choices (five per click). Each traveler of a DVD may take a different
route. They may take a route of their own choice, or they may follow a route
that they know from remembering the navigation of other DVDs they have experienced
or they may take a route that they think they are instructed to follow by
the DVD itself, or from written material on the DVD case, or they may take
the route advised by a friend or they may just be trying to find some one
thing somewhere on the DVD just to show to someone (and they don’t want to
waist any time searching for it). You can of course throw the extra dimensions
away. A linear one dimensional DVD (video experience) will be the result.
There are many limited use DVDs that are in fact just one dimensional video
tapes; they go forward or they go backward, that's it. That’s NOT
what this project is about. This proposal, is to make one traditional animated
film. The film is about the 26 characters of our alphabet. The choices given to the travelers (bundled up in just the N E W S and C navigation) will in itself be a huge part of the content. Although the most entertaining "sit-down-and-watch-entertaining", part of the DVD, will remain the main animated film (that will be released to festivals and distribution on it's own), the DVD will be a place for many travels for hours of entertainment and education. The DVD will be designed for a single five minute encounter, or as a resource for students or as entertainment for English as a second language students or for illiterates (of all ages) , the blind and the deaf and for a academics. For the next stage of the project a film that will stand on it's own will be developed and story boarded in tandem with accompanying short animation tests that may eventually exist on the DVD. Admittedly what is being proposed is a lot of content, yet this material, in general can be animated and produced quickly. For example, the first ten weeks of investigation have produced thirteen presentable animated examples with sound. An estimate for the entire project to completion would be at the rate of one one minute of film completed per week, per animator. One animator, in one year could produce 50 minutes of finished digital animation for DVD. A brief explanation and anaylisis of the test animations done so far, can be found as links on the previous flash animation page including the initial purpose, method, and results for each experiment, followed by some conclusions based on the results. |
