The Pik-A-Movie system was invented by Dr Leo
W. Wells and developed by Panacolor in which the German company Zeiss is the
major shareholder.
The system differs in that the cassette contains film and the equipment is
shown by optical rear projection to the viewer. Each viewer is delivered his
own set when he requests the service and consequently the system can be used
in any hotel. This is a considerable advantage when it is realised that only
a very small percentage of British Hotels contain a colour television in
each room.
The cassette used in the system contains 300ft of film and is sufficient for
two hours of programme. A single full length feature can be shown, or as
many as six different subjects may be programmed in a single cassette
measuring 61/2" x 7" x 4" (16,51 x 17,78 x 10,16cm). When
operating the machine, facilities are available for repeating sections of
the film or for studying a single frame.

The
Panacolor Pik-A-Movie 70mm cassette
with 70mm film. Picture by Thomas Hauerslev.
A special film process is adopted in producing the films for the cassette.
Twelve rows of super-8 sized pictures and twelve tracks of optical sound are
printed on a 70mm film as shown. It is, therefore, necessary for the
projector to be indexed from one row to another in order to completely show
the contents of the magazine. The film is transported through the projector
in a horizontal plane and the first row of pictures and sound are projected.
At the end of the first row an inaudible tone is superimposed onto the
soundtrack which causes the film projector mechanism to step-up one row and
reverse the direction of the film. This operation is repeated for the
remaining rows of the film: at the end of the twelfth row the film is
returned to a start position and the projector is automatically shut-off,
leaving the film completely rewound in the magazine. The film is transported
at 30 ft (9,144m) per minute and shown at a frame rate of 24 frames per
second. It is projected onto a rear projection type screen normally
measuring 71/4" x 10" (18,415 x 25,4cm) although this size can be
increased to 11" x 16" (27,94 x 40,64cm).
The operational controls are simple and in addition to the normal controls
for stop, start and volume, the viewer has the facilities for selecting any
row of the film and for reversing the direction of the film if required.
The system provides a solution for reducing the amount of film required to
show a full length movie and substantially reduces the processing cost for
producing duplicate prints. The cassette also provides protection against
damage normally encountered when the film is handled. The system is
obviously adaptable with the correct software to applications other than
hotel movies and then it would be entering the same market as EVR.

The Panacolor cartridge, incorporating 10 rows of a modified 8mm format on a
70mm film, uses a cartridge containing up to 350 ft (106,68m) of the 70mm
film with a film projection rate of 24 frames/s at 26 ft/min incorporating
photographic sound and a left-to-right and vise versa instead of up-and-down
transport. The projection unit has been introduced as a rear-screen unit
with a direct projection option and incorporates a rotating prism
synchronized by means of a sprocket. Each cartridge can contain up to 12
different short subjects, or single-concept films up to 10 minutes running
time, with random or successive selection.

12-Channel sound-Movie
Cassette plays for Two Hours
You never touch the film with the Panacolor sound-movie projector — just
drop the magazine on the spindle, close the cover, and press the Start
button. At the end of the movie, two hours later, the projector shuts off
automatically.
Don't like to sit through two-hour feature? The magazine can also hold six
20-minute features. You press a button that says "Row" to select the feature
you want. Other buttons let you control the sound volume and adjust the
treble and bass. A remote control offers forward, reverse, slow motion,
frame-at-a-time viewing or stop.
The system uses 70mm film, with 12 rows of super-8-size pictures on it. The
pictures are turned sideways to get them all on the film. About a quarter of
the film width is taken up by 12 double rows of squiggly lines. Those are
the optical sound tracks, printed on the film just like the sound track on
the film your local movie house uses.
The magazine can hold 300 feet of film. The film goes back and forth between
two reels: 10 minutes in one direction, 10 minutes back to the starting
line. It's projected in both directions. No rewinding is necessary.
The projector works as quietly as a tape recorder. That's because it uses
the same kind of capstan drive, instead of the usual clickety-click claw
that grabs the perforations and pulls the film past the lens. It's easier on
the film, too. The projector has its own built-in screen, but can also be
used with a standard movie screen.
Zeiss-Ikon-VoigtLander makes the projector for Panacolor, Inc., NYC. It's
intended for schools, business, and government. But you can have one, too,
for $595. Everett H. Ortner.
