TL-1: INTERVALOMETER (DV-BANK ACCESSORY)

DATAVIDEO'S NEW TOOL WITH VIRTUALLY UNLIMITED APPLICATIONS

Datavideo's Intervalometer TL-1 is an easy to use, microprocessor based
DV Bank accessory that will open up new worlds of creative, scientific,
technical and business opportunities for you. Now you can have unlimited
real time control of your production technology and use 'time' more
efficiently and imaginatively.



What's an Intervalometer? Simply put, a video intervalometer allows the
user to determine the number of video frames the DV Bank records and
how often it records them; it enables the creation of time-lapse video
images. Thus, very slow activities (such as clouds moving across the sky)
appear to be speeded up.

Datavideo's Intervalometer and DV Bank allow you to shoot single frame
images, produce activated or general-purpose interface (GPI) triggered
segments, animations and time-lapse videography.

The Intervalometer allows the director/producer to "compress elapsed time"
and gives you nearly unlimited creative potential because the look, style
and overall effect of the final video can be fine-tuned:
- Choose how often an image is recorded.
- Select the number of frames recorded at each time interval.

INTERVALOMETER MANAGES DV BANK RECORDING IN 4 WAYS

1. Programmed interval time/duration.

2. Instant one-frame recording: just press the SINGLE FRAME record button.

3. Remote activation using a general purpose interface (GPI)-trigger switch,
motion or movement sensors, limit or proximity switches, or

4. With appropriate software and interface, recording can be computer
actuated. The Intervalometer and DV Bank can also be used to animate
"still" images, creating "moving" images like in traditional cartoons. Again,
the director/producer determines the recording time interval and the number
of frames to be recorded. When the video is replayed at normal speed
(30 fps) the process creates a continuous image that appears to move.
The Intervalometer is exceptionally useful in creating unique opening titles,
revealing data on a chart or for creating an easy to follow instruction guide
for a complex process.

Datavideo's Intervalometer opens up new worlds of creative and technical
opportunities enabling you to pitch new clients and to get involved in new,
exciting industries by offering unique, never-before realized creative and
visual approaches to tough business, scientific and technical problems that
have previously defied solution. Because the DV Bank records in DV you can
easily edit sequences, title or replace frames with popular software like
Adobe Premiere, Final Cut Pro, Express DV, etc.

12V DC OPERATION

How to determine how much battery capacity is needed to operate the
DV Bank and Intervalometer from a 12 VDC source?

This is a conservative example:
The Intervalometer draws 5 Watts
The DV Bank draws 45 Watts
Let's assume that it is 60 watts instead of the actual 50
The Datavideo DC/DC Converter is about 85% efficient - let's assume that it
is 75% efficient
So we'll make a worst case assumption that the DV Bank and Intervalo-
meter, powered through the DC/DC Converter of 80 Watts at 12 Volts.

Ohm's Law is Amps = Watts / Volts
80/12 = .71 Amps to operate the DV Bank & Intervalometer at 12V

Note: The load from the camera and ways to recharge the battery should
also be considered.

TYPICAL APPLICATIONS

Medical & Healthcare
Datavideo's new Intervalometer is perfectly suited for countless medical
and health care uses. Whether operating in the lab, university, or in a
hospital, clinical setting or an operating room, the Intervalometer provides
the doctor, researcher, practitioner, educator and technician the flexibility
to record, visualize, analyze and present medical procedures, data, new
protocols and outcomes clearly, concisely and creatively.

Scientific & Technical
And, if your subject matter is more high tech than anatomical, the
Intervalometer can be programmed to capture just about any visible
chemical reaction, mechanical process, scientific or natural phenomenon.
You can even use it to record paint peeling off the side of an old barn.
You could videotape a special spring rose blossoming for a perfume
company. Or, you could record a scientific experiment determining the
pH of a substance in relation to various temperatures. With Datavideo's
Intervalometer and an external GPI-trigger the Intervalometer you can
easily take a shot whenever the pH reached your target level, at a specific
temperature .The Intervalometer lets you master your subject without being
a dependent on pre-programmed time intervals.

Security, Business & Training
All organizations, be they commercial, governmental, civic, educational or
social have special needs for video security, documentation, presentation,
research and risk assessment that Datavideo's Intervalometer can meet.
Whether it's surveillance of a hotel parking lot, market research, pedestrian
traffic flow or the courtroom presentation of an expert witness, the
Intervalometer is flexible enough to be programmed to capture just the
data needed, at any time interval throughout the day or night. Exceptional
videos can be produced easily and quickly for an elementary school
"assembly," for risk analysis experts' review, or for cadets at the fire
academy.

Creative & Imaginative
The Intervalometer can also be used to condense existing video to playback
in less time. For instance, if you re-record a 60-minute videotape at: one
frame per second, you'll end up with a 2 minute long tape two frames per
second, you'll end up with a 4 minute long tape three frames per second,
you'll end up with a 6 minute long tapeWith Datavideo's Intervalometer,
you can combine different animations and techniques, recording time
intervals, numbers of frames, and existing video together into unique
sequences. You can even use it to "pencil test" your animation or graphic
build. You can easily move the camera as you animate, or between
segments, put it on a turntable, zoom in or out, add filters for special
effects, all without changing the subject or lighting. The Intervalometer
makes it easy for you to master time and it encourages you to realize the
full, imaginative potential of your creative self and your technical expertise.
