“Regardless of how quickly we need to take Mitto to air, it works famously every time. And it looks spectacular. When
we covered the blizzards last winter, all of our user-generated content submissions and Skype camethrough Mitto.”
~ John Schilberg, VP of Technology, Grin Communications, KWTV, KOTV and KQCW
By Engineers, For Engineers
In 1989, a former television station engineer who loved designing
and building video equipment, decided to start a new company.
He relished the idea of taking an existing group of equipment
and adding a few special pieces in order to create an even more
elegant ensemble. So, he designed and built his rst product and
the company was born.
Focused On What You Need
As the company has grown, more former TV station engineers have
joined Ensemble Designs and this wealth of practical
experience fuels the company’s innovation. Everyone at the
company is focused on providing the very equipment you need
to complete your ensemble of video and audio gear. We oer
those special pieces that tie everything together so that when
combined, the whole ensemble is exactly what you need.
Notably Great Service for You
We listen to you – just tell us what you need and we’ll do our best
to build it. We are completely focused on you and the equipment
you need. Being privately held means we don’t have to worry
about a big board of directors or anything else that might take
attention away from real business. And, you can be sure that
when you call a real person will answer the phone. We love this
business and we’re here to stay.
Bricks and Mortar of Your Facility
The bricks and mortar of a facility include pieces like
up/downconverters, audio embedders, video converters,
protection switches, routers and SPGs for SD, HD and 3Gb/s .
That’s what we’re focused on, that’s all we do – we make proven
and reliable signal processing and infrastructure gear for
video facilities worldwide, for you.

Easy to Use
BrightEye Mitto is easy to use, both from the software interface and the front panel.
Screen selection, video format, timing and many of the other controls can be accessed with push
buttons from the Mitto front panel.
BrightEye Mac/PC software is included with each unit at no charge and provides an additional level of
control. BrightEye Mac/PC software runs overtop of any video, web site or software. The Selection Tool
shows up as a box around your selection and shows the portion of the video that will be output from
BrightEye Mitto. Simply use your mouse to click and drag over the specific portion of computer video
that you want to output. The perspective of seeing the whole screen gives you the ability to choose
exactly which portion of the video you want to output. It’s easy to output the entire screen or just
a selected portion. You can quickly and easily resize the selection window by clicking and dragging
with your mouse. Mitto’s video output automatically goes to pillarbox or letterbox as needed. Mitto
automatically maintains perfect aspect ratio.
From the software you have complete and intuitive control of timing, video format, and video level
adjustments. Presets enable you to store your favorite settings. You can easily time Mitto into a video
production switcher or router. Use BrightEye Mac/PC software to control a single BrightEye unit or any
number of units connected to a USB hub.

Exclusive Filtering and Scaling Technology
A superior quality scan converter, Mitto has the advantage of proprietary scaling technology and
exclusive multi-tap filtering. Even a small part of the computer screen, such as a YouTube video,
will be upconverted to full screen HD. The region selected for output determines if Mitto acts as an
upconverter or downconverter. The filters automatically adjust according to the conversion
being performed.
Bringing progressive images from the desktop into the interlaced world of video used to be a
compromise between sharp details versus interfield flicker. Mitto’s advanced filtering satisfies both of
these requirements. The result is that the output looks as good, or better, than the original and passes
the most stringent testing.
Digital and Analog Video
The intuitive front panel interface, or the included BrightEye Mac/PC software makes it easy to
choose the desired video output format, HD SDI or SD SDI. When the digital output is SD SDI, analog
composite video is also output on a separate BNC. The genlock reference input allows the video
output to be timed to house.
Audio Capabilities
The audio input accepts analog audio. Mitto Pro 2 supports embedded audio. The analog audio input
can be embedded into the SDI outputs which is useful for integration with video servers and routers.
Mitto Pro 2 will pass embedded audio that is present on the input.
Free Software Upgrades
Use BrightEye Mac/PC software to control a single BrightEye unit or any number of units connected to
a USB hub. The software is included with each unit at no charge.
BrightEye Mitto’s software is easily upgraded through the unit’s USB port. Software upgrades are
available at no charge for the life of the product and are conveniently downloadable from either of the
following links:

Every Mitto comes with a five-year warranty.

Functional Description
Video
The BrightEye Mitto Pro 2 scan converter accepts a DVI, VGA or HDMI input. The HDMI input requires
an adaptor. Output options are 1.5 Gb/s HD (high definition), SDI (standard definition), and Composite.
In a typical application, Mitto sits between the computer and the computer monitor. The computer
feeds the DVI-I input. The Mitto DVI-I Loop Out feeds the computer monitor. The maximum resolution
supported is 1920 x 1200 which is excellent for HD applications.
Mitto DVI/VGA Input and the DVI/VGA Loop Out use DVI-I (integrated) connectors which provide both
digital and analog connectivity. The larger group of pins are digital while the four pins on the right are
analog. Included with every Mitto are two 15-pin, VGA-to-DVI adapters for use in legacy installations.
SDI Out 1 and 2 output SD SDI or 1.5 Gb/s HD SDI video. The output includes only the portion of the
computer screen that you have selected with Mitto. Mitto upconverts or downconverts the signal
depending on how much of the computer video you select and the output standard you select.
The Composite Out BNC provides composite video out when SD is selected on the SDI outputs. If HD is
selected on the SDI outputs then the Composite Out BNC outputs black.
Audio
Audio is fed to Mitto Pro 2 either from the analog audio input or from audio coming in along with an
HDMI or DVI input.
Analog audio can be fed from the computer’s headphone out or line out into Mitto’s audio input. The
audio input is a 1/8 inch stereo mini-jack.
Mitto Pro 2 supports embedded audio and will pass embedded audio present on the input.
Embedding audio into the SDI outputs can be useful for integration with video servers and routers.
When Mitto’s internal test pattern generator is turned on (located in the Output Menu), color bars and
a 1.0 KHz tone will be on the SDI outputs.

Mitto Scan Conversion for Interviews
Use BrightEye Mitto Pro 2 with applications such as Skype, YouTube and Festoon to bring interviews
into your video production. You can have one or more video windows open on your computer.
Mitto converts the area you select to SD or HD SDI video for input into your video router or production
switcher.
Memory Registers
Use Mitto’s memory registers to store and recall specific selections. For example, if you have four video
interviews or windows up on your computer monitor, select window 1 and save that selection to
Mitto’s memory register 1. Window 2 to memory register 2, and so on. And you can pre-set a selection
that shows two video windows together, a two-shot. This is great for an interview segment.
Memory registers can be recalled from the BrightEye Mac/PC software. You could even use this as a
mini master control system and switch between eight different video sources from one computer.
