Video file
02.1 Video setup simple screen
A simple screen is defined as
a setup with all cabinets in one big rectangular shaped screen
.
The resolution of the video file that is played back by the media device is different from the actual
resolution of the screen. When exporting the video,
use standard HD (1920 x 1080 pixels) or 4K
(3840 x 2160 pixels) video resolution
. The footage that is shown on the screen (LED tile video) is
positioned in the top left corner within this video. The remaining part of this video should stay black.
Depending on the media player, other resolutions can be used. Below you can
find the instructions how to prepare your video using a BrightSign media player.
Also other workflows are possible, but this workflow makes sure you won’t face
any scaling issues later on.
The resolution of the LED tile video should be exactly the same as the resolution (amount of
pixels) of the screen.
This is called
‘pixel to pixel’
and means that every pixel in the video represents
a pixel in the screen.
To calculate the resolution of the screen, first you need to
count the amount of cabinets in your screen.
To calculate the resolution width, multiply the amount of horizontal cabinets in your screen with the
amount of horizontal pixels in one cabinet (Hi-LED 55 2.8 = 176 pixels; Hi-LED 55 2.5 = 192 pixels). To
calculate the resolution height,
multiply the amount of vertical cabinets in your screen with the amount
of vertical pixels in one cabinet
(2.8 = 176 pixels; 2.5 = 192 pixels).
