3. Video projection
Video projection allows us to change the time of day and create an ambience
without changing the set.
Long throw projector
 Long throw projects are used for long distances. It has
several inputs which are 2 VGA inputs (Video Graphics
Array) which goes from the PC to the
projector, HD, DVD, USB, sound input, phono input and
a video recorder input. Although this projector can go
long it could be pixelated. In shows they are normally
used in front of the stage to project an image on the
screen at the back. However the issue with this is that
actors on stage may get in the way. So a way to get
around this is place the projector behind the stage and
then flip the image so the actors aren’t in the way. Also a
long throw projector is discrete because it can be used
from long distances, this is an advantage when using it
in a performance.

without changing the set.
Short throw projector
 The short throw projector has all the same inputs
as a long throw projector but instead of using a lens
to project the image, the image is projected on to a
mirror which then reflects the image. In comparison
to a long throw projector the short throw project can
be used in confined spaces for example backstage
where space is limited. The image is inverted so
when the audience look at it the image appears the
right way But it isn’t as discrete as a long throw
projector which prevents it from being used in the
rig whilst a long throw projector can be used in the
rig and behind the audience.

Qlab
Matrox is used in cooperation with Qlab and 1 Matrox box has 3 outputs. Matrox can
either play 3 images on each projector or stretch 1 image across 3 projectors. It is used
for playing videos during performances and it is used for a individual projection or used
to project one large projection. I would use a matrox when I wanted a video of a scene to
play through the show, e.g the sunrise/sunset , I would play a video on Qlab of a video
which has filmed the sun through the day and stretch the video using 3 projectors.

6. Qlab
 Qlab is an industry standard piece of software (only on a
mac). It is cueing software, not media creation. It allows you
to playback music, sound fx, soundscapes and also it can
send a go to a lighting desk. You can play things on cue, and
fade up and fade down tracks. Therefore you can create
show lists.
