Dissolving Or Fading Between Sources; Cutting Between Sources; Wiping Between Sources - Datavideo HS-550 Manual

Dissolving or Fading between sources

Select the Main Video Source by pressing an appropriate channel button. The button for the channel you have
selected should be illuminated Red and you should immediately see that source on the Program monitor. Now
select the Sub Source that you want to dissolve to, illuminated Yellow. The default transition is a fade/dissolve
(this button will already be lit when you first turn on the switcher). Move the T-Bar to the opposite position and
watch the fade happen between the sources on the Program monitor.

Cutting between sources

The HS-550 can do 3 kinds of transitions: fade (already
covered in the previous section), cut and wipes. The cut is a
simple switch from one input source to another. Not flashy, nor
fancy, but it gets the job done. In fact, if you watch a film or
video, paying attention to the transitions, you will see that the
cut is the most often used transition.
You select a video source by pressing one of the buttons 1, 2, 3, 4 or BG (Background colour). For example, if
you press button 4 on the Sub Source row your selection will be confirmed by the same button being illuminated.
The chosen Sub Source button is illuminated Yellow. The chosen Main Source button is illuminated Red. When a
Main Source button is pressed the main output of the mixer immediately shows or cuts to that video source on the
Program monitor. This means that you can perform simple cuts between video sources just by pressing different
buttons on the Main Source row.
Pressing a Sub Source button may not cause an immediate change to the HS-550's main output or Program
monitor. The selected Sub Source button (illuminated Yellow) only identifies which video input source will be next
shown when using the T-Bar.

Wiping between sources

Select the transition wipe button that you wish to use. There are in total 11 different Wipe styles and the
corresponding transition icon will be displayed in the bottom left corner of the Preview monitor when you press it.
The last button on the bottom row (see above picture) with a checker board marking is the Dissolve/Fade button.
At this point you could also press the Preview button, to see a sample of the selected transition on the
Left hand HS-550 Preview monitor. This Preview is for confirmation only and is not sent to the main
outputs or the Program monitor. Once this Preview is finished the monitor will return to the Quad view.
In a wipe transition, the change from one source to another happens along a predefined edge. It is like one
source image is being pulled back or pushed on top of another source image. Depending on the button selected
the starting point and direction of the wipe is changed.
But a picture is worth a thousand words, so... try this ...
Select a main source and sub source, select a Wipe, or Fade from the buttons above, press the "Preview" button
and see what it would like. Then, perform the actual transition manually by moving the T-bar up and down.
See the next page for a list of wipe transitions and variations.
