Picture-In-Picture And Downstream Key - Datavideo SE-4000 Instruction Manual

The Key 3 layer (chroma key or luma key) does not occupy the whole screen and is shown in
front of the Background video, Key 1 and Key 2 layers when enabled.
The Key 4 layer (chroma key or luma key) does not occupy the whole screen and is shown in
front of the Background video, Key 1, Key 2 and Key 3 layers when enabled.
In some setups the Key image can be hidden behind other key images. This is not a fault.
Change the position or size of the Key image if required.
The DSK 1 layer can occupy the whole screen. If set up incorrectly this layer can stop the video
layers behind it from being seen properly. Re-adjust your DSK 1 settings or switch off the DSK1
function on the SE-4000 to restore the video behind it.
The DSK 2 layer can occupy the whole screen. If set up incorrectly this layer can stop the video
layers behind it from being seen properly. Re-adjust your DSK 2 settings or switch off the DSK2
function on the SE-4000 to restore the video behind it.
The logo layer is the uppermost layer. If the standard logo (still) is chosen, the maximum logo
size will be restricted to 480x1080. If the animated logo (dynamic) is chosen, the logo will be
confined within 480x270.
Note: Where possible prepare and position the upper video layer elements in advance of the
live production starting to avoid them appearing on the program output incorrectly.
Most broadcast networks have guidelines and advice on the use of video, images, music,
logos and on screen text so it is best to check beforehand when planning a production. Do
not use copyright protected content until you have the relevant permissions. Information on
royalty free video, images and music is widely available, speak to your local dealer or search
for advice on the internet.

7.1 Picture-in-Picture and Downstream Key

The Picture in Picture (PIP) feature of the Key 1, Key 2, Key 3 and Key 4 layers can be used
for displaying a smaller secondary image in front of the background video layer. This smaller
PIP image can be resized, cropped, repositioned and even keyed by the user to avoid an
important part of the background video layer being covered by it.
The Down Stream Key layers (DSK 1 & DSK 2) are placed on top of all the previous layers.
These layers are typically used with Character Generator inputs for displaying titles, graphics,
lower thirds, clocks and logos. Datavideo offer several Character Generator products
(additional purchase) such as TC-200, CG-250, CG-10 and CG-500. If set up incorrectly these
DSK layers can also stop the video layers behind them from being displayed properly.
The SE-4000 has six dedicated keyers, Key1, Key2, Key3, Key4, DSK 1 and DSK 2. All six
keyers can be active simultaneously. In the following sub-sections, we will provide you with
descriptions of different keyer settings and ways to access them.
