UPSTREAM KEY

Upstream Key essentially means that these are keys that are included as part of the transition, so in the transition from whatever on Preview to Program, anything that’s an Upstream Key is going to be transitioned with it.

Luma Key

• Luma key provides a way to composite a Text clip over a background clip based on the luminance levels in the video. Turn on the Luma Key, a color from the key source will be removed, revealing another background image behind it.

OUTPUT SETTING

Output Interfaces

SHARK S4 has 3 HDMI output and 1 USB output. The three HDMI outputs are default as 1 Multiview out and 2 PGM out . All outputs also can be defined as an AUX OUT from IN1, IN2, IN3, IN4, PVW, PGM, Clean PGM, Color Bar and Multiview out.

Multiview Out
The defaulted output of multiview port is the Multiview, the LED indicator of MV button in the front panel is green. User can connect it to an additional LCD display to monitor the SDI and HDMI inputs, PVW, PGM and status interface clearly. User can also configure the output of multiview port to other options according to their application requirement. When Multiview output is defined as other output, for example IN 1, user can press the MV button to quickly switch the output between multiview out and configured IN 1.

PGM Out
When one of outputs is defined as PGM out, user can connect it to an external LCD display to monitor the PGM out video. The PGM out video is the program video including the overlay images from USK and DSK. PGM Clean out is the program video removing the overlay images from DSK.

Stream Port

Encode Source
The encoded Source is PGM by default. Users can select the captured source and streaming source according to their needs and configure the output as IN1, IN2, IN3, IN4, PVW, PGM, Clean PGM, Color Bar or Multiview output. When the encoded source is defined as other outputs, such as PVW, the recording and streaming source will be PVW.

Stream Port
Users can select and set the streaming interface as USB or network port through the menu.
