Video Output Pane Descriptions

Output Device	The list of Output Devices is dependent on the optional ClearView output modules that are installed. Four possible Output Devices are displayed in the pull-down menu: No Video Output Module – display a preview of the video Y’CbCr, RGB, ARGB, RGBA and display the GUI on the DVI/VGA display. Full Screen Desktop Output Module – display RGB or ARGB onto the GUI’s display in place of the GUI if you have the DVI output module installed. DVI Output Module – display RGB or ARGB onto the second DVI display and display the GUI on the first DVI display. Broadcast Output Module – display Y’CbCr or RGBA onto the Television/Monitor and display the GUI on the DVI/VGA display.
Video Format	The list of available resolutions and frame rates depends upon the Output module. No Video Output Module has no restrictions. Full Screen Desktop Output Module is restricted by the EDID codes defined by the GUI (1st) display’s capabilities. The DVI Output Module is restricted by the EDID codes defined by the DVI (2nd) display’s capabilities. The Broadcast Output Module is restricted by broadcast specifications provided by DVB and SMPTE.
Analog Output	Defines the type of analog output when using the Broadcast Output Module (i.e. Composite, S-Video or Component; there are about 20 different standards world-wide). The Output is sent out the chosen analog output and SDI/HD-SDI.

The No Video and the Full Screen Desktop output devices use ClearView 's VGA or DVI output to display the video sequences. These are the only Output Devices available if the optional DVI module is not installed.

If the DVI module option is installed, then the system has two DVI connectors. The first one (marked with a 1) is used to for the No Video and Full Screen outputs. The second (marked with a 2) DVI connector is used for the DVI output device.

The Broadcast output device uses the HD-SDI, SDI, Component, S-Video, or Composite output. In addition it also includes 4 stereo channels (2 in/ 2 out while playing and recording) of AES-EBU and 16 mono embedded channels. VANC data can be captured and played. VANC acts like a bigger raster size. The audio & VANC controls are turned on/off via the Configuration Settings pane.

After selecting an Output Device, a list of available video format and analog outputs for the Output Device are displayed in the Video Format pull-down menu. For example, if the Output Device is Broadcast I/O, the Video Format can be 1080i 59.94Hz, and the Analog Output should be 1080i SMPTE.

The No Video, Full Screen Desktop, and DVI output devices allow custom video resolutions and frame rates. Any video resolution can be specified; however, the software follows the display’s EDID codes. Therefore, you must attach a display that is capable of the specified resolution and frame rate.
 
Note 1: if you did not start the machine with the display connected the DVI module may not read the EDID codes correctly, you will need to reboot.

Note 2: After choosing Full Screen Desktop mode, double click in the Preview Window to toggle between full screen and GUI controls.

After a Video Format has been selected, the ClearView memory is tiled to the resolution of the selected format. Video sequences imported after this selection is made are either padded with black to the current resolution or are clipped to the current resolution. For example, if ClearView is operating in 1080i at 59.94 Hz, the resolution is 1920 x 1080 based on the industry standard. If a NTSC sized sequence is loaded, it will be centered on 1920 X 1080 and padded with black on all four sides.

The image format must be chosen next. This item is shown in the Memory-Disk Pane below. The choices are as follows:

• Y’CbCr 8-bit – this is a Broadcast I/O format
• Y’CbCr 10-bit – this is a Broadcast I/O format
• BGR 8-bit – this is a Broadcast I/O format
• RGBA 8-bit – this is a Broadcast I/O format
• RGBA 10-bit – this is a Broadcast I/O format
• ARGB 8-bit – this is a DVI I/O format
• RGB 8-bit – this format stores less bytes for DVI I/O format. The ‘A’ is added on output.

Any video sequence, regardless of its actual input image format, can be loaded into any image format. After it is inputted to a specific image format it can only be outputted to a compatible display. Any format will work in No Video Output mode.

Note: video sequences already loaded will not play if the Output Format does not match the clip’s output format when it was originally loaded. If you want to view a video sequence that was previously loaded in a different output format, then you will need to reload it. To view the properties of any video sequence, hover the cursor over the thumbnail or view the video sequences in detail mode.
