Monitoring / Video IO

app-prefs_project-prefs-monitoring-layout-a

 

app-prefs_project-prefs-monitoring-layout-b

 

The Monitoring/Video IO preference tab configures global settings for display modes, timeline monitoring and video and audio I/O.

 

dv_alert

Note that changing many of these settings requires an application restart.

 

Enable Dual Display

app-prefs_project-prefs-monitoring-dual-display

 

If Enable Dual Display is on, the application assumes a two display configuration and configures its screen layout appropriately.

 

dv_alert

The Enable Dual Display checkbox should be on when using NVIDIA SDI direct output

DVI Order

Values :

UI(1) - Monitor(2), Monitor(1) - UI(2)

Default :

UI(1) - Monitor(2)

 

Use : All dual-display configurations.

 

This setting controls the orientation of the displays, where :

 

UI - the graphical user interface (menus, buttons etc.)
Monitor - the player, image display

 

dv_note

If the dual screen mode you configure is invalid and causes problems, you can always set the general.prefs preference file parameter dualScreenMode to false before restarting.

Monitor Anchor

Values :

Centre, Top left

Default :

Centre

 

Use : NVIDIA SDI in extended desktop mode

 

This setting is only relevant to the extended desktop mode NVIDIA SDI configuration i.e. SDI configured via the NVIDIA control panel. It is used to define the positioning of the NVIDIA SDI output in relation to the primary (UI) output, when the SDI output is a different size to the UI output i.e.

 

UI output is HD (1920x1080 pixels)
SDI output is PAL (720x576 pixels)

 

NVIDIA Display Settings

app-prefs_project-prefs-monitoring-anchor_topleft

app-prefs_project-prefs-monitoring-anchor_centre

SDI output is ID #2

Use : Top left

SDI output is ID #2

Use : Centre

Enable NVIDIA SDI Direct Output

These settings relate to the NVIDIA direct SDI monitoring output.

 

Use : Monitoring via NVIDIA direct SDI

 

dv_alert

The Enable Dual Display checkbox should be on when using NVIDIA SDI direct output

 

 

app-prefs_project-prefs-monitoring-nvidia-sdi

 

dv_note

NVIDIA direct SDI is our term for the application taking direct control of the NVIDIA card SDI monitoring signal. This means that no configuration is needed in the NVIDIA display control panel.

SDI Link

This specifies the default NVIDIA SDI colourspace and format.

 

app-prefs_project-prefs-monitoring-nvidia-sdi-sdi-link-list

 

Values :

YCrCb 422, RGB 444, YCrCb 444, Dual YCrCb 422, 12 bit YCrCb 422, 12 bit YCrCb 444

Default :

YCrCb 422

Default Format

This specifies the default NVIDIA SDI video format to use.

 

app-prefs_project-prefs-monitoring-nvidia-sdi-format-list

 

Values :

PAL, NTSC, 720p, HD 1080i, HD 1080psf, HD 1080p, 2k p, 2k i

Default :

HD 1080i

 

Always use default format for monitoring

app-prefs_project-prefs-monitoring-always-use-default

 

When enabled, the monitor is locked to the format set above and will not try and switch to a new format, even if its input changes.

 

dv_note

This is useful if your output monitoring device does not support some output formats and you wish to lock it to  a supported format.

Enable OpenGL readback to Video

app-prefs_project-prefs-monitoring-readback

 

This setting enables the OpenGL graphics on your display monitor to be sent to the video board output for display in realtime. This includes the colour grading as well as any HUD or graphs displayed.

 

dv_note

This setting is only supported for NVIDIA FX4600 graphics cards (or better) and DVS Centaurus2 video boards.

 

dv_alert

OpenGL read-back is not compatible with the Interlaced Stereo DVI setting below. When enabled, the Interlaced Stereo DVI setting will be hidden.

Interlaced Stereo DVI Output

app-prefs_project-prefs-monitoring-interlaced-dvi

 

When enabled, Interlaced Stereo DVI Output will convert the DVI signal to a left and right stereo channel mode.

 

dv_note

This stereo mode is supported on display devices like the Zalman ZM-M220W 3D LCD monitor.

 

dv_note

Interlaced Stereo mode is incompatible with OpenGL read-back and will be hidden if read-back is enabled.

Enable SDI I/O Card

Use : Video I/O and Monitoring via video I/O card

 

These settings relate to your SDI video card (e.g. Centaurus2, Bluefish Lust).

 

app-prefs_project-prefs-monitoring-sd-io-card

SDI Link

This specifies the default video card SDI colourspace and format.

 

Values :

YCrCb 422, RGB 444, YCrCb 444, Dual YCrCb 422, 12 bit YCrCb 422, 12 bit YCrCb 444

Default :

YCrCb 422

Default Format

This specifies the default video card SDI video format to use.

 

Values :

PAL, NTSC, 720p, HD 1080i, HD 1080psf, HD 1080p, 2k p, 2k i

Default :

HD 1080i

 

Always use default format for monitoring

app-prefs_project-prefs-monitoring-always-use-default

 

When enabled, the monitor is locked to the format set above and will not try and switch to a new format, even if its input changes.

 

dv_note

This is useful if your output monitoring device does not support some output formats and you wish to lock it to something supported.

Priority Format

Use : Frame based project output formats

 

This setting is only relevant if we are using a progressive (frame) based (non-interlaced) project output format.

 

If we have a progressive output format (e.g. HD 1080p), this specifies whether we set our video I/O card to output a progressive signal ("p", Match p format)  or a progressive segmented fields signal ("psf", Match psf format).

 

app-prefs_project-prefs-monitoring-sd-io-priority-format

 

Values :

Match p format

Default :

Match psf format

RS422 COM Port

Default :

1

 

This sets the workstation serial (COM) port to use for VTR control.

 

dv_note

On a DVW workstation with built-in RS422 ports, this setting is not used if the environment variable USE_DVS_VTR_IF is set.

Output Sync

This setting specifies the sync signal the video I/O card uses.

 

app-prefs_project-prefs-monitoring-sd-io-output-sync

 

Values :

Internal Sync, External Sync, Bi Level Sync, Tri Level Sync, Bi Level Sync (SD Source), Tri Level Sync (SD Source)

Default :

External Sync

 

where :

 

Internal Sync - sync is generated internally and is free-running on layoff
External  Sync - sync on input signal
Bi Level Sync - used for SD (BB -0.3V)
Tri Level Sync - used for HD  (-0.3V to +0.3V)
Bi Level Sync (SD Source) - use Bi level sync on HD project
Tri Level Sync (SD Source) - use Tri level sync on SD project

Audio Settings

Default Audio Capture Bitrate

This setting specifies the sample size for VTR audio capture.

 

app-prefs_project-prefs-monitoring-sd-io-audio-bitrate

 

Values :

16 Bit, 32 Bit

Default :

16 Bit

Use Video IO Card as Audio Monitor

This setting will enable the video I/O card as the main audio monitoring device (rather than the computer workstation audio device).

 

app-prefs_project-prefs-monitoring-sd-io-audio-monitor

 

This is a Centaurus2 video card option only.

dv_alert

This is a DVS Centaurus2 video board option only.
