(Genlock)The Reference input signal is output using the loop-through method.1 Select the button → [SYSTEM] → [Video] tab.2 Select an item in [Sync] in the [Reference] column.f Select the sync signal.[BB] Black burst signal (vertical phase of 0H)[BB Advanced]Black burst signalWhen 59.94i or 59.94p is selected: Vertical phase of 90HWhen 50i or 50p is selected: Vertical phase of 75H[Tri‑level sync] Tri-level sync signal (vertical phase of 0H)[Internal] Synchronizes with an internal reference signal (INT).Outputs the REFOUT signal (black burst signal) from the two [ terminals.]f When the system format is 1080/24PsF, [Internal] cannot be selected in [Sync] in the [Reference] column.f This unit supports synchronization signals for field frequencies that are the same as those of the system format.However, when the system format is 1080/23.98PsF, black burst signals with 10 Field ID (SMPTE318M compliant) are also supported.f When the system format is 1080/24PsF, [Tri-level sync] can only be selected.3 Select an item in [BB Setup] in the [Reference] column.f Select [7.5IRE] or [0IRE] for the setup level of the black burst signal in the internal synchronization mode.This setting takes effect when the video system is 59.94i or 59.94p. It is fixed to [0IRE] when the video system is 50i or 50p.4 Check the display in [Gen Lock] in the [Reference] column.f Check the Genlock status.[Unlocked] Not synchronized with the external sync signal or internal reference signal.[Locked] Synchronized with the external sync signal or internal reference signal.Other video signal settingsSetting the amount of delay in video effectsA delay amount can be set for the background or key video.1 Select the button → [SYSTEM] → [Video] tab.2 Select an item in [BKGD]/[Key] in the [Latency] column.[Minimum]The video is not delayed.f However, the image will be delayed by one frame (1F) when [SQ], [SL], or [3D] is selected in wipe pattern or when theflying key is selected.
