BZBGEAR BG-MFVS61-G2 PRODUCT MANUAL
2) Transition with Effects
AUTO performs an automated switch between Preview and Program views. The timing of
the transition is set in the multiview on screen menu. The selected transition WIPE, MIX, or
FADE will be used.
T-Bar manual transition performs the selected transition but it is more flexible in timing as
the transition depends on the speed of the manual switch movement.
FTB (Fade to Black)
Pressing the FTB button will fade the current video Program source to black. The button will
flash to indicate that it’s active. When pressing the button again it acts in reverse, from
complete black to the currently selected Program video source, and the button will stop
flashing. FTB is usually used for an unexpected situation.
Note: When the PGM window display is black and stays black even after a transition, please
check if the FTB button is flashing as the new source may have had FTB enabled.
Transition Effects
MIX Transition
Pressing the MIX button selects a basic A/B Dissolve for the next transition. It is active
when the button LED is illuminated. Use the T-Bar or AUTO to operate the transition. The
MIX transition effect is shown below:
WIPE will replace the current source by another source by replacing the image from one
edge of the screen to the opposite side. It is active when the WIPE button is illuminated.
There are a total of 8 WIPE start directions.
