– 61 –Chapter 5 Basic Operations — KEYMasking the key signalsMask the key signals using the mask signal of the box pattern. The following figure is the status when [Type] is set to [ForeGround], and [Invert] is set to[Off].Area where the key signal is effectiveVideo signal rangeArea masked[Right][Left][Top][Bottom][50][25][0][−25][−50][−25][−50] [25][0] [50]1 Select the / button → [KEY1] to [KEY4] → [Key Setting] tab.2 Select an item in [Mask] in the [Mask] column.f Set the mask method.[Off] Does not mask the key signals.[4:3] Masks the signals in the 4:3 aspect ratio.[Manual] Masks the area set in the [Mask Adjust1]/[Mask Adjust2] columns.3 Select an item in [Type] in the [Mask] column.f Set the image to be masked.[ForeGround] Masks the foreground and displays the background.[BackGround] Masks the background and displays the foreground.4 Select an item in [Invert] in the [Mask] column.[On] Inverts the mask signal.[Off] Does not invert the mask signal.5 Set [Left], [Top], [Right], and [Bottom] in the [Mask Adjust1]/[Mask Adjust2] column.f Set the area to be masked. The [Left] setting cannot exceed the [Right] setting (and vice versa), and the [Top] setting cannot exceed the [Bottom]setting (and vice versa).[Left] Masks the key left position.[Top] Masks the key top position.[Right] Masks the key right position.[Bottom] Masks the key bottom position.Flying keyMove, expand, and shrink the input key signals using DVE effects.In order to enable the flying key, set the key transition mode to [WIPE], and select “SQ: 47” as the wipe pattern of key transition. (page 53)When the key transition is executed, the keys are combined by the key signals set using the flying key menu. (The transition effect is fixed at MIX.)Since the flying key uses DVE effects, the image is delayed by one frame.Because the edge of the key is added before the DVE effect, the thickness of the edge changes when the size is changed.1 Select the / button → [KEY1], [KEY2] → [Flying Key Adjust] tab.2 Set [X] and [Y] in the [Position] column.[X] Sets the X coordinate of the key signal.[Y] Sets the Y coordinate of the key signal.3 Set [Size] in the [Position] column.f Set the size to change the key signal (maximum 400:400%).4 Set [X], [Y], [Z], [Aspect‑H], and [Aspect‑V] in the [Rotation] column.f This function will be available in V2.00.00 or higher.PinP compositions using the flying keySelect the / button on the top menu → [KEY1] to [KEY4] → [Key Setting] tab → [Key] column, and select [Full] in [Type] to create PinPcompositions using the flying key. (At this time, [Clip] and [Gain] in the [Key Adjust] column cannot be set.)With the full key, the image on the full screen serves as the key source signal so an edge will not be added unless a further step is taken.To add an edge, mask the key signals so that the key source signals are made smaller than the entire screen.
