1
Select the <ME1>/<ME2> button → [KEY1] to [KEY4] → [Modify] tab.
2
Set [Amplitude], [Frequency], and [Speed] in [H Modulation] and [V Modulation] column.
[Amplitude] Sets the amplitude of the wave.
[Frequency] Sets the frequency of the wave.
[Speed] Sets the speed of the wave movement.
3
Select an item in [Pattern] in the [H Modulation]/[V Modulation] column.
[Sine] Selects sine waves.
[Delta] Selects delta wave.
Key output
ME1 and ME2 output the following signals.
For details, refer to “System Menu” (page 140).
f
ME1PGM, ME2PGM: Outputs program signals combined according to the transition setting.
f
ME1PVW, ME2PVW: Outputs preview signals of BKGD and KEY1 to KEY4 selected in next transition. To switch the screen to the preview screen for
chroma key adjustment of the relevant keyer, use the <ME1>/<ME2> buttons
→ [KEY1] to [KEY4] → [Chroma] tab → [Sample] column → [Chroma
PVW], and select any key from [Key1] to [Key4].
To set not to always combine for each key, use the <SYS> button on the top menu
→ [MAIN FRAME] → [ME1,2] tab → [ME1 KEYPVW]/[ME2
KEYPVW] columns.
f
ME1KEYPVW, ME2KEYPVW: Preview output dedicated for key. A key combined image is always output even when the key is not combined.To switch
the screen to the preview screen for chroma key adjustment of the relevant keyer, use the <ME1>/<ME2> buttons on the top menu
→ [Key1] to [Key4]
→ [Chroma] tab → [Sample] column → [Chroma PVW], and select any key from [Key1] to [Key4].
The key set to [On] using the <SYS> button on the top menu → [MAIN FRAME] → [ME1,2] tab → [ME1 KEYPVW]/[ME2 KEYPVW] column is
combined.
f
ME1CLN, ME2CLN: Outputs clean signals before adding key effects. These can also output key out signals used for key compositions.
f
SEL KEYPVW: Outputs the preview of the key relevant to the operation of <KEY1> to <KEY4> buttons in the KEY operation section of each ME, and
<DSK1> to <DSK4> buttons. To switch the screen to the preview screen for chroma key adjustment of the relevant keyer, use the <ME1>/<ME2>
buttons on the top menu
→ [Key1] to [Key4] → [Chroma] tab → [Sample] column → [Chroma PVW], and select any key from [Key1] to [Key4]. The
image combined with the key where the <SYS> button on the top menu → [MAIN FRAME] → [Sel KeyPVW] tab is set to [On] is output. If the button
for the key set to [Off] is selected, the image is output without the key combined.
Adjusting the luminance key/linear key
Adjust the luminance key and linear key definition.
1
Select the <ME1>/<ME2> button → [KEY1] to [KEY4] → [Key Setting] tab.
2
Set [Clip], [Gain], and [Density] in the [Key Adjust] column.
[Clip] Sets the reference level for creating key signals.
[Gain] Sets the key amplitude.
[Density] Sets the key density.
3
Select an item in [Invert] in the [Key Adjust] column.
[Off] Does not invert the key signals generated internally.
[On] Inverts the key signals generated internally.
Adjusting the chroma key
Execute sampling for the selected key source to adjust the key definition. The chroma keys KEY2, KEY3, and KEY4 require the Chromakey Software
AV-SFU60 (optional).
1
Execute sampling of the selected key source. (page 66)
2
Remove the noise in the background image. (page 66)
3
Remove the noise in the foreground image. (page 67)
4
Remove the noise in the detail areas. (page 67)
5
Fine‑tune the noise or transparency of the image. (page 68)
6
Fine‑tune the generated chroma key signal. (page 69)
