– 55 –Chapter 5 Basic Operations — KEYKey outputME1 and ME2 output the following signals.For details, refer to “System Menu” (page 125).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 forchroma key adjustment of the relevant keyer, use the / buttons → [KEY1] to [KEY4] → [Chroma] tab → [Sample] column → [ChromaPVW], and select any key from [Key1] to [Key4].To set not to always combine for each key, use the button on the top menu → [MAIN FRAME] → [ME1,2] tab → [ME1 KEYPVW]/[ME2KEYPVW] columns.f ME1KEYPVW, ME2KEYPVW: Outputs preview signals dedicated to keys. A key combined image is always output even when the key is not combined.The preview screen for chrome key adjustment is not output.The key set to [On] using the button on the top menu → [MAIN FRAME] → [ME1,2] tab → [ME1 KEYPVW]/[ME2 KEYPVW] column iscombined.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 key preview for the to buttons and to buttons operated in the KEY operation area of eachME. The preview screen for chrome key adjustment is not output. Keys set to [On] from the button on the top menu → [MAIN FRAME] → [SelKeyPVW] tab are combined to images and output. If the button for the key which set to [Off] is selected, images where keys are not combined will beoutput.Adjusting the luminance key/linear keyAdjust the luminance key and linear key definition.1 Select the / 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 keyExecute sampling for the selected key source to adjust the key definition. The chroma keys KEY2, KEY3, and KEY4 require the Chromakey SoftwareAV-SFU60 (optional).1 Execute sampling of the selected key source. (page 55)2 Remove the noise in the background image. (page 56)3 Remove the noise in the foreground image. (page 56)4 Remove the noise in the detail areas. (page 57)5 Fine‑tune the noise or transparency of the image. (page 57)6 Fine‑tune the generated chroma key signal. (page 59)Executing sampling of the selected key sourcer To execute the sampling automatically1 Select the / button → [KEY1] to [KEY4] → [Chroma] tab.2 Select an item in [Auto Compute] in the [Auto Compute] column.[Auto Compute] Executes sampling automatically.[Reset] Resets the sampled content.r To execute the sampling manually1 Select the / button → [KEY1] to [KEY4] → [Chroma] tab.2 Set an item in [Chroma PVW] in the [Sample] column.f Set the preview monitor. Change the video signals from ME1PVW/ME2PVW outputs to those for chroma key preview.The ME1KEYPVW/ME2KEYPVW outputs are fixed to normal preview.[Off] Displays the normal preview image. The sample marker is not displayed.
