201. Basic operationsStep 2The objective of this step is to remove the noise in thebackground image.The noise is removed by carrying out this step several times.1 On the Chroma Key menu, use [F1] to display theSample sub menu.2 Use [F2] to select “Matte” (Matte image) using the Viewitem.3 Use [F3] to select “Clean BG Noise” using the Modeitem.Clean BGNoiseThe noise in the background image isremoved.4 Using the positioner, move the position of the samplemarker to the position of the noise (white dots) in thebackground image.To change the size of the sample marker, turn the rotaryencoder [Z].5 If the sample area that has been set is acceptable,press the rotary encoder [Z].The noise in the area that has been set is now removed.6 To return to the pre-sampling status after sampling hasbeen executed, press [F5].The number of operations that can be undone is oneonly.After the noise isremovedBefore the noise isremovedStep 3The objective of this step is to remove the noise in theforeground image.The noise is removed by carrying out this step several times.1 Use [F2] to select “Matte” (Matte image) using the Viewitem.2 Use [F3] to select “Clean FG Noise” using the Modeitem.Clean FGNoiseThe noise in the foreground image isremoved.3 Using the positioner, move the position of the samplemarker to the position of the noise (black dots) in theforeground image.To change the size of the sample marker, turn the rotaryencoder [Z].4 If the sample area that has been set is acceptable,press the rotary encoder [Z].The noise in the area that has been set is now removed.5 To return to the pre-sampling status after sampling hasbeen executed, press [F5].The number of operations that can be undone is oneonly.After the noise isremovedBefore the noise isremoved
