1. SPLN Effects Split This effect will squeeze the Main Video Source and Sub Video Source into a half size screen The default setting is Main Video Source on the left and the Sub Video Source on the right Select different sources for the left window by pressing different channels on the Main Video Source You could switch from left to right or right to left by pressing the LEFT or RIGHT button You could also select different sources for the left window by pressing 1 4 channel on Main source or pressing 1 4 channel on Sub source for right window PIP _ Effects Picture in Picture The Picture in Picture effect puts the selected Sub Video Source in a window on the Main Video Source Variables for this effect include window size and position Engage the effect by pressing the Picture in Picture button and verifying that the LED on the button is lit Window size 2 sizes are available change the window size by pressing the and buttons on the left of the Wipe transitions is larger is smaller There are 9 different positions that are located on the right of the Wipe transition effects Select from one of the preset locations by using the buttons On each corner use Right and Left to move the window closer to the edge or to the center This effect may also be used in conjunction with the Border keys see below This is a dual channel effect and cannot be used with any other transitions or effects F

Controls and Operations Video Source a MAIN SOURCE 2 3 4 BG The first thing to do when using the SE 500 TSE p_e A IUECE is to select the Main and Sub Video Sources 7 E 1 2 3 4 BG The source you select by pressing one of the buttons a bright red LED on the selected button lights for confirmation on the Main Source bus is what is sent to the Video output This means that you can perform cuts between sources by simply pressing different buttons The Sub Source selection determines which input will be transitioned to when using any of the transition controls Wipe and Fade and provides the video for Picture in Picture and Split functions See Using Transitions page 23 and Using Effects page 26 for more details In addition to selecting which video input channel will be present in the Main and Sub Source busses you must check the appropriate input for each channel in use See Selecting video input formats and adjusting audio levels page 18 The SE 500 has automatic input select if there is an S Video cable connected to the S Video input the channel will automatically switch to S Video input However this means that if both composite and S Video inputs are connected and there is no valid video signal present thru S Video you will see a black video when that channel is selected for output For example if you have a camcorder connected to channel 1 through the composite input and you also have channel 1
