To Set Up a Dissolve A dissolve transition requires that you set a background and key transition rate for the auto transition. Click Navigation Menu > Live Assist > ME > Trans > Dissolve. Tip: You can use the same procedure for a MiniME™. Enter the length of the background transition in the ME Rate field, or the length of a key transition in the Key X Rate field. Tip: You can also select a time by clicking one of the 5 through 60 buttons. Use the DisTyp knob to select Diss.
