ME Re-Entry

Re-entry is the term used to describe the process of selecting another ME on an ME. For example, if you select ME 1 on ME 2, ME 1 is said to be re-entered onto ME 2. Re-entry takes the output of an ME and uses it as the background or key on the other ME. If you select an ME on the background bus, the ME becomes background video source of the other ME. If you select an ME on a Key Bus, the ME becomes the key source of the other ME.

Keep the following in mind:

Keep the following in mind when working with re-entries:

  • You cannot re-enter an ME onto an ME that is re-entered into the first ME unless Re-entry Loops is turned on. For example, ME 1 cannot be re-entered into ME 3 when ME 3 is already re-entered into ME 1.
  • You cannot re-enter an ME into itself.
  • Re-entry chains of more than 4 MEs can cause line drops. Any combination of MEs can be re-entered safely, as long as there are less than 5 MEs in the chain.
  • You cannot create a re-entry chain of more than 4 MEs unless the Re-entry Depth personality option is set to Warn or Allow.
