Intelligent resource state memory recall techniques, and associated apparatus and methods, are disclosed. States of one or more video switcher resources in a resource state memory may be recalled to the same or different resources, depending on resource availability at the time of memory recall. A memory recall need not affect an on air signal. The memory may be recalled to recreate a desired program output, as defined in the memory, on a preview output of the video switcher, which leaves a current program output of the video switcher undisturbed when the memory is recalled.
