GreenMachine always operates in Frame Sync Mode. The processing delay depends on the input format, output format, and frame-rate conversion.

When the reference signal is asynchronous, the overall processing delay increases because the output must be aligned to the reference signal.

Asynchronous Reference
  • Processing Delay = 1 Frame + Reference Alignment
  • Maximum total delay = up to 2 frames

Notes

  • GreenMachine always operates in Frame Sync Mode.
  • The values above represent the internal processing delay under synchronous reference conditions.
  • With an asynchronous reference, an additional frame of delay may be introduced while aligning the output to the reference.
  • The maximum total latency is therefore up to two frames.
