Recording synchronous and asynchronous feeds

For best results in all workflows, use synchronous feeds, defined as follows:

  • All outputs are locked to the house reference
  • All inputs are genlocked to the house reference and at zero time

The K2 Summit Production Client and K2 Solo Media Server can record inputs that are asynchronous, with the following considerations:

  • The encoder clock and the audio clock are derived from the input signal, which enables frame accurate recording of all inputs.
  • Outputs are timed to the reference and if no reference is present, the output runs free.
  • If the input video rate does not equal the output video rate (asynchronous) then video tearing or jumping can occur when input/output synch is critical, such as in the following:
    • K2 TimeDelay
    • SD-00 or Summit E-to-E (LoopThru) mode
    • HD-00 Loopback
