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 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
