(Audio) Delay Field
The audio Delay field gives the delay in the playout, in ms, applied to the audio track. The
delay can be positive or negative. Examples are provided for positive and negative
delays.
Positive Delay
If the delay is positive (this means the audio track starts after the video track), silence

will be added from the GX Clip IN point for the length of the delay. The audio track will
