(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

matching the delay duration will be inserted before the start of the audio track.

Example

In the following example, a positive delay of 10 milliseconds has been defined. Silence

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

then be played normally until the audio track OUT point.
