In this free video tutorial Pro Tools Expert team member Julian Rodgers demonstrates how to convert volume automation to clip gain information and vice versa and illustrates the difference using clip gain or volume automation can make to the sound. This feature is only available in Pro Tools Ultimate.
What Difference Does It Make When You Use Clip Gain Or Volume Automation?
While both clip gain and volume automation vary the level of audio, the biggest difference between the two are when in the signal flow they happen:
Clip Gain happens pre insert, pre send. Very like the gain pot on an analogue mixer.
Volume automation is post insert, post fader, much like a fader on a mixer
Because of this clip gain will affect gates and compressors on inserts, this is only one of the effects of this difference but it is probably the most significant. Another significant difference is the fact that volume automation is accessible via the faders, especially significant if you are using a control surface.
