Pro Tools provides clip-based gain for quick and easy gain matching of clips (formerly called regions in Pro Tools) from different sources in a Pro Tools session. Clip-based gain is applied pre-mixer (pre-fader and before any plug-in processing). This is especially useful when working with field recordings and sample libraries in post-production sessions.
By adjusting the clip gain for individual clips on a single track, you can match their relative gain levels so that you do not have to execute complex track volume automation to compensate.
The clip gain settings stay with the clip, which means you can move, and copy and paste clips with their corresponding clip gain settings. Clip gain settings can now be imported from AAF and OMF sequences exported from Media Composer. Likewise, clip gain settings can be exported from Pro Tools with AAF sequences (but not OMF) to be imported into Media Composer.
All clips have a clip gain of 0 dB by default. Clip gain can be adjusted from –144 dB to +36.0 dB.
You can have either static or dynamic clip gain settings for a single clip. Static clip gain simply means that there is a single gain setting for the entire clip (see Simple Clip Gain Adjustment). Dynamic clip gain means that you can have gain settings for a clip that vary over time (see Graphically Editing Clip Gain).
