This node will update “FFMPEG Builder” and adjust the volume by percentage of all currently known audio tracks that match the conditions.
The percent of the original volume the new volume should be. If this is set to 100, then nothing will happen. If set to 0 then the audio will become muted. 200 the audio will be twice as loud etc.
All Audio Tracks
When this is checked all audio tracks will have their volume adjusted and the pattern will not be used.
This is a regular expression that will be run against the title or language code of the audio track.
The pattern is NOT case-sensitive.
This will inverse the match
