Problem
A vertical clip uses a shorter edit that removes dialogue pauses, but the original music ducking automation remains tied to the deleted speech and causes unnecessary volume dips.
Solution
Root Cause / Diagnostic:
Pruning dialogue segments on the timeline without linking or updating underlying music volume keyframes leaves legacy ducking automation stranded in empty timeline spaces. The music track continues to attenuate (duck) across silent gaps or jump-cut edits where dialogue once existed, creating bizarre pumping artifacts and arbitrary drops in musical momentum.
Actionable Fix:
1. Replace manual keyframe ducking with dynamic sidechain compression: route dialogue into an aux bus and use it as a sidechain trigger on the music track's compressor.
2. Set sidechain compressor parameters: Threshold at -24 dB, Ratio at 3:1 to 4:1, Attack at 20ms, and Release at 250ms for natural, responsive ducking that follows edit cuts automatically.
3. Delete orphaned clip volume keyframes across all music tracks before finalizing short-form timeline cutdowns.
Pro Tip:
Using sidechain compression or dynamic ducking plugins (such as Waves Vocal Rider or FabFilter Pro-MB) eliminates the need to manually redraw automation when trimming cuts.
