Video Notes

The Remove Silence tool in DaVinci Resolve automatically detects quiet parts of an audio clip and removes them, tightening up pauses in things like voiceovers or dialogue.

Here’s a breakdown of the different settings...

Threshold (dB)

The volume level below which audio is considered “silence.” Any audio below this level is considered silence. For example, if you set it to -30 dB, anything quieter than -30 dB is treated as silence and removed.

Example:

• Increase (e.g. -20 dB) → removes more audio (more aggressive)
• Decrease (e.g. -40 dB) → keeps more audio (less aggressive)

Pre head (frames)

How much audio is kept before detected speech starts. This setting helps prevent cutting off the beginning of words.

• Higher value → more buffer before speech
• Lower value → tighter cuts, but risk clipping audio

Post tail (frames)

How much audio is kept after speech ends. This setting helps prevents cutting off the ends of words or breaths.

• Higher value → smoother endings
• Lower value → tighter edits

Minimum to strip (frames)

The minimum length of silence required before it gets removed.

This setting prevents tiny gaps from being removed.

• Higher value → only long silences removed
• Lower value → even short pauses removed

Cross fade audio

Adds a small fade between clips after silence is removed.

This setting helps smooth transitions and prevents abrupt audio cuts.

Quick Recommended Settings (Voiceover)

• Threshold: -30 to -35 dB
• Pre head: 3–5 frames
• Post tail: 5–10 frames
• Minimum to strip: 15–25 frames
• Cross fade: ON
