Sound Effects Skill
Automatically places sound effects at the right timestamps in any video by transcribing it and matching effects to the dialogue.
Before & after
Same prompt, same agent — the only difference is the skill.
You could go through your video manually and add sound effects where they make sense. You'd need to identify the moments in dialogue or action where sound effects would help, then find or create the right audio files and place them at the exact timestamps. That takes a lot of time to get the timing right. You could use a video editor to layer in the sound effects. This is pretty labor-intensive if you have lots of videos.
SOUND EFFECTS PLACEMENT REPORT VIDEO ANALYZED: "Intro to Cloud Computing" (6 min 32 sec) Transcription complete: 847 words at 60 fps EFFECTS PLACED AUTOMATICALLY (48 total) TIMESTAMP → EFFECT → REASON 00:12 → "ding-notification" → spoken "notification arrived" 00:34 → "whoosh-transition" → topic shift indicated 01:05 → "computer-boot-up" → "system starting up" 01:28 → "warning-beep" (soft) → "warning sign" 02:15 → "typing-fast" → "configuring servers" 03:42 → "success-chime" → "task completed" 04:01 → "network-connect" → "connecting regions" 04:55 → "error-buzz" → "failure scenario" ... (40 more placements with timestamps and rationale) EFFECT LIBRARY MATCHED • 24 effects from installed sound pack (default) • 12 effects from free Creative Commons library • 12 effects generated from templates (dial tones, button clicks) • Volume normalized to -3db average • Fade-in/fade-out: 200ms on all EDITOR EXPORT Premiere Pro XML export ready (File → import_effects_final.xml) Alternative: DaVinci Resolve timeline (effects_final.csv with timings) MANUAL CLEANUP NEEDED • 00:28 - "whoosh" conflict with music (consider removing) • 02:50 - Effect cuts dialogue slightly (reduce volume -2db) Estimate: 15 min custom tweaks vs. 60 min manual placement
