Trim and Cut Clips
Precisely trim video footage and extract the best segments without opening heavy editing software.
Add Background Music
Layer background music or audio tracks onto your videos with proper volume balancing and fade effects.
Quick answer: Use the Video Editor tool through ToolRouter to add background music directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolBackground music transforms flat video content into engaging, emotional experiences. The right soundtrack makes tutorials more watchable, product demos more compelling, and social content more shareable. But mixing audio properly — balancing music against dialogue, adding fades, and avoiding copyright strikes — requires both skill and the right tools.
ToolRouter's edit_footage skill layers audio tracks onto your video with intelligent volume management. It balances background music against existing dialogue so the music enhances without overpowering. Add fade-ins, fade-outs, and ducking so music drops during speech and rises during visual-only segments.
This is invaluable for content creators adding production value to their videos, businesses creating branded video content with consistent audio identity, and social media teams who know that videos with music get significantly more engagement.
