ITS REALLY NICE TO HEAR YOUR DESIGN AS A SONG.

Top notch

Process note: 🌑 Echo is a black screen where every sound sends a wave of light through the scene in real depth.

🎞️ Starting footage: one licensed stock clip of a temple corridor from invideo's stock library. The sound is original, synthesised for this piece. The voiceover is my own.

💬 What I asked for: a black screen where each ping lights the scene by distance, built from a depth map, with controls for each wave, afterglow, wave thickness, contour lines, outlines, colour and a final reveal.

🛠️ What was built: a depth map (Depth Anything Video), two "Echo" custom effects on the depth map (a Multiply layer for light and an Add layer for glow), an "Echo colour" effect on the footage, and keyframes for six waves and the reveal. The first build was done by Claude, connected to invideo Editor through invideo's MCP server.

🎚️ Refinement: I asked invideo's own agent (Agent Two Lite) in the editor to raise Afterglow from 0.14 to 0.3 on both Echo effects. It made the change on the timeline, and that conversation is shown in the video. I also tried a longer afterglow and a gold colour, both shown.

✅ All building and the final cut were done in invideo Editor.

Wow ✨
