Claude Edited My Entire CapCut Video (I Didn’t Touch the Timeline)

Summary
Matt Loui demonstrates an end-to-end automated workflow where Anthropic’s Claude Desktop edits a video directly inside CapCut without manual timeline manipulation. By connecting Higgsfield via MCP to generate scripts, voiceovers, images, and thumbnails, Claude edits CapCut’s local draft project files directly on macOS to sync assets, add keyframe zooms, apply text, and insert sound effects.

What is shown

• CapCut Timeline Automated by Claude [00:00 - 00:37]: Loui shows an assembled CapCut project (“EmuWar 2”) featuring synchronized stickman cartoon images, voiceover, sound effects, music, and text overlay, noting zero manual edits were made on the timeline.
• Setup & CapCut Draft File Access [00:51 - 02:35]: Creation of a project in CapCut desktop, importing voiceover and images, and prompting Claude Opus 5.5 in the Claude desktop app to modify CapCut’s project draft files (draft_info.json) directly via local disk permissions rather than GUI computer use.
• Assembled Project Review [02:40 - 03:22]: Opening CapCut to review the result edited by Claude, complete with keyframed zooms, text titles, SFX, and background music.
• Higgsfield MCP Connector Setup [04:20 - 05:18]: Configuring Claude’s settings to add a custom connector to the Higgsfield MCP server (https://mcp.higgsfield.ai/mcp) via OAuth.
• Asset Generation Pipeline [05:19 - 07:05]: Generating a 3-minute script, synthesizing voiceover with the “Benji” voice, establishing timestamp alignment, generating character reference sheets, and rendering 46 individual scene visuals via Higgsfield.
• Automated Timeline Generation & Claude Memory [07:14 - 08:29]: Claude edits “EmuWar 3” draft files from the newly generated assets. Loui shows Claude analyzing manual user adjustments to update its memory for future cuts and outputting three YouTube thumbnails.
• Claude Skill Upload [08:30 - 08:50]: Navigating to Claude’s Settings > Skills to upload an automation skill file.
• Cost Calculation [09:08 - 09:50]: Review of credits consumed in Higgsfield for images, thumbnails, and reference sheets.

Claims & numbers

• The presenter says the timeline automation requires 0 manual edits, directly editing CapCut’s local draft_info.json project file.
• The presenter claims the method functions on the free tier of Claude, though he demonstrates it using Claude Opus 5.5 on Claude Pro.
• Generating the 3-minute stickman video required 241 Higgsfield credits (46 scene images, 3 thumbnails, 2 character sheets).
• The presenter states Higgsfield costs $39/month for 1,000 credits (3.9¢ per credit), making the total generation cost for this video $9.40 (approximately $9.50).
• The presenter claims typical 3-minute video production runs range between $5.00 and $9.50.

Notable quotes

• “This entire CapCut video was edited by Claude.” [00:01]
• “Do NOT use computer use or open CapCut. Build the timeline by writing the project files directly through file access to my Mac.” [01:46]
• “So you can now create a faceless YouTube channel with no editing using Higgsfield, Claude, and CapCut.” [09:53]

Assessment
A practical tutorial demonstrating a functional pipeline that pairs Claude Desktop’s local file access with CapCut’s internal JSON project structures and Higgsfield’s MCP server. Generation and file modification steps are shown working in real time across the desktop applications.
