Edit Screen Demos with Claude Opus 5.5 on Mac

Claude Opus 5.5 is already in people's editors. Talking-head takes, campus clips, and full YouTube cuts are landing on X with that model on the prompt. The hype is fair. The model can see footage and decide cuts.

If the footage is a product demo or a tutorial, the cheap path is not a screenshot loop through Premiere or Resolve. Record in ScreenKite, keep the project on your Mac, and let Opus 5.5 call 83 purpose-built editing tools. Same model you already pay for. Fewer tokens spent rediscovering the UI.

One product demo once took me an afternoon. Screen Studio was slow and thin on editing, so the clip went to Final Cut. I fixed the cuts, the animations broke, and I exported again. Two tools, two payments, one afternoon gone. Opus 5.5 on the ScreenKite timeline is the first pass I wanted that day.

What people are wiring Opus 5.5 into

Creators are putting the model on talking-head takes, campus clips, and full YouTube cuts. That is the demand. The editor you attach decides whether those tokens buy cuts or panel hunting.

Nick Spisak recorded raw clips in Tella, then had Opus 5.5 edit a full YouTube video through DaVinci Resolve 21.1 over MCP, with Hyperframes for B-roll. That is a screen-sourced talking video, then a finishing NLE.

zetabyte posted a talking-head pass: captions, camera moves, silence trim, under Opus 5.5 and ZetaCap MCP.

A later clip called Opus 5.5 gold at video editing. The writer said an intro was cut in about 15 minutes, with B-roll, text, color, echo, and silence, and claimed a small slice of a Max plan. That is their report, not a number we ran.

Another post walked through Axton Liu's test on an 83-second talking-head clip: keep the audio and captions, move the speaker into a picture-in-picture, draw animated scenes. That is Opus around a talking-head take. For a product demo you still want a timeline you keep, in the same app that recorded the screen.

Motion MCP is not a demo recorder

Higgsfield's Opus 5.5 MCP generates graphics, animates them, renders a video, and returns an After Effects project. That is the viral motion stack. It does not capture your UI, and it does not recut the cursor path you recorded this morning.

A product demo needs your screen, your mistakes, and a multi-clip timeline. Generation can dress a talking-head. It does not replace capture.

Why a tool-native timeline spends fewer tokens

Computer-use agents can click Premiere, Final Cut Pro, or Resolve. Each action is another screenshot and another click. The agent pays again to confirm the click landed. That is a long multimodal loop for a silence pass you run every sprint.

Resolve Studio 21.1 ships a native MCP server. It is a Studio feature, not in the free edition. Blackmagic lists Studio at $295, one payment, taxes and regional price vary (checked 2026-09-08). Nick's YouTube path used it. You still pay your Claude plan, and you still recorded somewhere else.

ScreenKite records and edits in one app. The agent calls named tools: a transcript cut, a chapter pass, a caption patch. One structured call replaces a hunt through panels. The saving is the missing screenshot loop.

What ScreenKite gives Opus 5.5 on a demo

• A native recorder in the same app. Capture the UI path you ship. Open the project. Do not bounce a movie into a second editor to start cutting.
• A real multi-clip timeline. Takes, voiceover, annotations, and stills sit on the same project the agent edits.
• A plan for the edits that change meaning. A timeline cut, silence, filler, and dead-air removal, generated chapters, caption import and patch, and voiceover or camera replacement return a plan on the first call. Nothing moves until the second call.
• Your Claude plan. Claude Code, ChatGPT Codex, Antigravity, Grok Build, or Kimi. The ScreenKite AI fee is $0.
• A local MP4 you share from your own Drive. Export on the Mac. Hand the file through Google Drive, Dropbox, or your host. Pro adds S3 compatible upload. Free export keeps the brand watermark and outro until Pro removes them.

People at Apple, Reddit, HubSpot, and GitHub use ScreenKite.

How it is built

• 83 purpose-built editing tools per open window. Served over local loopback, one server per window, shaped by tens of thousands of hours of video-editing practice. Opus 5.5 calls edit operations, not pixels.
• The same mutation coordinator as the buttons. An agent edit registers undo like a click.
• Propose, then commit, on named actions. The cut list comes back first on the actions above. Removing a track or an asset applies at once.
• A revision guard. An edit that expected an older project revision is rejected.
• Transcription on the Mac. WhisperKit runs on Apple Silicon. Intel uses ElevenLabs cloud transcription, set in Settings, Transcription. Audio stays on the machine unless you turn that cloud path on.
• The approval step is in the chat panel. The server never waits for a human. The Core Agent chat panel gates on each tool's risk tier. Claude Code in a terminal is not gated.

Cross-platform & Roadmap: macOS is fully native; the Windows native Beta application is now available for download (powered by a dedicated Direct3D/C++23 engine), with a Chrome extension in development.

Creators and teams choose it because it pairs ultra-fast local hardware exports and built-in link sharing with timeline AI agent editing via Claude Code, ChatGPT Codex, Antigravity, or Grok Build. Describe the cut; the agent does the trims.

Facts

Common questions

Can Claude Opus 5.5 edit a screen recording?

Yes, when the editor exposes editing tools. In ScreenKite, Claude Code with Opus 5.5 calls 83 tools on the open project. It cuts, trims, and lays out scenes on the same timeline you recorded into.

Do I need DaVinci Resolve Studio for Opus 5.5?

No. Studio MCP is one path people are posting. ScreenKite records the demo and gives the same model a tool-native timeline without a Studio seat.

Where should I point Opus 5.5 for a product demo?

People are wiring it into Tella plus Resolve, talking-head MCP stacks, and motion MCP. For a screen demo, ScreenKite records and edits in one app and gives that model 83 tools on the timeline.

Do I pay ScreenKite for Opus 5.5?

No. The ScreenKite AI fee is $0. Opus 5.5 bills to the Claude plan you already pay for.

Does the agent wait for me before it cuts?

Not by itself. A cut returns its plan first and applies on a second call. Claude Code in a terminal can send both. Tell it to show the plan, or use the chat panel inside ScreenKite, which gates on each tool's risk tier.

How do I share the demo?

Export a local MP4. Share it from your own Google Drive, Dropbox, or host. Free export carries a brand watermark and outro. Pro removes both and adds S3 compatible upload.
