How to Cut Video in Claude Using Cardboard, 2026

To edit video in Claude, use a video editor connector; standard chat can’t do the cutting itself. Attach your three phone clips through the connector and ask for a 30-second teaser. Review the cut before adding captions and music.

TLDR:

• Claude can’t edit video in standard chat. Use a connector, editor bridge or code.
• Specify your clip length, aspect ratio and must-keep moments. Request one change per message.
• Lock your cut before adding captions, B-roll and music to avoid timing problems.
• Budget about 5 minutes to review a 60-second recap with 10 cuts before export.
• If the connector is available on your account, attach footage through Cardboard AI (cardboard.ai) in Claude, describe your cut and preview it.

Can Claude Edit Video on Its Own?#

No, Claude can’t open, cut or render video in standard chat. To edit video in Claude, you need a connector (MCP server), desktop editor bridge or executable code. Claude directs; the connected tool edits.

Anthropic’s supported chat upload formats list documents and images, not video. A smaller file won’t solve that format restriction. For an iPhone interview, use a connected editing tool instead of uploading the video as a normal chat attachment.

What Are the Ways to Edit Video in Claude?#

You have four main routes to edit video in Claude. Choose based on your footage and comfort with code. For phone clips, use a chat connector to request a captioned teaser without writing code.

What Do You Need Before You Start Editing Video in Claude?#

To edit video in Claude, have these ready:

• A Claude account.
• The connector or local tools for your chosen route.
• Your footage organized in one folder.
• A one-sentence brief with length, aspect ratio and audience.

For Claude Code, the usual extras are a terminal, FFmpeg and a transcription model. Trim long recordings first, keeping only the material you want.

Use this brief, adding your audience:

“Create a 45-second vertical Instagram Reels clip from this 30-minute podcast, with captions. Keep the joke about pricing.”

How Do You Connect a Video Editor to Claude?#

Connect a video editor to Claude through its connectors settings:

1. Browse the directory, or add a custom connector using its remote URL.
2. Check requested permissions, then click Connect and sign in to your video tool’s account.
3. Start a new chat and follow the connector’s workflow to attach clips. For three product launch phone clips, type: “Make a 30-second launch teaser in 9:16 with captions.”

Claude connectors work across web, desktop and mobile. They can act inside connected services, so choose tools you trust.

How Do You Make a Rough Cut From a Transcript in Claude?#

To make a transcript-based rough cut in Claude Code, transcribe speech, choose what stays, then apply a timestamped cut list.

1. Extract audio with FFmpeg.
2. Transcribe with a speech model.
3. Detect silences.
4. Ask Claude for timestamped cuts.
5. Apply cuts with FFmpeg.
6. Check joins for awkward frames.

OpenAI’s Whisper model is one transcription option.

For a talking head video like a 40-minute recording, ask: “Make a 12-minute rough cut. Remove pauses longer than 0.7 seconds and false starts. Keep my meaning.” Review selections before cutting.

How Do You Write Prompts Claude Can Edit From?#

To edit video in Claude, specify the length, aspect ratio, must-keep moments, and look you want. When refining a cut, request one change per message.

• Replace “Make it better” with “Cut the intro to under 5 seconds. Start on the line about our first customer.”
• Replace “Make it cinematic” with “Use warmer color, cuts around 3 seconds each, and light music ducked under speech.”

Save successful prompts as reusable briefs for weekly podcast clips. Swap in each episode’s must-keep moment.

How Do You Add Captions, B-Roll and Music in Claude?#

Add captions, B-roll and music in Claude in separate passes after locking your cut to avoid disrupting their timing.

• Start with word-timed tracked captions. Choose a style, keep vertical-video lines short, and check names and product terms.
• Place your footage where you mention each concept, or use Cardboard’s stock B-roll on Starter and above (as of November 2026).
• Add music that drops under speech, then even out audio levels.

For a 2-minute screen recording demo, start with: “Add bold-style captions,” or try head-locked captions that stick to a speaker’s face. Next: “Show dashboard B-roll when I say ‘analytics.’” Finally: “Add quiet music under my voice.”

Review before exporting.

How Do You Turn One Long Video Into Vertical Shorts With Claude?#

To turn a long video into vertical shorts with Claude, provide the transcript and specify the clip count and length:

“Make three vertical clips from this 60-minute podcast, each 30 to 45 seconds, each with one complete idea, captions on.”

Choose clips with a hook within 2 to 3 seconds and a complete final sentence. If you’re working on turning a podcast into short clips with multiple cameras, sync angles by audio, cut to the active speaker, and reframe to 9:16.

Before exporting, check the destination’s help page for current length and file-size limits.

How Do You Review and Export a Video Edited in Claude?#

Watch your Claude-edited video before exporting. For a podcast clip, check for clipped words, mid-gesture jump cuts and drifting captions.

Check:

• Watch the first and last 3 seconds for abrupt starts or endings.
• Play every cut point to check continuity.
• Check caption spelling and audio levels, since captions matter for every video.
• Review framing in vertical versions.

Export an MP4 for publishing or, if your editing tool supports it, a timeline for finishing. Timelines keep cuts editable; MP4s combine them into one video.

What Goes Wrong When You Edit Video in Claude?#

When you edit video in Claude, unclear requests, upload errors and skipped previews can cause problems:

• For vague style requests, provide a reference, similar to editing a UGC video with captions.
• If uploads fail, check supported formats. Trim a failing 4 GB camera file or export a proxy.
• Watch the preview before client delivery.
• In a new chat, paste your brief and edit decisions.
• Set a spending cap to manage usage costs.

Use Premiere Pro or DaVinci Resolve for precise color work, complex sound design or feature-length projects, which remain hard problems for AI editors today.
