Trim and Cut Clips
Precisely trim video footage and extract the best segments without opening heavy editing software.
Resize for Platforms
Reformat and resize videos for different social media platforms — landscape, portrait, and square aspect ratios.
Quick answer: Use the Video Editor tool through ToolRouter to resize for platforms directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolEvery social media platform has different video requirements. YouTube wants 16:9, Instagram feed prefers 1:1 or 4:5, Stories and Reels need 9:16, LinkedIn works best with 1:1, and Twitter accepts multiple formats. Publishing one video across all platforms means creating multiple versions with different aspect ratios, and cropping alone loses important visual information.
ToolRouter's edit_footage skill intelligently resizes video for each platform's specifications. It handles the reframing — keeping the subject centered when converting landscape to portrait, adding tasteful letterboxing or pillarboxing when needed, and adjusting compositions so nothing important gets cropped. Render_video ensures the output meets each platform's codec and quality requirements.
This is essential for social media managers publishing content across 5+ platforms, brands with a multi-channel video strategy, and agencies reformatting client content for every distribution channel.
How to resize for platforms with Claude, ChatGPT, Microsoft Copilot, and OpenClaw
Claude handles multi-platform video resizing as a single conversational request in your terminal. Specify all target platforms and framing preferences, and Claude generates every version with intelligent reframing through one multi-step workflow. Iterate on specific platform crops through dialogue to ensure important visual elements stay in frame.
