TWICK - React SDK for Building Video Editors (Captions, Timelines, Effects)

[Lomanu4]

I have been building a React-based video editing SDK tailored for apps that need to generate, edit, or enhance video content — especially AI-generated content like explainers, reels, and product showcases.

As more AI tools pump out video content, one big pain point keeps surfacing:

“How do we give users manual control over what the AI just made?”

The Problem


Most AI video tools can generate content — but they fall short when users want to fine-tune it. You get a video, but can’t easily:

• Add styled captions
• Adjust scenes
• Sync audio
• Edit the timeline
• Apply effects

So I am building a toolkit that lets you embed an editing layer right into your frontend.

What the SDK Includes


Here’s a breakdown of what the SDK offers out-of-the-box:

Media Utils

• Extract metadata (video, audio, images)
• Resize and fit media for different layouts
• Generate audio visualizers
• Extract audio from video

Media Parser

• Convert .mov / .webm ➝ .mp4
• Compress large video files
• Handle encoding seamlessly in the background

Lambda Integration

• Export videos via AWS Lambda
• Save output directly to cloud storage (S3)

Timeline Editor

• Trim, split, and arrange media layers
• Add & sync text, effects, and audio
• Timeline-based editing made React-friendly

AI-Powered Captions

• Auto-generate captions from voice/video
• Apply styled caption themes

Live Edit Canvas

• Drag, resize, rotate video elements
• Realtime sync with the timeline
• Live preview as you edit

UI Visualizer

• Panel-based editor
• Built-in state management (with undo/redo)

Effects Engine

• Canva-style animations: pop, flicker, fade, zoom
• Text effects: typewriter, staggered, bounce
• Visual filters for color grading & tone

Use Cases


This SDK is ideal for:

• AI video generation tools (ChatGPT agents, script-to-video platforms)
• Social media automation apps
• Product marketing video builders
• Internal tooling for media teams
