In simple English
This tool takes subtitle files and turns them into hand-drawn whiteboard videos. It matches the drawing speed to the spoken words in your audio. You get an MP4 video with a warm yellow paper background and sketch lines. It helps you make explainer videos and social media clips without drawing by hand. The software is free to run on your own computer under the MIT licence.
What it is
A Python-based workflow that parses SRT (SubRip Subtitle) files and coordinates mask regions with streaming pen strokes. It generates annotation files and uses a browser-based preview tool to adjust timing before rendering.
What it is good for
Solo creators and educators who want to turn voiceover scripts or lesson transcripts into whiteboard animations without paying for commercial video software.
- Creates clean hand-drawn whiteboard animations timed to spoken words.
- Includes a local web preview tool to adjust timing and regions.
- Exports standard MP4 files ready for uploading to video platforms.
- Requires running Python scripts and setting up a virtual environment from the command line.
- Depends on having existing sketch images prepared for each scene.
- Rendering video frames is slow and needs a capable processor.
