markdry

Remove watermarks from videos via drag-and-drop. Uses LaMa inpainting. SVGOMG-style UX: drop a file, draw mask rectangles, download the result.

Install

# simple-lama-inpainting pins Pillow <10; install it separately first
pip install simple-lama-inpainting --no-deps
pip install -e .
markdry serve

The browser opens at http://localhost:7777 automatically.

On first run, the LaMa model (~196 MB) is downloaded once to ~/.cache/torch/.

Requirements

• Python 3.11+
• ffmpeg and ffprobe on $PATH (brew install ffmpeg)
• Apple Silicon: CoreML/MPS is selected automatically, CPU otherwise

Usage

1. Drop a video onto the page (MP4, MOV, MKV — up to 500 MB).
2. Drag rectangles over the watermark on the preview frame.
3. Click Process. Progress streams frame-by-frame.
4. Click Download clean video when done.

Audio is preserved. Processing uses the same static mask for every frame.
