GiffyPy: A fast, lightweight video editor to crop and trim screen recordings for your README

Description and use

GiffyPy speeds up creating GIFs and WebP from screen recordings by removing borders, enabling instant opening, and exporting to multiple formats quickly.

Problem

Adding GIFs or animated WebP of screen recordings to READMEs is time‑consuming due to manual video editing and UI friction.

Outcome

GiffyPy reduces video editing time from ~20 minutes to under a second for opening and fast seeking, and simplifies export to multiple formats without repetitive file dialogs.

Workflow

• Open video file in GiffyPy
• Drag a box to crop out taskbar/black borders
• Trim start/end or cut middle segments
• Adjust frame rate, resolution, and quality sliders
• Export to GIF, WebP, MP4, WebM, MOV, or MKV
• Optionally overwrite original or save numbered copy
• (Future) Copy to clipboard for direct paste
