GiffyPy

A simple and fast video editor made specifically for editing screen recordings for your project README. Export to animated WebP, GIF, MP4, WebM, MOV, or MKV. Opens in under a second. Instant timeline scrubbing (no loading screens, ever).

Make editing screen recordings of your project for your README extremely fast and effortless, so you can focus on the project instead marketing.

• Resize and move an overlay crop rectangle.
• Use the rule-of-thirds visual guides to help position the crop.

Edit and arrange video segments without destructively modifying the original video.

• Split clips: Split video segments anywhere using the S key.
• Reorder clips: Drag and drop clips to reorder them on the fly.
• Trim clips: Drag clip edges to trim start and end points with live preview.

Export to WebP, GIF, MP4, WebM, MOV, or MKV.

Customize your exports with these settings:

• Framerate: Adjust from 0.5 to 60 FPS.
• Scaling / Resolution: Set the output resolution as a percentage.
• Quality: Adjust output quality settings.
• GIF palette and dithering: Use automatic palette generation with dither controls for GIFs.

Each save option has its own button.

Navigate and edit complex timelines with these controls:

• Scroll: Scroll through the timeline.
• Zoom: Use Ctrl + Wheel to zoom, or two finger zoom while using trackpad.
• Pan: Use Middle-click drag to pan through the timeline, or drag with two fingers on a trackpad.
• Frame-by-frame navigation: Use the arrow keys to move one frame at a time.

• Instant scrubbing: Generates a low-resolution image sequence of the video at import time, allowing the preview to update quickly as you scrub the timeline without loading screens. Displays low-resolution images while scrubbing for a responsive experience, then switches to the full-resolution frame as soon as you release the mouse.
• Automatic codec support: Generates background proxies for video codecs that Qt cannot natively play.

The interface is organized into three main panels:

• Shows real-time playback.
• Provides interactive crop region controls.

• Displays all clips sequentially.
• Scrub the top ruler.
• Trim clips using their handles.
• Reorder segments easily.

Fine-tune your export settings before saving:

• Format
• FPS
• Resolution scale
• Output quality

Choose how to save using one of the four export buttons: Overwrite, Numbered Copy, Save To…, or Copy to Clipboard.
