Trimmy
Vertical split-crop video editor. Take any video, pick two crop regions, stack them top-and-bottom into a 9:16 frame, and export optimized for social media.
The output stacks the two crops vertically into a single 9:16 video — ideal for reaction content, split-screen tutorials, gameplay + facecam, and Reels / TikToks / Shorts.
Install
pip install trimmy
Or run it without installing, using uv:
uvx trimmy
Requires ffmpeg and
ffprobeavailable on yourPATH, plus Python 3.10+.
Usage
Launch the app:
trimmy
Or open a file directly:
trimmy path/to/video.mp4
Then:
- Open or drag-drop a video.
- Position the two crop boxes on the source frame (TOP and BOTTOM).
- Adjust the split ratio by dragging the red divider.
- Trim the timeline to the segment you want.
- Pick a platform and quality preset.
- Render — ffmpeg encodes a ready-to-upload vertical video.
