Video Clipper

I built Video Clipper to turn video moments into GIFs and other formats without using FFmpeg from the command line. It uses ffmpeg.wasm to run conversion in the browser.

The interface lets users choose start and end times, crop a frame, and adjust frame rate, speed, and scale. The early version transferred files to a worker, which limited input size and performance. Following a suggestion on GitHub, I adopted WORKERFS to reduce that transfer overhead.

The repository documents support for local files up to 2 GB and notes that long conversions can take too much time. The clipper code rejects GIF clips longer than 60 seconds. I use the app when I need a quick GIF.

Features

• Trim and crop video, with frame-rate, speed, and scale controls
• Create optimized GIFs and use a boomerang effect
• Export to image, video, and audio formats including GIF, PNG, MP4, and MP3
• Use local files without installing an application
