Initializing FFmpeg...
FFmpeg is the "Swiss Army Knife" of media. Beyond audio extraction, you can build:
Convert video and audio between almost any formats (MOV to MP4, FLAC to MP3) entirely client-side.
Optimize videos for the web by adjusting bitrate and CRF values to reduce file size without losing quality.
Generate high-quality animated GIFs from video segments with custom scaling and optimized color palettes.
Implement seek-accurate video trimming to allow users to cut highlights without re-uploading files.
Merge multiple video clips or images into a single video file for simple browser-based editing.
Extract frames at specific timestamps to create preview thumbnails or filmstrips for video players.
