Technical Guide
The Video Trimmer loads the video using an HTML5 Video element and provides range sliders mapped to the video's duration. When trimming, the video element seeks to the start time and plays through to the end time while a Canvas captures each frame. The canvas MediaStream, combined with the video's audio stream via Web Audio API, is fed to a MediaRecorder. The recorder captures only the selected segment, producing a trimmed video file. Frame timing is maintained by using requestAnimationFrame to sync canvas drawing with video playback. The tool handles seeking accurately by listening for the 'seeked' event before starting capture. Audio synchronization is maintained through the MediaStream architecture.
