Why Direct Video Trimming is Difficult in the Browser:
Trimming video files (extracting a segment and saving it) requires complex video decoding, seeking, and re-encoding capabilities. Browsers do not typically provide the low-level access or computational power needed for this process purely client-side within a single HTML file.
While some advanced solutions exist (like `ffmpeg.wasm` which brings FFmpeg to the browser), they involve very large external libraries that cannot be embedded in a simple, self-contained HTML file without violating common restrictions.
Recommendations for Video Trimming:
Online Video Editors/Trimmers: Use reputable online services (e.g., Kapwing, Clipchamp, Clideo) which perform the trimming on their powerful servers.
Desktop Software: Download dedicated video editing software like VLC Media Player, HandBrake, Shotcut, or DaVinci Resolve.
This page can only demonstrate video playback and time selection. A true trimming operation resulting in a new video file is beyond the scope of a basic, self-contained client-side script.
