Frequently Asked Questions
Are my video or audio files ever uploaded?
No. LocalVideoKit processes all media files directly in your web browser using HTML5 File APIs, WebCodecs, and WebAssembly. Your files are never sent to any server or cloud service.
What is the difference between fast and precise trimming?
Fast trimming copies streams between existing keyframes without re-encoding, so the cut may land on the nearest keyframe rather than the exact millisecond. Precise trimming re-encodes the entire selected clip so the cut lands at the exact millisecond, which takes longer and re-compresses the video.
