Video trimmer FAQ
Why does trimming take as long as the selected clip?＋
The browser’s MediaRecorder captures the selected portion while it plays. This avoids uploads and large transcoding downloads, but makes export approximately real time.
Why is the result a WebM file?＋
WebM is the format current browsers can encode reliably through MediaRecorder. Local MP4 creation generally requires a much larger transcoding engine.
Will the output match the original exactly?＋
The clip is re-recorded using your selected bitrate and browser codec. Timing is precise to normal playback events, but this is not frame-perfect professional editing.
Which browser should I use?＋
Current Chrome or Edge provides the most consistent captureStream and MediaRecorder support. Other browsers may not support local video export.
