Video Compress Experimental
Downscale and re-encode video to WebM in your browser. Best for short clips.
Experimental & heavy. Browser-only video compression re-encodes in real time by playing the video through a canvas, so a 2-minute clip takes about 2 minutes. Output is WebM. Large videos can be slow and memory-heavy. For exact MP4 output use a desktop tool like HandBrake.
Re-encoding happens locally with Canvas + MediaRecorder. Nothing is uploaded.
