Resolution
Never upscaled: a smaller source keeps its size.
QualitySource copies the video untouched when the codec and size allow it, which is fastest.
Frame rate
Audio
Trim
m:ss or seconds. Leave empty for the whole file.
How it worksNothing is uploaded. The file is read in pieces straight from your disk and encoded by your browser's own video encoder (WebCodecs), so speed depends on your machine.
Every file in the batch uses these settings.
