Questions

Is my video uploaded?

No. It is decoded and encoded on your device using your browser’s built-in media engine. Long or high-resolution videos take longer on slower devices.

Which browsers work best?

Recent versions of Chrome, Edge and Safari support hardware video encoding (WebCodecs). Firefox supports most conversions. If a format cannot be encoded, the tool tells you and suggests another.
