Questions

Is my video uploaded anywhere?

No. The file is decoded and re-encoded by your browser using WebCodecs. There's no server involved — you can disconnect from the internet after the page loads.

Which setting should I pick for Instagram?

“Balanced” at 1080p and 30 fps is a good default for Reels. Instagram recompresses everything you upload, so a very high bitrate rarely helps.

Which browsers work?

Recent Chrome, Edge and Safari. Firefox works where WebCodecs video encoding is available.
