First of all, it is impossible to process videos efficiently in a browser environment. Even if you do it hard, it will cause the page to freeze and consume a lot of time. It makes no difference to the user whether the time is spent on preprocessing or uploading. .
Many professional video websites transcode the video after it is uploaded, or directly recommend users to process the video in advance on the upload page.
