Using the “POST” upload approach, developers can generate a basic HTML upload form that can be deployed on a website.
Since this upload approach is built on the HTTP POST method, file data is sent in one stream. In this case, an upload cannot resume if any errors occur and interrupt the upload process. Technical documentation for the POST upload approach can be found at 'Vimeo Developer: Working with Video Uploads'.
As always, you should compress your videos according to our Compression Guidelines.
