If your application requires a Vimeo.com URL (e.g. https://vimeo.com/ 76979871 ) instead of the embed code, you cannot use player parameters to customize the embedded player.
This is supported:
<iframe src="https://player.vimeo.com/video/76979871?quality=720p" width="640" height="360" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>
This is not supported :
https://vimeo.com/76979871? quality=720p
Some examples of applications that only support Vimeo URLs are social media posts, WordPress themes and plugins, Wix plugins, Squarespace plugins, and other miscellaneous video embed tools within web page builders. Some tools may allow you to adjust player preferences (like autoplay, for instance) directly in their UI.
If you need help adding a player parameter, please contact us and provide the embed code you use for faster troubleshooting.
