Here is my site Read-Only: Webflow - Normas Oficiales MX

Recently I added a new field to my CMS Blog Collection. Is a Video URL field.

Now, Im trying to use it in the Custom Code field to create custom Video Schemas. However, the new created field doesn’t show in the options.

Any help to make it appear without using workarounds?

Webflow doesn’t have a way to expose field metadata, like video.title, video.thumbnails[0], etc, and for the video field specifically there isn’t a logical content url or embed url to expose, because videos are an embedly wrapper around some form of 3rd party data source ( maybe a video, maybe a twitter car, maybe a slideshow… )

For the metadata, generally you’d use separate CMS fields for name, description, thumbnail, duration.

For the contentUrl and embedUrl, you can either store those URLs separately, or you can store your videos actually as mp4’s on your own server, and create your own <video> element with it.

Read google’s spec carefully so you understand what content is suitable for contentUrl and embedUrl.

Another option is hybrid; some fields stored in the CMS, other information extracted from the video element dynamically using javascript. If you know you’re storing YouTube videos for example, and you can reach the YouTube ID, then you can infer the thumbnailUrls and possibly a few other things.
