How to use a Custom Preview Component on the Document View

how do I use a custom preview component on the document view?

say i have an document

video

that i want to show the video preview on the document view
i also reference this video in another document, but when its a reference, I only want to show the

video

document title
how is this accomplished?

Just to confirm I’m understanding fully, you have a custom preview component for your

video

document type, e.g. something like on https://www.sanity.io/guides/portable-text-how-to-add-a-custom-youtube-embed-block . You’re happy to show this preview in

video

, but when you add a reference to the document type you don’t want to see it. Is that correct? What kind of preview does the reference currently show?

yes...

here's some screens

Video document... would like the preview here

When referenced ... this is fine

the reason the reference looks ok, is because I removed the

preview

from the schema, otherwise it was trying to load the videoPreview component

Thanks for the shots, always helps! 🙂 Have you considered adding a video object to your video document (under a different name)? That should let you show the preview on the document but just the title in the reference 📽️
This would require loading the preview component in the object instead.

i had not considered that ... so making a

video

object that goes inside the

video

document. does the object only contain the URL for the video? (i'm sourcing from vimeo)

Yep, I’d say so, unless you want to add more data that specifically belongs to the video like a title or caption etc.

well, i would think i could just use the

document

title... since the document is really about the video

One thing you could consider is whether you need that kind of data in the document where you reference the video.

been thinking the same thing ...

99% of the time, i'm probably also the document editor, and i'll know the video already

however, i do see a scenario down the road where I use this dataset as a source for another Sanity project, and the people using that project will need a visual reference to what the video looks like
