This is a Sanity Studio v3 plugin. For the v2 version, please refer to the v2-branch.
This plugin lets you use Mux video assets in your Sanity studio.
The Mux plugin for Sanity allows you to easily upload and preview videos.

npm install sanity-plugin-mux-input
or
yarn add sanity-plugin-mux-input
- While in your project folder, run
npm i sanity-plugin-mux-input. Read more about using plugins in Sanity here.
-
Make a schema type that uses the plugin's type
mux.video, for example:export default { title: 'Video blog post', name: 'videoBlogPost', type: 'document', fields: [ {title: 'Title', name: 'title', type: 'string'}, { title: 'Video file', name: 'video', type: 'mux.video', }, ], }
- Add the
muxInputimport to your plugins:
import {defineConfig} from 'sanity' import {muxInput} from 'sanity-plugin-mux-input' export default defineConfig({ plugins: [muxInput()], })

- Get an API Access Token and enter it into the setup screen First time you use the plugin you will be asked to enter your Mux credentials.
The Mux Video API uses an Access Token and Secret Key for authentication.
If you haven't already, generate a new Access Token in the Access Token settings of your Mux account dashboard, and make sure it got permission to both read and write video and read data.
The token is stored in the dataset as a document of the type mux.apiKey with the id secrets.mux.
Having the ID be non-root ensures that only editors are able to see it.
The Mux plugin will find its access tokens by fetching this document.
When a Mux video is uploaded/chosen in a document via this plugin, it gets stored as a reference to the video document:
// example document
{
"_type": "exampleSchemaWithVideo",
// Example video field
"myVideoField": {
"_type": "mux.video",
"asset": {
"_type": "reference",
"_weak": true,
"_ref": "4e37284e-cec2-406d-973c-fdf9ab1e5598" // 👈 ID of the document holding the video's Mux data
}
}
}Before you can display videos in your frontend, you need to follow these references to fetch the asset's playback ID, which will be used to create a player. Here's an example GROQ query to expand the video reference in the example data above:
// Example for fetching data above
*[ _type == "exampleSchemaWithVideo" ] {
myVideoField {
asset-> {
playbackId,
assetId,
filename,
}
}
}
💡 For more information on querying references, refer to the documentation on Writing GROQ queries for references or on Sanity's GraphQL API.
For reference, here's an example mux.videoAsset document:
{
"_id": "4e37284e-cec2-406d-973c-fdf9ab1e5598",
"_type": "mux.videoAsset",
"assetId": "7ovyI76F92n02H00mWP7lOCZMIU00N4iysDiQDNppX026HY",

}We recommend using Mux Player to properly display your videos, through packages like @mux/mux-player and @mux/mux-player-react. Here's an example of how you can use the Mux Player to display a video in a React component:
'use client'
import MuxPlayer from '@mux/mux-player-react'
export default function MuxVideo({playbackId, title}: {playbackId?: string; title?: string}) {
if (!playbackId) return null
return <MuxPlayer playbackId={playbackId} metadata={title ? {video_title: title} : undefined} />
}💡 You can try these recommendations through the Codesandbox example.
To enable signed URLs with content uploaded to Mux, you will need to check the "Enable Signed Urls" option in the Mux Plugin configuration. This feature requires you to set the API Access Token and Secret Key (as per the Quick start section).
📌 Note: When the signed URL option is triggered, the plugin will cache a signingKeyPrivate in a private document in the dataset. This key is used by Mux to sign the uploads, and if it's incorrect your uploads will fail. If that's the case, you can delete the secrets document and try again:
# Using the Sanity CLI, delete the secrets, then re-open the plugin and configure it again
sanity documents delete secrets.muxMore information on signed URLs is available on Mux's docs
To enable static MP4 renditions, add mp4_support: 'standard' to the options of your mux.video schema type.
import {muxInput} from 'sanity-plugin-mux-input'
export default defineConfig({
plugins: [muxInput({mp4_support: 'standard'})],
})If MP4 support is enabled in the plugin's configuration, editors can still choose to enable MP4 renditions on a per-video basis when uploading new assets.
MP4 allows users to download videos for later or offline viewing. More information can be found on Mux's documentation.
To edit max_resolution_tier to support other resolutions other than 1080p, add max_resolution_tier: '1080p' | '1440p' | '2160p' to the options of your mux.video schema type. Defaults to 1080p.
import {muxInput} from 'sanity-plugin-mux-input'
export default defineConfig({
plugins: [muxInput({max_resolution_tier: '2160p'})],
})When uploading new assets, editors can still choose a lower resolution for each video than configured globally. This option controls the maximum resolution encoded or processed for the uploaded video. The option is particularly important to manage costs when uploaded videos are higher than 1080p resolution. More information on the feature is available on Mux's docs. Also, read more on this feature announcement on Mux's blog.
The encoding tier informs the cost, quality, and available platform features for the asset. You can choose between smart and baseline at the plugin configuration. Defaults to smart.
import {muxInput} from 'sanity-plugin-mux-input'
export default defineConfig({
plugins: [muxInput({encoding_tier: 'baseline'})],
})If encoding_tier: 'smart', editors can still choose to use the baseline encoding tier on a per-video basis when uploading new assets.
More information on the feature is available on Mux's documentation. Also, read more on the feature announcement on Mux's blog
If you've enabled smart encoding, you can use Mux's auto-generated subtitles feature. Unless you pass disableTextTrackConfig: true to the configuration, users will be able to choose a language to auto-generate subtitles for uploaded videos. Refer to Mux's documentation for the list of supported languages.
You can also define a default language for the upload configuration form:
import {muxInput} from 'sanity-plugin-mux-input'
export default defineConfig({
plugins: [
muxInput({
encoding_tier: 'smart',
defaultAutogeneratedSubtitleLang: 'en', // choose from one of the supported languages
}),
],
})If your videos are always spoken in a specific language and you want to include captions by default, you can use disableTextTrackConfig: true together with defaultAutogeneratedSubtitleLang to transcribe captions for every uploaded asset without needing user interaction.
Issues are actively monitored and PRs are welcome. When developing this plugin the easiest setup is:
- Fork this repo.
- Create a studio v3 project:
npm create sanity@dev-preview. Follow the prompts, starting out with the blog template is a good way to go. cdinto your project directory, runnpm install && npm start- your sanity studio should be running on http://localhost:3333.cdinto thepluginsdirectory of your project.- Fork this repo and clone your fork into the
pluginsdirectory inside your projectgit clone [email protected]:your-fork/sanity-plugin-mux-input.git. - Open
sanity.json, go to thepluginsarray and addmux-input. - Re-start the sanity studio server with
npm start. - Edit
schemas/post.jsand add follow the plugin documentation to add amux.videotype field. - Your studio should reload, and now when you edit the plugin code it should reload the studio, when you're done creating a branch, put in a PR and a maintainer will review it. Thank you!
Run the "CI" workflow. Make sure to select the main branch and check "Release new version".
Semantic release will only release on configured branches, so it is safe to run release on any branch.
On the studio-v2 branch this will result in:
- a new version on the
latestdist-tag. - running
yarn add sanity-plugin-mux-inputornpm i sanity-plugin-mux-inputwill fetch the new version. - running
sanity install mux-inputwill fetch the new version. - studio-v3 users are unaffected.
On the main branch this will result in:
- a new prerelease version on the
studio-v3dist-tag. - running
yarn add sanity-plugin-mux-input@studio-v3ornpm i sanity-plugin-mux-input@studio-v3will fetch the new version. - running
sanity install mux-inputwon't fetch the new version.
After Studio v3 turns stable this behavior will change. The v2 version will then be available on the studio-v2 dist-tag, and studio-v3 is upgraded to live on latest.
This plugin uses @sanity/plugin-kit with default configuration for build & watch scripts.
