Setup

1. Install @remotion/lambda

bash
npm i @remotion/lambda
bash
npm i @remotion/lambda

Also update all the other Remotion packages to have the same version: remotion, @remotion/cli and others.

note

Make sure no package version number has a ^ character in front of it as it can lead to a version conflict.

Your package.json should look like the following:

json
"@remotion/cli": "3.0.0", // Replace 3.0.0 with the current version
"@remotion/lambda": "3.0.0", // Remove any `^` character
// ...
"remotion": "3.0.0",
json
"@remotion/cli": "3.0.0", // Replace 3.0.0 with the current version
"@remotion/lambda": "3.0.0", // Remove any `^` character
// ...
"remotion": "3.0.0",

2. Create role policy

  • Go to AWS account IAM Policies section
  • Click on "Create policy"
  • Click on JSON
  • In your project, type npx remotion lambda policies role in the command line and copy it into the "JSON" field on AWS.
  • Click next. On the tags page, you don't need to fill in anything. Click next again.
  • Give the policy exactly the name remotion-lambda-policy. The other fields can be left as they are.

3. Create a role

  • Go to AWS account IAM Roles section
  • Click "Create role".
  • Under "Use cases", select "Lambda". Click next.
  • Under "Permissions policies", filter for remotion-lambda-policy and click the checkbox to assign this policy. Click next.
  • In the final step, name the role remotion-lambda-role exactly. You can leave the other fields as is.
  • Click "Create role" to confirm.

4. Create a user

  • Go to AWS account IAM Users section
  • Click Add users
  • Enter any username, such as remotion-user.
  • Check the "Access key - Programmatic access" option.
  • Don't check the Management console access option. You don't need it.
  • Click "Next: Permissions", then "Next: Tags", then "Next: Review" without changing any settings.
  • Click "Create user", and ignore the warning that might appear.
  • Reveal the Secret access key.
  • Add a .env file to your project, and insert the following contents, using the credentials you just copied:
.env
txt
REMOTION_AWS_ACCESS_KEY_ID=<Access key ID>
REMOTION_AWS_SECRET_ACCESS_KEY=<Secret access key>
.env
txt
REMOTION_AWS_ACCESS_KEY_ID=<Access key ID>
REMOTION_AWS_SECRET_ACCESS_KEY=<Secret access key>

5. Add permissions to your user

  • Go to AWS account IAM Users section
  • Select the user you just created.
  • Click "Add inline policy" on the right of the screen under "Permissions policies".
  • Click the tab "JSON".
  • Enter in your terminal: npx remotion lambda policies user and copy into the AWS text field what gets printed.
  • Give the policy a name. For example remotion-user-policy, but it can be anything..
  • Click "Create policy" to confirm.

6. Optional: Validate the permission setup

  • Run npx remotion lambda policies validate

For the following steps, you may execute them on the CLI, or programmatically using the Node.JS APIs.

7. Deploy a function

Deploy a function that can render videos into your AWS account by executing the following command:

bash
npx remotion lambda functions deploy
bash
npx remotion lambda functions deploy

The function consists of necessary binaries and JavaScript code that can take a serve URL and make renders from it. A function is bound to the Remotion version, if you upgrade Remotion, you need to deploy a new function. A function does not include your Remotion code, it will be deployed in the next step instead.

8. Deploy a site

Run the following command to deploy your Remotion project to an S3 bucket. Pass as the last argument the entry point of the project.

bash
npx remotion lambda sites create src/index.ts --site-name=my-video
bash
npx remotion lambda sites create src/index.ts --site-name=my-video

A serveUrl will be printed pointing to the deployed project.

When you update your Remotion video in the future, redeploy your site. Pass the same --site-name to overwrite the previous deploy. If you don't pass --site-name, a unique URL will be generated on every deploy.

9. Check AWS concurrency limit

Check the concurrency limit that AWS has given to your account:

npx remotion lambda quotas
npx remotion lambda quotas

By default, it is 1000 concurrent invocations per region. However, new accounts might have a limit as low as 10. Each Remotion render may use as much as 200 functions per render concurrently, so if your assigned limit is very low, you might want to request an increase right away.

10. Render a video

Take the URL you received from the step 8 - your "serve URL" - and run the following command. Also pass in the ID of the composition you'd like to render.

bash
npx remotion lambda render <serve-url> <composition-id>
bash
npx remotion lambda render <serve-url> <composition-id>

Progress will be printed until the video finished rendering. Congrats! You rendered your first video using Remotion Lambda 🚀
