Region selection

Before going live with Remotion Lambda, you need to think about into which AWS region you are deploying your function and bucket.

This document explains how to select a region and which considerations you need to make.

Available regions​

The following AWS regions are available:

  • eu-central-1
  • eu-west-1
  • eu-west-2
  • eu-west-3
  • eu-south-1
  • eu-north-1
  • us-east-1
  • us-east-2
  • us-west-1
  • us-west-2
  • af-south-1
  • ap-south-1
  • ap-east-1
  • ap-southeast-1
  • ap-southeast-2
  • ap-northeast-1
  • ap-northeast-2
  • ap-northeast-3
  • ca-central-1
  • me-south-1
  • sa-east-1

You can call getRegions() or type npx remotion lambda regions to get this list programmatically.

note

Support for regions eu-west-3, eu-south-1, eu-north-1, us-west-1, af-south-1, ap-east-1, ap-northeast-2, ap-northeast-3, ca-central-1, me-south-1, sa-east-1 has been added in v3.3.7.

Default region​

The default region is us-east-1.

Selecting a region​

There are 3 ways to select a region:

  • When using the Node.JS APIs, you have to pass the region explicitly to each function. Make sure your projects satisfy the Typescript types or follow the documentation.

  • When using the CLI, you can set the region using the REMOTION_AWS_REGION environment variable. It's best to put it in a .env file so you don't forget it sometimes.

info

The variable is called REMOTION_AWS_REGION because in Cloud providers like Vercel, AWS_REGION is a reserved environment variable name. However, Remotion does also accept the latter if you use it locally.

  • You can also pass the --region flag to all CLI commands to override the region. The flag takes precedence over the environment variable.
info

The REMOTION_AWS_REGION environment variable and --region flag do not have an effect when using the Node.JS APIs. You need to pass a region explicitly.

If you don't set a region, Remotion will use the default region.

Which region should I choose?​

Different regions have different pricing. Use the following table to get a sense of the pricing differences.

Data may be out of date, please consult the AWS Lambda Pricing page for the latest information.

RegionPrice per GB-second
ap-east-10.0000183000
af-south-10.0000176800
me-south-10.0000165334

eu-central-10.0000133334
eu-west-10.0000133334
eu-west-20.0000133334
eu-west-30.0000133334
eu-north-10.0000133334
sa-east-10.0000133334
us-east-10.0000133334
us-east-20.0000133334
us-west-10.0000133334
us-west-20.0000133334

Previously, this section mentioned differences in the amount of concurrent lambdas that can be run in a region. This is no longer the case.

Enabling regions in the AWS console​

Some regions that are supported by Remotion are not enabled by default in an AWS account. If you get a message:

The security token included in the request is invalid
The security token included in the request is invalid

see [here]

Other considerations​

  • The function and S3 bucket must be in the same region to eliminate latency across datacenters. Rendering with functions and buckets that have mismatching regions is not supported

  • You may deploy your whole architecture to different regions to further increase the amount of renders you can make concurrently. This has the advantage of higher redundancy, but a potential drawback of hitting a non-warm function.

  • Some regions are more expensive than others (for example af-south-1). Consult the Lambda Pricing page from AWS.

  • Some regions are disabled by default and you need to enable them in your AWS account before you can use them.
