In this topic, you will learn how to create a player that is always on the latest pre-release version.

Why a pre-release player?

You may wish to frequently test against the latest version of Brightcove Player, including the pre-releases. This document shows you how to configure a player that will be updated every time a new pre-release is available. By setting the "version_alias": "prerelease" configuration option you can be sure this player will always have the latest prerelease version.

In the Studio's PLAYERS module you can set a player to use always be on the latest pre-release:

Set version alias in Studio

Studio will show if a player has been configured as a pre-release player:

See version alias in Studio

How it works

Whenever a new prerelease version is released for the current major version, the Player Management API republishes all players that have the prerelease version alias on their master branch.

Creating a pre-release player with an API

The following curl statement creates a player using the Player Management API to always use the latest pre-release :

curl \
  --header "Content-Type: application/json" \
  --user $EMAIL \
  --request POST \
  --data '{
      "name": "Player",
      "configuration": {
        "player": {
          "template": {
            "name": "single-video-template",
            "version_alias": "prerelease"
    }' \$ACCOUNT_ID/players

Example configuration

Following is a player that has been configured to use "version_alias": "prerelease". In this case, the latest pre-release was version 6.23.0.

  "account_id": "1507807800001",
  "compatibility": true,
  "embed_id": "default",
  "player": {
    "template": {
      "name": "single-video-template",
      "version": "6.23.0",
      "version_alias": "prerelease"
  "player_id": "ipKAiobF4S",
  "player_name": "test for \"version_alias\": \"prerelease\"",
  "updated_at": "2018-08-30T19:51:41.813Z",
  "video_cloud": {
    "policy_key": "BCpkADaw...lB71l9h"
