We will introduce the double-speed playback function, which is often requested when using videos in training and e-learning.
Until now, it has been possible to add a double-speed playback function by setting the plugin for the Players module in the Video Cloud administration screen using the code sample published [here](https://player.support.brightcove.com/code-samples/brightcove-player-sample-variable-speed-playback.html “here”).
From the latest Brightcove Player version 6.35.1, the double-speed playback function is now supported on the Players module on Video Cloud. This means that you can now add the double-speed playback function to your video player without having to set up any plugins.
Let’s take a look at how to set it up.
Please note that this function is not supported in IE11, so if you expect your users to be watching in IE11, you will need to set up the plugin as usual.
## Brightcove Settings
__【Preliminary check】__
– First, go to the Video Cloud Players module and select the player you want to set the double-speed playback function for. When you click on it, the “Player Information” will be displayed on the left side, so please click on it.
– Scroll down a little and you will see “Published Player Version”, so check that the player version is 6.35.2 or later.
__【Control Settings】__
– Click on “Controls” in the left-hand menu.
– Click on the “Playback Speed” checkbox in the controls. You can see the preview player on the right-hand side load.
– When you play the preview player, “1x” will appear in the bottom right-hand corner, so click on it. A list of speed change buttons will appear.
__【Setting the speed change using the JSON editor】__
– Click on “JSON Editor” in the left-hand menu.
– In the editor, there is a section that says “playback_rates”. The default settings are “0.5, 0.75, 1, 1.25, 1.5, 1.75, 2”. 0.5 means 0.5x speed (half the normal speed), and 2 means 2x speed (twice the normal speed). You can change the value of the speed setting displayed by changing, adding, or deleting these values.
* The values that can be set for speed vary depending on the browser specifications, but as of August 2019, most are between 0.0625 and 16. Please set the values within this range.
– After making changes, click the “Save” button in the lower left.
__【Publication Settings】__
– After making the changes, don’t forget to click the “Publish and Embed” button in the top right corner.
– Clicking the “Publish Changes” button will change the settings for the published player.
## Finally
I hope you have confirmed that you can easily set double-speed playback from the Brightcove administration screen. As noted at the beginning, IE11 is not supported. I hope you will use this function according to the browser support status of the web page you are using.
