# VP9 video codec support

${color}[#676767](**Our Windows and Linux users are now able to choose their preferred video codec between VP8 and VP9 when sharing a screen, a portion of screen or a single window.**)

### How to change the preferred video codec?

1. Go to the App.
2. Click on the **Cog** icon.
3. Go to **Preferences**.
4. Select the **Screen sharing** tab.
5. Click on the **Preferred video codec** menu to switch the video codec.


###### Why choosing the VP9 video codec?

* Thanks to VP9 better compression, sharing any content will end up consuming less bandwidth than with the default video codec, VP8.
* However, VP9 generally uses more CPU resources than VP8.
* We recommend that you switch to VP9 if you often share HQ content (4k and 8k) and/or share with multiple participants.

###### Important to know

* The option needs to be selected by the session's host.
* If during the session blurriness, delays and low quality display are experienced, please first go through the [Latency](/en/article/try-this-in-case-of-latency-during-a-session-1t77b6y/) steps to discard an internet connection, VPN or CPU issue before switching to the VP9 video codec.
