# Modify High Quality Video Bitrates
You can change a camera's high-quality (HQ) bitrate to optimize the viewing experience.
{% hint style="danger" %}
This feature is not compatible with the [PTZ series cameras](https://www.verkada.com/security-cameras/ptz/#overview).
{% endhint %}
### Considerations
* The default HQ bitrate preset (Enhanced) uses a variable bitrate, dynamically adjusting based on the scene. High-motion scenes consume more bandwidth for better quality, while simpler scenes use less, which optimizes storage space. In contrast, other presets use a constant bitrate for HQ video.
* If you choose a higher video quality, a shorter duration of HQ video is saved for later viewing.
* Estimates are calculated based on the camera's recording history, using existing HQ footage to estimate motion levels during the retention period. If the camera has been installed for only a short time (e.g., 1 hour), there may not be enough data for Command to provide an accurate estimate.
{% hint style="info" %}
Lower the bitrate to conserve network resources and optimize performance in bandwidth-constrained environments. Increase the bitrate for areas with high motion, such as busy hallways, to ensure better video quality.

## Change the HQ video quality
{% hint style="danger" %}
You need [Site Admin](/verkada-cameras/getting-started/roles-and-permissions-for-cameras.md) permissions to change a camera's HQ video bitrate.
{% endhint %}
{% stepper %}
{% step %}
**In Verkada Command, go to All Products > Cameras.**
{% endstep %}
{% step %}
**Select a camera you want to modify.**
{% endstep %}
{% step %}
**On the right, click Settings.**
{% endstep %}
{% step %}
**Under Device > HQ Video Bitrate, select an option from the dropdown.**
{% endstep %}
{% endstepper %}
{% hint style="warning" %}
This setting does not impact SQ storage. SQ video is retained for the camera's set days of retention.
