# Maximizing Image Quality

> How to maximize the image quality of your explore3D with the SVC Pro

## USB Bandwidth

### USB Bandwidth vs Network Bandwidth

DeepWater Desktop's network bandwidth usage will **not decrease** if the camera bandwidth decreases. This is because the camera streams are decoded on-device and then transmitted.

This is not the case when streaming MJPEG through dweOS. In dweOS, the frames from the cameras are sent directly as captured off the camera.

### Splitting Buses

The SVC Pro module features 4 connectors, powered by 2 separate USB buses (each bus drives 2 ports). Both dweOS and DeepWater Desktop display a **USB Port ID** for each camera, indicating exactly which bus and port you are using.

<Tip>
  To maximize bandwidth and achieve the highest quality video from two cameras, **connect each camera to its own bus**. If you connect two cameras to the same bus, their bandwidth is automatically halved, even if you set the bitrate to the maximum.
</Tip>

The USB Port ID is formatted with the bus number first, followed by the port number.

**Optimal Setup Example (Separate Buses):**

* Camera 1: `usb-3610000.usb-1.2` (Bus 1, Port 2)
* Camera 2: `usb-3610000.usb-2.2` (Bus 2, Port 2)

**Sub-optimal Setup Example (Same Bus):**

* Camera 1: `usb-3610000.usb-1.2` (Bus 1, Port 2)
* Camera 2: `usb-3610000.usb-1.1` (Bus 1, Port 1)

See [DWD Bitrate Controls](/dw-desktop/guides/image-controls#bitrate) for more information on how to improve the camera JPEG quality.

## Framerate (FPS)

We recommend streaming at **15 FPS**. This is the sweet spot for keeping file sizes manageable and bandwidth stable, while still providing a smooth piloting experience.
