# Sources

OmniScope supports a wide range of input sources. Use the **Connect to** dialog (**Input > Connect to...**) to browse and connect available sources.

Hardware I/O sources documented here include **DeckLink / UltraStudio**, **AJA**, and **DeltaCast** SDI capture devices, alongside software and network inputs such as NDI, OFX, SRT, FFmpeg, and file-based sources.

## Live Processing Rate

In OmniScope 1.11.55 and later, live sources provide an **Analysis rate** setting under **Input Settings > Common > Live processing**. The default **Adaptive (60 / 30 / 15 fps)** mode favors the newest frame and lowers the analysis rate when the system is under load, then raises it again when performance recovers. The input signal format and source frame rate are unchanged.

You can also choose:

* **Source rate - low latency**
* **30 fps maximum**
* **15 fps maximum**
* **Buffered (previous behavior)**

{% hint style="warning" %}
QC checks and recordings use the sampled video from a live source. A lower or adaptive analysis rate can miss brief events; use file analysis when every frame must be checked.
{% endhint %}

## Favourite Sources

You can mark frequently used sources as favourites for quick access. Click the star icon on any source in the **Connect to** dialog to add it to your favourites. Favourited sources are highlighted with a golden star.

Use the star toggle button in the top-right corner of the dialog (next to list/tile view buttons) to filter the list and show only your favourite sources. This is especially useful when you have many sources available and want to quickly connect to the ones you use most often.
