You can have as many streams from the device as you want. They can have different resolutions, bit rates, and formats. The term one filter means all streams have the same Osprey custom properties. Specifically, cropping, logos (watermarks), and NTSC Closed Caption rendering settings work the same for all streams on the device when the Multiple Instances option is selected.

The advantage of this mode is that it is simpler. We recommend this mode if you don’t use Osprey custom cropping, logos, or closed captions, or if all streams have the same settings.

This setting affects all devices served by the currently accessed driver.

Multiple filters

Use this mode if you are using Osprey custom cropping, sizing, logos (watermarks), and NTSC Closed Caption rendering, and want each stream to have separate settings for these items.

This mode is definitely more complicated than the one filter option just described – so only use it if you are sure you need it.

Note: You do not have to use the Multiple Filters mode unless you specifically want different crop, size, logo, or closed caption settings on different streams. If you want these settings to be consistent on all streams for a particular Osprey card, use the Multiple Instances option.

The term “multiple filters” refers to the method of saving and accessing these different settings. You can have 1 to 10 different filters, each holding different settings. The number of filters is determined by the edit box in the picture above Show [4] filters per device.

For example, if you have 4 filters per device, each with separate crop, size, logo, and caption settings and the underlying device has the name Osprey 240 Video Device 1, when you open a list of capture devices with SimulStream enabled, Osprey 240 Video Device 1.1, Osprey 240 Video Device 1.2, and …1.3 and …1.4 appear.

To set the custom properties for one of these filters, select it from the device list and open the driver properties dialog. The title at the top of the window confirms you are setting up, for example, Osprey 240 Video Device 1.2. When you set crop, size, logo, and caption settings, they are saved separately for Device 1.2 and do not affect Devices 1.1, 1.3, or 1.4. Settings that are not per-filter – such as Reference Size or the Video Proc Amp settings –affect all filters on the underlying Osprey 240 Video Device 1.

Later, whenever you select one of the four filters as your capture filter, the Osprey custom crop, logo, and caption settings previously set for that filter is selected automatically.

This setting affects all devices served by the currently accessed driver. The driver prompts you to restart the system or your application if this is needed.
