Settings: Actor

The Actor tab allows configuration of video capture settings for three input sources: Yanus CAM, USB Camera, and Video File.

Yanus CAM

A dedicated mode for integrating Yanus CAM Pro with HyperDeck devices. When a USB camera is detected with the name 'Blackmagic Design' in Windows, the mode is automatically enabled.

Settings: Actor > Yanus CAM

The camera in Yanus CAM Pro is configured to 60Hz at 720P (1280x720). However, the video output through the USB cable is upscaled and transmitted in HD format at 60Hz 1920x1080. When recording to the HyperDeck’s SD card via a record command, the video is saved in 720P resolution.

  • Backend

The USB backend is a multimedia framework that handles video capture and can be configured to use either Microsoft Media Foundation (MSMF) or DirectShow (DSHOW).

MSMF generally offers better performance and lower latency than DSHOW on newer versions of Windows. However, some USB cameras may not function properly with MSMF. Depending on the camera model, PC specifications, or Windows environment, one backend may deliver higher FPS performance than the other.

By default, Yanus CAM uses Media Foundation, while USB Camera uses DirectShow. For OBS Virtual Camera, it only appears in the capture device list when using DirectShow mode.

  • Resize Percent : Resize percentage before processing captured frames.

    • A 45% scale of the 1920x1080 input resolution from Yanus CAM Pro results in 864x486.

    • The default Resize Percent is set to optimize real-time performance without noticeably degrading facial capture quality.

USB Camera

This mode allows you to select a capture device from the list of USB cameras detected by Windows to receive video input. When recording is required, we recommend connecting your camera through OBS Studio and selecting OBS Virtual Camera as the input source.

Settings: Actor > USB Camera

USB cameras must be configured with compatible frame rate and resolution settings before being used directly in YanusLIVE.

  • Frame Rate : [ 60, 30, 59.94, 29.97 ]

The 59.94 fps and 29.97 fps options are available when configuring the camera connection. YanusLIVE internally processes these as 60 fps and 30 fps, respectively. This adjustment is intended to resolve issues where mismatched frame rate settings may prevent USB camera connections.

  • Resolution Width / Height : [ 1280x720 ] Default

  • Codec : [ MJPG ] Default

In "Actor mode: USB Camera" the codec is explicitly specified when connecting the device to prevent errors that may occur with automatic settings. In most cases, it has been confirmed that the default MJPG setting is well compatible. The specific codec must be installed on your PC. It uses the FourCC (Four Character Code) format. For more details, refer to https://fourcc.org/codecs.php.

  • Resize Percent : [ 68% ] Default

  • Set Camera Paramters : At the start of video capture in Actor mode, YanusLIVE attempts to set the specified frame rate and resolution. If the connected USB camera does not support them, the settings may be ignored.

To avoid the inconvenience of setting FPS and resolution manually when using a direct connection, we recommend the following:

Before starting Actor mode, launch OBS Studio and configure the desired FPS and resolution. Then, in YanusLIVE — without starting Actor mode — click the Connect button for OBS Studio. YanusLIVE will retrieve the FPS and resolution settings via WebSocket communication, automatically update its configuration with those settings, and start video capture.

A USB camera currently in use by OBS Studio cannot be directly connected in YanusLIVE. In such cases, simply disabling the preview in OBS Studio is not sufficient. You must locate and click the Deactivate button in OBS Studio to fully release the resource from the camera.

Video File

The only available setting in Video File playback mode is the Resize Percent option.

Settings: Actor > Video File

Common

This setting is applicable to all three video input modes

Settings: Actor > Common

  • Actor Display Frame Rate : [ 30, 60 ]

    • Sets the refresh rate for displaying frames in the Actor video.

    • For better real-time performance, a setting of 30 FPS is recommended. Data processing and streaming will continue at 60Hz when the input is 60 FPS.

  • Enable Resize Aspect : Enable adjusting the aspect ratio independently from the input source.

  • Resize Aspect Ratio : [ 16:9, 9:16, 4:3, 3:4, .... ]

    • When the aspect ratio of the input video is non-standard, the image is adjusted to the selected ratio.

    • This is typically used in cases where the camera natively captures in 4:3 but the input is received as 16:9 due to HD output standards, and needs to be converted back to 4:3.
