The Camera module is used to ingest a video stream from a video camera, often through the use of a (DirectShow compatible) video capture device. Right click the module to open its popup menu. The following additional menu entries are available.

Video Device

A list of all video devices available.

Video Input

If the video device has more than one input (e.g. a video capture device with HDMI and SDI inputs), you can select the active input here.

Video Standard

If the video device supports analog video standards (like PAL and NTSC), you can select the desired standard here.

Video Resolution

This submenu enumerates all video resolutions that are supported by the video device. Auto is the default setting where the setting that best matches the global video resolution will be automatically chosen. Note some capture cards only offer the correct video resolution after a video signal is connected. Other video cards, like those from Blackmagic, do not work if you do not select the same video resolution as that of the applied video signal.

Frame Rate

Set the video device frame rate. When Auto is selected (default), the global frame rate will be used. Note a camera or video capture device may only support one specific frame rate, either because it is native to its design or because it cannot convert the video signal's frame rate. In this case, selecting a different frame rate may either have no effect or result in no video. Typical examples are webcams, which often use either a fixed frame rate or adjust their frame rate (exposure) according to lighting conditions. Selecting a different frame rate for these webcams has no effect. Another example are the Blackmagic capture cards, which must be set to the exact same resolution and frame rate as the video signal (note that for progressive video this is 50 or 60 fps) or they will not work.

Frame Rate Multiplier

Converts the device's frame rate. This can be useful in case of driver errors, or when the capture card works at double the desired frame rate. Usually the default Auto settings works best.

Deinterlacing

As VidBlasterX only supports progressive video, all interlaced video signals must be deinterlaced first. Note deinterlacing uses a lot of resources so always try to use progressive video signals, or use hardware deinterlacers.

Aspect Ratio

Choose the aspect ratio of the camera video signal. Select Auto to use it's original aspect ratio.

Crop²

Allows you to crop the video source, e.g. remove overscan from an analog camera. The resulting video will be stretched to fit the original frame, maintaining the selected Aspect Ratio.

Smooth Resampling

When activated, the resampling of video frames, i.e. scaling up or down, is processed more accurately. Note this feature may consume extra resources.

Info

Shows video device's name or IP camera's URL, resolution and frame rate.
