The Camera Module
The Camera¹ module is used to ingest a video stream from a video camera, often through the use of a (DirectShow compatible) video capture device. Note many webcams offer video in compressed form and require (much) more resources than video capture cards due to the required decompression. Right click the module to open its popup menu. The following additional menu entries are available.
A list of all video devices available, typically video capture cards and webcams.
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.
If the video device supports analog video standards (like PAL and NTSC), you can select the desired standard here.
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 main 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 Design, are even more demanding and will only work if you select the exact same video resolution and frame rate as that of the applied video signal.
Video Frame Rate
Set the video device frame rate. When Auto is selected (default), the main 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.
Video 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.
Option > Advanced Device Settings
Opens the DirectShow driver's property panel for the selected video capture device. Note not all drivers support this. The property panel is usually intended for advanced users only.
