This property page is used to select the properties specifying the format and synchronization options of the video.


Select from the following options:

Video mode
Use this option to select the desired video mode from the list of modes available for the current camera. In addition to standard modes defined by the DCAM 1.31 specifications, camera-dependent partial scan modes (Format 7) can be available at the bottom of the list. Each partial scan mode retains the frame size and packet size previously selected for it. However, selecting the same partial scan mode twice will reset its parameters to maximum values, thus providing the highest resolution and frame rate available for the mode.Equivalent to the Mode property.  

Frame rate
Lets you choose the frame rate available for the currently selected Mode. Select among the following possible frame rates: 1.875 fps, 3.75 fps, 7.5 fps, 15 fps, 30 fps, 60 fps. If one of the partial scan modes (Format 7) is selected, this option will be unavailable, as the frame rate will depend on the size of the scan window and Packet size. Equivalent to the Rate property.  

Packet size
Use this option to select the number of bytes in an isochronous packet. This option is available only for partial scan (Format 7) modes and related but not necessarily indicative of the effective frame rate. Equivalent to the PacketSize property.  

Partial scan
Lets you change the size and position of the image window in a partial scan (Format 7) mode. To modify the size and position of the window, enter the desired values for the image width, height, left coordinate and top coordinate in pixels. Equivalent to the SizeX, SizeY, StartX, StartY properties.  
16-bit swap
Select this box to change the order of bytes in incoming camera frames. While outputting 16-bit pixels, some cameras can place the most significan bits of each pixel in the high-order bytes and the least significant bits in the low-order bytes. If this happens, the live image will appear scrambled. Checking this box will restore the original pixel values. Equivalent to the SwapBytes property.  
16-bit shift
Select the number of positions for the right bit shift to be applied to 16-bit pixel values in the image buffer. When displaying and saving 16- and 48-bit images, ActiveDcam assumes that pixel values are mapped to the entire 16-bit dynamic range (0-65535). Certain cameras however may output data in narrower dynamic range resulting in dark images. Selecting a non-zero bit shift will cause real-time remapping of image data. Equivalent to the BitShift property.
