Please keep in mind that the VHI implementation of fxPAINT is still incomplete (when compared to the latest additions to the standard) and thus may not work as expected with all boards. fxPAINT thus can use VHI Studio and its full support for all VHI drivers to grab images or download from digital cameras.
VHI driver
Select the driver for your board, here.
Input
Here you can select the input to use on your board.
Size
Choose the size of the image to grab.
Preview

Interlace, Luminance, Chrominance, Videorecorder, NTSC
Those are videospecific options whose implementation depends on the
respective driver in use.
Grab image
Copies the current image from the memory of your videoboard to a
new project.
