Point Grey Flea3 USB 3.0 Technical Reference 5 Video Formats, Modes and Frame Rates
5.3.4.2 FL3-U3-32S2 Custom Formats, Modes and Frame Rates
Many USB 3.0 PCI Express Gen 2.0 motherboards limit data rates to ~180MByte/s. The FlyCap2
Camera Selection dialog shows the supported PCIe bus speed. If you select a video format/mode
that requires data rates above what is supported, the camera will skip images.
For example: 1920 x 1080, 60 FPS, YUV422 = ~248 MB/s

Mode 8
Images acquired by color cameras using Mono8, Mono12 or Mono16 modes are converted to
greyscale on the camera. Users interested in accessing the raw Bayer data to apply their own
color conversion algorithm or one of the FlyCapture library algorithms should refer to Accessing
Raw Bayer Data on page 117.
