   5 <h1>Image Bit Depth</h1>
   6
   7 <p>Most raw YUV formats use 8 bits per component (UYVY, YV12), have a fixed binary layout (V210),
   8 or use left justified binary notation (V216). For these file types there is no
   9 ambiguity about the numerical range of the pixel values.</p>
  10
  11 <p>UY16 pixel data is right justified, and can carry data at depths between 8 and 16 bits.
  12 The numerical range is not fixed, due to the variable location of the MSB in this format.</p>
  13
  14 <p>For a UY16 file, the bit depth can be selected from the "Image->YCbCr Image Depth" menu.</p>
