# Displaying a 2D or 3D Vectorscope

You can display a 2D vectorscope or 3D vectorscope on the EditDesk while you use the Colour Correction soft effect. Use these vectorscopes to match colours, adjust shadows and highlights, view colour distribution, and ensure that broadcast standards are met. Because the vectorscopes appear in the Player, you can access them when you use the Colour Correction quick menu or the Colour Correction Editor.

To view colour information in either the 2D or 3D vectorscope:

1. Display the standard Player
2. From the Player Menu tabs, select Vectorscope.

   The last selected vectorscope appears.

3. To display the 2D or 3D vectorscope, select Interactive from the Standard/Interactive box.
4. From the Scope box, select the vectorscope you want to use to view the clip.

   Select: | To view:
   --- | ---
   2D | The 2D vectorscope. Use the 2D vectorscope to analyse the colour content of the clip and locate specific colours in terms of their chroma values. When you view a clip in the 2D vectorscope, you see it in terms of hue and saturation. The size and placement of the colour squares in the 2D vectorscope show the distribution of all the colours in the clip—like a colour wheel; the distance from the centre to the perimeter of the scope maps colour saturation, with the outside edge of the scope delineating pure colour.
   3D | The 3D vectorscope. Use the 3D vectorscope to both analyse the colour content of the clip and to locate specific colours in terms of their chroma and luma values. When you view a clip in the 3D vectorscope, you see it in terms of HLS (hue, lightness, and saturation). Its X, Y, and Z axes represent red, green, and blue, and the size and placement of the colour cubes show the distribution of all the colours of the clip in RGB colour space.

5. Set the following options to customize the display of the 2D or 3D vectorscope.

   Enable: | To:
   --- | ---
   Canvas | Show the vectorscope canvas. When the canvas is off, the vectorscope is transparent, but can be outlined.
   Lines | Show the vectorscope outline.

6. To set SMPTE bars for the 2D vectorscope, select an option from the Bars box.

   Select: | To match:
   --- | ---
   Bars 75% | 75% SMPTE bars. If the current project is NTSC, the bars are set to 75% by default.
   Bars 100% | 100% SMPTE bars.

7. From the Size box, select the size of the coloured squares or cubes that make up the histogram. You can display 8x8, 16x16, or 32x32 coloured dots.
8. Click Home to reset the size of the vectorscope.
