Packing List Items Description Q’ty 1 VS-100 unit 1 2 Power adaptor 12V / 0.2A 1 3 Instruction Manual 1 Introduction Video image quality is often determined by a combination of multiple factors such as camera alignment and calibration. The location of the production and the brands of connected video devices especially under Electronic Field Production (EFP) conditions can cause variable image quality in terms of brightness, colour saturation, and white balance between different video sources.

VS-100 Output Display 10
Menu Control and Options The VS-100 is a menu driven unit. The menu is viewed as part of the output display when it has been connected to a HDMI / SDI monitor (see page 9). The menu options are scrolled by turning the Menu Dial to the left or right (See item 1 on page 8). A pointer ( ►) to the left of the menu options indicates which item is currently selected. To change / select a value gently press the Menu Dial in towards the VS-100 case, like a button.
TOOLS The TOOLS option is only available with certain VS-100 output displays. These are VECTORSCOPE, PARADE and WAVEFORM MONITOR. VECTORSCOPE related TOOLS: TRACE MEMORY SET BANDWIDTH SET UP BARS PARADE related TOOLS: TRACE MEMORY SET RGB / YCbCr WAVEFORM related TOOLS: TRACE MEMORY X ZOOM X DELAY TRACE MEMORY This option allows the current VS-100 scope trace to be saved, recalled or cleared within the unit’s memory.
X ZOOM (WAVEFORM TOOLS) This option allows the waveform display to be zoomed on the X Axis so a specific area can be examined in more detail. X ZOOM options are: 100% = The whole width of the waveform is displayed (normal view). 60% = Only 60% of the whole waveform is shown on the display. In this setting X DELAY can be used to scroll left and right across the waveform. In this way the rest of the waveform can be viewed at the same level of detail.
CONFIGURATION This option in the VS-100 Main Menu allows set up of Video Thumbnail, SDI loopthrough, Capture setting and confirmation of the VS-100 firmware revision. VIDEO THUMBNAIL Allows the option to switch the video thumbnail on the scope display between 4x3 (4:3) or 16x9 (16:9) aspect ratio when working with Standard Definition inputs. A HD input should be viewed in its native 16x9 aspect ratio.
VS-100 Quick Start Guide Black and White Balance Adjustment (VECTORSCOPE) 1. Aim the camera at a solid white background or white reference card. 2. Turn on any set lights and ensure any coloured filters are removed. We want an evenly lit white reference card or background with only true white light. 3. Select VECTORSCOPE mode on the VS-100 using the NEXT MODE option. 4. Use the camera’s auto white balance feature to white balance against the solid white background or reference white card. 5.
Luminance Adjustment (HISTOGRAM) 1. Under the same on set lighting conditions aim the camera back to the white background or ideally a grayscale reference chart which includes 100% white and absolute black. 2. Select HISTOGRAM mode on the VS-100 using the NEXT MODE option. 3. Adjust the camera’s IRIS and Neutral Density Filter to reach the desired maximum white level state. If the camera has a Zebra function you can use this to identify areas of under or over exposure too. 4.
Luminance Adjustment (WAVEFORM MONITOR) 1. Under the same on set lighting conditions aim the camera back to the white background or ideally a grayscale reference chart. 2. Select WAVEFORM mode on the VS-100 using the NEXT MODE option. 3. Adjust the camera’s IRIS and matrix to reach the desired maximum white level state. There may be a pre-selected level, such as 600mv as a standard for consistency in brightness. 4.
Colour /Hue Adjustment (PARADE RGB / YCbCr) 1. Under the same on set lighting conditions aim the camera at a colour reference chart (such as DSC labs’ Chroma Du Monde). 2. Adjust the colour level of the camera to give its image the required warmer or colder look according to your preference. 3. Select PARADE mode (RGB or YCbCr) on the VS-100 using the NEXT MODE option. 4. PARADE displays the characteristic colour levels on a scale.
Camera output after adjustments (VECTORSCOPE) 1. Under the same on set lighting conditions aim the camera at a colour reference chart (such as DSC labs’ Chroma Du Monde). 2. Select VECTORSCOPE mode on the VS-100 using the NEXT MODE option. 3. Now, the VECTORSCOPE displays the analyzed colour components. If the white balance of one camera had been altered, the VECTORSCOPE matrix can be used as a check point to ensure all cameras have been correctly aligned. 4.
VS-100 Advanced Application RGB PARADE and White Balance Adjustment i. Select PARADE mode on the VS-100 using the NEXT MODE option. Then point the camera at the white background or white reference card. ii. When the white balance is correctly adjusted, The RGB traces should be flat, balanced, and parallel to one another in a straight line. iii. When White balance is not correctly adjusted, the PARADE will show unbalanced trace. iv.
Camera Noise i. Adjust the IRIS of the camera to minimum or cap the lens. ii. Select PARADE mode on the VS-100 using the NEXT MODE option. iii. The noise value will be displayed on the chart. The thicker the value on the line chart, the greater the noise level.
Comparing color saturation among cameras i. Aiming the camera at Chroma Du Monde (Set camera to AUTO). ii. Select VECTORSCOPE mode on the VS-100 using the NEXT MODE option. iii. The VECTORSCOPE matrix displaying on VS-100 represents the colour components from the camera. iv. Use the SAVE TRACE feature under TOOLS to compare the colour components between cameras. v. When two cameras have aligned luminance, the larger the VECTOR matrix, the better color saturation it represents.
