Description
The camera can display a simplified waveform monitor on the monitoring screen. You can select one of 6 types of monitors and also adjust the waveform amplification.
Solution
Waveform Monitor
Displaying the Waveform Monitor
Press the WFM button
- The waveform monitor window will appear at the right of the monitoring screen on external monitors connected to one of the MON. terminals or the HDMI OUT terminal.
- You can also set MENU/EVF
[Assist. Functions] 
[Waveform Monitor] [VIDEO Output] and/or [MON.+HDMI Output] to [On] to display the waveform monitor on the respective monitoring devices.
- Alternatively, you can press an assignable button set to [WFM: VIDEO] (optional viewfinder only), [WFM: MON.+HDMI] (external monitors only), or [Waveform Monitor] (all monitoring devices at once).
- You can use the MENU/EVF [Assist. Functions] (
) [Waveform Monitor] [Position] setting to select the position of the waveform monitor on the screen (left or right side).
Configuring the Waveform Monitor
- Open the waveform monitor's [Type] submenu.
MENU/EVF [Assist. Functions] () [Waveform Monitor] [Type]
- Select the desired option and then press SET.
- If you selected [Select Line], continue the procedure to set the Y coordinate of the line you wish to display.
​Otherwise, skip to step 5 to change the gain.
- From the same submenu, select [Select Line] and then press SET.
- Enter the Y coordinate of the desired line using the keyboard screen.
- While recording, when the vertical resolution (number of horizontal lines) is 1080, you can select a value between 0 and 1079 (1-line increments); when the vertical resolution is a value other than 1080, you can select a value between 0 and the <vertical resolution - 2> (2-line increments).
- During playback, depending on the clip's resolution, you can select a value from one of the following ranges.
0 to 1079 (1-line increments)
0 to 2158 (2-line increments)
0 to 3138 (2-line increments)*
* C700 FF C700 FF PL only.
- From the same submenu select [Gain] and then press SET.
- Select the desired amplification ratio and then press SET.
- If you selected [1x], the rest of the procedure is not necessary. If you selected [2x], the display range of the waveform monitor's Y axis will be reduced by half. Continue the procedure to select the minimum luminance value (in %) shown on the Y axis.
- From the same submenu select [Y Position] and then press SET.
- Select the desired percentage and then press SET.
Options
| [Line]: |
Sets the waveform monitor to line display mode. |
| [Line+Spot]: |
The waveform of the area in the red frame is displayed in red on top of the [Line] mode waveform. |
| [Select Line]: |
The selected horizontal line will be displayed along with its waveform. |
| [Field]: |
Sets the waveform monitor to field display mode. |
| [RGB]: |
Functions like an RGB parade scope. |
| [YPbPr]: |
Functions like a YPbPr parade scope. |
NOTES
- The waveform monitor will not be affected even if a LUT is applied to the video output.
- The waveform monitor cannot be displayed while magnification is activated.
- If the [Knee] settings in the custom picture file were changed, a horizontal line will appear on the waveform monitor indicating the luminance (Y) level corresponding to the knee point.
