Key Takeaways
- Calibration time ranges from 30 minutes to maximum display quality (6,000 points max)
- Intelligent Resolution Profiling corrects nonlinear color space areas
- Copy .cube LUT file to DaVinci Resolve LUT folder for loading into DaVinci Resolve
- Selecting ‘No LUT selected’ prevents 3D display calibration LUT from affecting DaVinci Resolve GUI display
Calibration Options
The calibration options in DaVinci Resolve with Calman include a range of calibration times and the use of Intelligent Resolution Profiling to correct nonlinear color space areas, allowing for the creation of high-quality calibrations with different numbers of measurement points. The use of Lightning LUT can produce good results on professional displays with moderate linearity, although displays with significant nonlinearity may have less satisfactory outcomes. The selection of SMPTE video range is recommended for calibrating displays that clip or compress signals above reference white. Additionally, the initiation of the 3D Cube LUT calibration process requires clicking the OK button to start the calibration. These options provide a detailed and technical approach to display calibration, ensuring innovation and precision in the calibration process.
Video Range Selection
When selecting the video range in the calibration process, users can choose the SMPTE option to account for displays that tend to clip or compress signals above the reference white, because who needs accurate representation of the full dynamic range anyway? This option is particularly useful for calibrating video displays that may not accurately reproduce the full range of brightness levels. By selecting the SMPTE range, users can ensure that signals above the reference white are not clipped or compressed, resulting in a more accurate representation of the content being displayed. This is important for achieving optimal image quality and maintaining the integrity of the original content. The SMPTE range option can be tested on the Calman Dynamic Range page, allowing users to verify the effectiveness of the calibration process.
Initiating 3D Cube LUT Calibration Process
To begin the 3D cube LUT calibration process, users can click the OK button, which initiates the calibration process. This step is crucial in optimizing the display calibration in DaVinci Resolve with Calman. Here are three key points to consider:
- Calibration Time: The process can take anywhere from 30 minutes to achieve basic calibration to the maximum display quality, which involves up to 6,000 measurement points.
- Intelligent Resolution Profiling: This feature corrects nonlinear color space areas, ensuring accurate and consistent calibration.
- Lightning LUT: This option produces high-quality results on professional displays with moderate linearity. However, displays with significant nonlinearity may yield marginal results.
By following these steps, users can achieve precise and innovative display calibration in DaVinci Resolve, enhancing the overall viewing experience.
Compatibility of Calman 3D LUT File
Compatibility of the Calman 3D LUT file is a crucial aspect to consider when working with different devices that use the .cube format, as the internal file data structure may vary, requiring conversion for compatibility. It is important to note that the .cube format LUT file produced by Calman is compatible with DaVinci Resolve and BMD HDLink Pro. However, other devices using the .cube format may have a different internal file data structure, which means that conversion is necessary to use the .cube file with these devices. This ensures that the 3D LUT file can be properly applied and utilized for display calibration purposes. By understanding the compatibility requirements and taking the necessary conversion steps, users can optimize the display calibration process and achieve accurate and high-quality results across different devices and platforms.
Loading Calman 3D LUT File into DaVinci Resolve
The process of incorporating the Calman 3D LUT file into the DaVinci Resolve software involves copying the .cube LUT file to the designated folder within the application’s directory and then accessing the Project Settings window to apply the LUT file to the appropriate monitor, color viewer, and scopes.
| Steps | Description |
|---|---|
| Step 1 | Copy the .cube LUT file to the DaVinci Resolve LUT folder |
| Step 2 | Mac Location: /Library/Application Support/Blackmagic Design/DaVinci Resolve/LUT |
| Step 3 | Windows Location: C:ProgramDataBlackmagic DesignDaVinci ResolveSupportLUT |
| Step 4 | Start or restart DaVinci Resolve |
| Step 5 | Open the Project Settings window by clicking the gear button on any DaVinci Resolve page |
| Step 6 | In the Project Settings, open the LUTs panel by clicking on Lookup Tables in the left sidebar |
| Step 7 | Select the .cube LUT file under the 3D Video Monitor Lookup Table dropdown menu |
| Step 8 | Select "No LUT selected" under the 3D Color Viewer Lookup Table dropdown menu |
| Step 9 | Select "No LUT selected" under the 3D Scopes Lookup Table dropdown menu |
| Step 10 | Click the Apply button and close the Project Settings window |
By following these steps, users can successfully load the Calman 3D LUT file into DaVinci Resolve and apply it to the desired components for display calibration.
Applying 3D LUT in DaVinci Resolve
Applying the 3D LUT in DaVinci Resolve involves selecting the appropriate .cube LUT file for the 3D Video Monitor Lookup Table, while selecting ‘No LUT selected’ for the 3D Color Viewer and 3D Scopes Lookup Table, and then clicking the Apply button in the Project Settings window. This process ensures that the 3D calibration LUT is only applied to the video monitor display and not to the GUI display or other elements in DaVinci Resolve. By selecting the specific .cube LUT file, users can apply the desired color correction or grading to their video footage. The 3D LUT file is loaded into the Project Settings, specifically in the LUTs panel, under the 3D Video Monitor Lookup Table dropdown menu. The selection process is precise and technical, allowing users to achieve optimal results in their video editing and color grading workflow.
Preventing Improper LUT Application
To ensure the accurate application of the 3D calibration LUT, it is important to select ‘No LUT selected’ for the 3D display calibration on the GUI display in order to prevent improper LUT application. This prevents the 3D calibration LUT from affecting the DaVinci Resolve GUI display. It is crucial not to directly apply the video display 3D calibration LUT to media or output nodes as this can lead to improper application to the GUI display. By selecting ‘No LUT selected’, the calibration LUT will only be applied to the video monitor, color viewer, and scopes, ensuring that the GUI display remains unaffected. Following this step will help optimize the display calibration in DaVinci Resolve with Calman.
| LUT Application | Result |
|---|---|
| Video Display 3D Calibration LUT applied to GUI display | Improper application |
| ‘No LUT selected’ for GUI display | Accurate LUT application to video monitor, color viewer, and scopes |
Validating Display Calibration in Resolve
Validating the accuracy of display calibration can be a frustrating process as DaVinci Resolve currently does not apply the loaded 3D LUT to internally generated test patterns. However, there is a way to validate display calibration through Resolve output using Calman’s Virtual LUT feature. To begin the validation process, close the Calman Calibration connection in DaVinci Resolve and click on the DDC button on the Display tab. Scroll to the 3D LUT Controls screen and check the Enable Virtual LUT box at the bottom. Then, click the Read Series button to initiate the calibration validation. This will enable you to assess the effectiveness of the display calibration by comparing the output with the expected results. By utilizing Calman’s Virtual LUT, you can ensure that the display calibration in DaVinci Resolve is optimized and accurate.
