DVO Dirt Map is an advanced dust and dirt concealer, also capable of repairing other blemishes in film. It will use Infra-Red (IR) data taken from the alpha channel of the film clip as a hit signal.
Use the Enable button to enable/disable the tool :
Use the View dropdown to visualise the IR channel and parameter setup.
This is the default state and will show the result of processing with the set parameters,
Paint the image red where the DVO Dirt Map has interpreted the IR channel as dirt.
This is a good way to begin while setting the tool up.
Paint the image red where the DVO Dirt Map has processed the image.
The greater the red intensity, the more difference versus the source image.
This defines how to interpret the dirt map alpha :
- As dark dirt on bright background
- As bright dirt on a dark background
Auto | Auto-detect |
Dirt on White | Bright background |
Dirt on Black | Dark background |
Film with high density may leave traces in the alpha channel making the IR channel less useful. Enabling this will filter out the source image from the IR channel.
Enable | Filter out picture content |
Disable | Use IR channel as-is. Default |
This parameter sets the contrast amplitude of the dirt in the IR channel.
If set to high the hit signal can be considered unsafe and turn off any processing.
Use the Dirt View / Target Dirt Map to tune the parameter.
Range | 0-1.0 |
Default | 0.75 |
This parameter will filter out false positives e.g. tiny objects from the IR channel that might not be dirt.
Use the Dirt View / Target Dirt Map to tune the parameter.
Range | 0-1.0 |
Default | 0 |
This will increase the IR channel dirt signal to process slightly outside of the defined hit.
Use the Dirt View / Target Dirt Map to tune the parameter.
Range | 0-1.0 |
Default | 0.75 |
Cut Safety will reduce false positives around scene cuts by increasing the safety algorithms on the nearby frames.
The Mode option lets you choose to enable or disable this safety setting, or decide to not process the frame nearest the scene cut.
Range | 0-1.0 |
Default | 0.75 |
The Mode can be :
Disabled | Normal processing at scene cuts |
Enabled | Cut safety Enabled. Default |
Bypass | First and last frame of scene will not be processed. |
The Region of Interest (ROI) lets you prevent the processing of parts of the picture.
A requirement might be avoiding processing sprockets if the material is overscanned.
