DVO Brickwall helps reduce signal entropy making compression easier. It provides an extremely sharp cut-off beyond a user defined frequency, enabling you to create an accurately defined spectral content of material for various types of compression pre-processing.
This means that compression artefacts can be reduced and the quality of the compressed image can usually be greatly improved.
The Enable button enables the entire effect :
The DVO Brickwall effect can work in both Log and Linear space.
Values | Linear, Log |
Default | Linear |
It is important to set the Data Mode correctly for your source media.
Enable Interlaced for field based input media.
Default | Off |
Cutoff lets you control the horizontal and vertical filtering of the luminance, as a percentage of the maximum bandwidth.
A setting of 100% equals a full bypass.
Control horizontal and vertical independently. Each has :
Range | 0 - 100% |
Default | 70 |
DVO brickwall has four different filter cores, each with a different characteristic.
Values | Rectangular (Sharp), Rectangular, Circular, Diagonal |
Default | Rectangular |
Diagonal is very efficient when mastering for DCT compression algorithms like MPEG.
The Rectangular (Sharp) filter has a very sharp cut off. This can be fine-tuned using the Sharpness cutoff and a different Size of the core filter.
Values | Small, Normal, Large |
Default | Normal |
Range | 0 - 15 |
Default | 0 |
