Scanlines

Use a still detailed image for the first test: Line Shift then moves only the pattern, without source motion obscuring the comparison. BMD states that Line Angle 0 gives horizontal lines.

Frequency controls density, Width controls the obscuring Color 2 bands, and Sharpness controls their boundary. These are three separate jobs. Frequency is not labeled as a literal row count or hertz.

Color 1 and Color 2 define alternating regions. Channel fields inside the colors set RGB values; Red/Green/Blue Offset below displace channels. Choose colors with zero offsets first, then inspect colored edges.

Scanlines Only outputs the pattern separately from the source image. The output remains an image. For a regular Fusion mask, use Bitmap with explicit Luminance and a neutral black-and-white pattern; black color alone does not mean transparency.

Compare Composite Type with Scanlines Only disabled. The mode chooses interaction with the source; Line Width remains a geometric control rather than an overall effect-strength slider.

The current PNG shows Scanlines Only once in Composite. Its repeated mention in BMD text is not turned into an invented second control here. The original illustration retains the fully expanded Composite Type menu.

Check fine patterns at final resolution and across several frames: Viewer zoom and later resizing may change stripe appearance. Native Resolve rendering, final pixels and alpha behavior still need separate verification.
