Why we like it

Stands out in the aescripts library because it runs across Resolve's Edit, Color, and Fusion pages and pairs image-driven graphs with an optional background waveform. Quantity, Precision, and per-element color controls give room to dial in the look, and a demo video is available.

What is FX Oscillograph DCTL?

FX Oscillograph DCTL brings a Modulation-style effect to DaVinci Resolve, turning footage into rows of graphs driven by the image's pixel values. It can be applied on the Edit, Color, and Fusion pages.

The Quantity control sets how many graph rows appear, and a Custom Quantity option lets you define your own; a higher Quantity allows a lower Precision number without fps drops. Graphs can run vertically to represent average values of horizontal lines of pixels, and the Y Graph Mode colors the graph by Luminance, Maximum, or Minimum channel averages. Width, Pivot, Actual Values, Invert Values, and Flip further shape how graphs look.

A Scopes on BG option places a Luminance or RGB waveform behind the graphs for artistic, non color-critical use, with Power, Density, Contrast, Pivot, Add to Graph, Invert, Rotate, and Flip. The Background control reveals or fills the input image, and each element — Y Graph, RGB Graph, Scopes, and Background — carries its own Red, Green, Blue Gain, Hue, Saturation, and Gain adjustments.

Who is FX Oscillograph DCTL best for?

FX Oscillograph DCTL is best for artists building stylized, image-driven graph and waveform overlays in DaVinci Resolve across the Edit, Color, and Fusion pages.

How much does FX Oscillograph DCTL cost?

FX Oscillograph DCTL is completely free to download and use.

Key features

  • Quantity sets the number of graph rows, with a Custom Quantity checkbox for user-defined values; a higher Quantity allows a lower Precision number without fps drops
  • Y Graph Mode colors the graph by Luminance, Maximum, or Minimum channel averages, and Y and RGB graphs can be toggled on or off
  • Vertical Graphs represent average values of horizontal lines of pixels, alongside Width, Pivot, Actual Values, Invert Values, and Flip controls
  • Scopes on BG adds a Luminance or RGB waveform behind the graphs for artistic use, with Power, Density, Contrast, Pivot, Add to Graph, Invert, Rotate, and Flip
  • Background control reveals or fills the input image behind the graph, with adjustable Red, Green, and Blue fill color
  • Per-element Red, Green, Blue Gain, Hue, Saturation, and Gain adjustments for the Y Graph, RGB Graph, Scopes, and Background
  • Precision controls how many pixels are analyzed to help optimize real-time playback

Frequently asked questions

Does FX Oscillograph DCTL work with DaVinci Resolve 19?

FX Oscillograph DCTL lists compatibility with DaVinci Resolve 21, 20, and 19, so version 19 is supported. It can be applied on the Edit, Color, and Fusion pages, where it renders rows of image-driven graphs. The most recent version noted is 0.3.0, updated in August 2024, which added per-element color controls and a Density setting for the waveform. For any details beyond these listed releases and the current version, check the developer's page before you download.

Can I use FX Oscillograph DCTL on the Color and Fusion pages?

FX Oscillograph DCTL can be used on the Edit, Color, and Fusion pages in DaVinci Resolve. It renders rows of graphs based on the image's pixel values, and controls such as Quantity, Vertical Graphs, and the Y Graph Mode (Luminance, Maximum, or Minimum) shape those graphs. Per-element Red, Green, Blue Gain, Hue, Saturation, and Gain adjustments are available for the Y Graph, RGB Graph, Scopes, and Background.

Is FX Oscillograph DCTL free?

FX Oscillograph DCTL is listed here as free. Licensing terms can change over time, so check the developer's page for the current details before you download. The most recent version noted is 0.3.0, updated in August 2024, which added per-element Red, Green, Blue Gain, Hue, Saturation, and Gain controls for the Y Graph, RGB Graph, Scopes, and Background, along with a Density setting that lengthens the waveform dots. It works on the Edit, Color, and Fusion pages in DaVinci Resolve.

How does FX Oscillograph DCTL keep real-time playback smooth?

FX Oscillograph DCTL includes a Precision setting that controls how many pixels are analyzed — 1 uses each pixel, 3 uses every third pixel, 12 uses every twelfth, and so on — with fewer sampled pixels helping real-time playback. Raising the Quantity of graph rows also lets you use a lower Precision number without fps drops. Together these give room to balance detail against performance.
