Pipeline Overview
Available from version 1.11.25.
Pipeline Overview is a live diagnostic view that shows exactly what OmniScope is doing with your signal — from the moment a frame arrives to the scopes that display it. Open it to verify at a glance which preprocessing steps, color transforms, and QC analyses are active for each connected input.
Opening Pipeline Overview
Help > Pipeline Overview
The window stays open until you close it, and its visibility is remembered across application restarts.
Reading the Graph
Each connected input gets its own horizontal lane with four nodes, connected left to right in processing order:
Input Source
The connected source and its incoming signal: resolution, frame rate, pixel format, color space, and signal range (Video / Full)
Preprocess
Every transform applied to the frame before analysis — crop, input LUT, flips, scaling, and color space conversion
Compute / QC
The analysis passes currently running on the GPU — gamut check, HDR statistics, histograms, signal statistics, and more
Scopes
The scopes in your current layout that display this input
If multiple inputs are connected, the lanes are stacked vertically — one per input. When no input is connected, the window shows No connected inputs.
What Each Node Shows
Input Source
Displays the source name (e.g. DeckLink, NDI, Video File) followed by the properties of the incoming signal. Before the first frame arrives, the node shows Awaiting frames.
Preprocess
Lists only the steps that are actually active, so you can immediately spot unintended processing:
Crop — a crop region is applied
Input LUT — an input 3D LUT is loaded
Flip H / Flip V — horizontal or vertical flip
Snapshot Blend — a snapshot is blended over the live signal
Lanczos — high-quality Lanczos scaling is in use
Scale — the frame is being resized (with the scale factor)
CSC — active color space conversion mode (DaVinci Wide Gamut or OCIO)
In / Work / Display — the OCIO input, working, and display color spaces when color management is active
If nothing is applied, the node reads Pass-through — the signal reaches the scopes untouched.
Compute / QC
Shows which analysis passes are running for this input:
Gamut Check — gamut error detection
HDR Stats — MaxFALL & MaxCLL accumulation
Blanking — blanking detection
Signal Stats — min/max and signal statistics
Histogram — active histogram channels (Y, RGB, Hue, Sat)
EBU R103 — EBU R 103 legality checking
Chroma — chroma analysis
Color Picker — active color picker probes (with the number of points)
Scopes
Lists every scope in the current layout that is fed by this input — for example Waveform, Vectorscope, CIE Plot. Scopes assigned to other inputs are not listed in this lane.
Use Cases
"Why does my signal look different in OmniScope?" — check the Preprocess node; an input LUT, color space conversion, or scale step explains discrepancies immediately
Verifying a QC setup — confirm that gamut check, HDR statistics, or blanking detection are actually enabled for the right input before starting a QC pass
Multi-input sessions — see at a glance which scopes are attached to which input, and which processing chain each signal goes through
Performance troubleshooting — a quick inventory of every compute pass currently running on the GPU
