Features

Scope panels

Broadcast-style monitors rendered on canvas — toggle any combination to fit your layout.

Vectorscope

Hue and saturation plot with graticule, primary targets, skin-tone indicator, and adjustable scale (0.5×–3×).

Luma waveform

Brightness distribution across the frame. Scale modes: IRE (0–100), digital (0–255), or dual overlay.

RGB waveform

Separate red, green, and blue parade traces — same scale options as the luma waveform.

RGB overlay

Combined RGB waveform with per-pixel color — useful for spotting channel separation and tint.

RGB histogram

Stacked per-channel histograms for exposure and color balance at a glance.

Selected area

Zoomed view of the current selection region — isolates detail inside your sample box.

Input sources

Bring footage in however your workflow demands — files, live screen, or camera.

File load

Drop or pick images and video files from your machine. Supports common browser-readable formats.

Screen capture

Share a window, tab, or full screen — ideal for monitoring grading apps or live production feeds.

Webcam / camera

Point a USB or built-in camera at a monitor or scene. Switch between multiple cameras when available.

Live controls

Pause and resume loaded video or live captures. Set analysis FPS from 1 to 60. Clear resets the current source.

Quick load

Click the preview + placeholder or Load to pick a file. Drag-and-drop works in most browsers.

On set & on the go

A browser vectorscope when you need a fast read — not a replacement for calibrated hardware, but ready on any device.

Reference stills

Load a white-balanced photo or exported frame and check hue, saturation, and exposure before you trust a small on-set monitor.

Real-time feeds

Screen-share a grading app or point your camera at a program display — scopes update live while you work.

Phone & tablet

Responsive stacked layout on narrow screens. Touch to select regions; collapse controls for more scope space.

Selection & sampling

Isolate a region and read precise color values for your grade.

Click or drag to sample

Drag a rectangle on the preview, or tap/click for a small fixed sample. Touch works on mobile. Scopes analyze only that region.

Average color

Live swatch with hex, RGB, and HSL values computed from the selected pixels.

Copy to clipboard

Tap any color value chip to copy hex, RGB, or HSL — ready to paste into your grading tool.

Selection size

Dimensions displayed in pixels so you know exactly what area is being analyzed.

Preview navigation

Inspect detail in the source image without leaving the scope layout.

Scroll to zoom

Mouse wheel zooms the preview toward the cursor — useful for checking fine detail in a still or paused frame.

Pan

Middle- or right-click drag pans the image when zoomed in.

Scope solo

Click any scope panel to show only that scope at full size; click again to restore your previous layout.

Display controls

Tune how scopes render to match your environment and screen size.

Sampling density

Four levels from lowest to max — trade speed for pixel-level precision on large frames.

Brightness

Dark, normal, light, or bright trace intensity — readable scopes in any room lighting.

Scope resolution

Dynamic sizing adapts panels to your viewport, or lock to fixed resolution for consistency.

Panel visibility

Toggle preview, selection info, and each scope independently. Collapse the control bar for more space on any screen.

Responsive layout

Side-by-side preview and scopes on wide displays; stacked, scrollable layout on phones and vertical monitors.
