Broadcast Monitoring with ScopeLab
Professional video analysis for any browser tab. ScopeLab provides real-time Waveform, Vectorscope, RGB Parade, and Frame-Diff monitoring for any webpage video element.
Quick start
Monitor your footage in three moves
ScopeLab is a free Chrome extension that turns your browser into a dedicated grading reference monitor with no hardware required.
Launch the Console
Navigate to any page with a video. Click the icon to open a separate, floating analysis window. It will auto-detect the video and begin rendering scopes.
Analyze the Signal
Play or scrub the video normally. Watch the real-time feedback to identify Highlight Clipping, Color Casts, or AI Motion Spikes.
Methodology
Signal Intelligence
ScopeLab captures frames at up to 10fps, processing them locally in your browser via a separate capture thread to ensure zero impact on video playback.
The Four Scopes
Each panel provides a unique perspective on your image data, essential for broadcast-grade quality control.
- Waveform Luma Luminance distribution from 0 to 100 IRE.
- RGB Parade Color channel balance for white balance checks.
- Vectorscope Hue and Saturation clusters relative to legal targets.
- Frame Diff Pixel-level motion and temporal stability detection.
A/B Comparison
Assign videos to Source A and Source B. This allows for direct, side-by-side scope analysis of two different grades or two different AI upscaling models.
Tip
Arrange your workspace for dual monitors. Keep the video full-screen on your primary display and the ScopeLab console on your secondary display.

Mastering the Console
Waveform IRE
Monitor your black and white points. Broadcast legal range is typically 7.5 to 100 IRE. Identifying clipping here is crucial before final delivery.
Vectorscope Skin-Tone
Verify skin-tone accuracy. Check that your clusters align with the skin-tone line (approx. 75° between Red and Yellow) for natural results.
RGB White Balance
Identify unwanted color casts. If the Red channel rides significantly higher than Blue in neutral areas, your image has a warm bias.
Temporal Frame Diff
Identify AI motion artifacts. Narrow spikes in the Frame Diff scope flag "phantom frames" or temporal instability that the human eye might miss.
Browser Integration
ScopeLab works on any site with an HTML5 video tag, including Frame.io, YouTube, Vimeo, and local file previews.
Dual-Source Logic
Lock the analysis to one specific tab or source, allowing you to switch browser tabs without losing the active scope trace.
Professional Workflow
Production QC
Identify AI Drift
AI generators often shift hue or luminance across cuts. Scrub slowly through your exports to ensure that the vectorscope cluster remains stable.
Legal Broadcast Checks
Before delivering a commercial, run the export through ScopeLab to ensure no highlights exceed 100 IRE, preventing rejection during technical QC.
Compare Upscale Quality
Open your original AI clip and your upscaled version in separate tabs. Use A/B mode to see the waveform sharpen and the vectorscope tighten.
Grading with Reference
Keep a reference film trailer open in one tab. Use the RGB Parade to match your footage's channel distribution to the reference's grade.
