Everything you need.

A complete toolkit for pixel-level video control, from resolution math to live output.

📐

Resolution Calculator

12 presets from SD to 8K, custom resolution input, aspect ratio, megapixel count, and raw bandwidth calculations — bitrate, frame size, per minute, per hour.

Canvas Overlays

Rule of thirds, golden ratio, center point, crosshair, corner marks, diagonals, adjustable guides, safe zone, pixel grid, and a pixel-accurate ruler with center-origin mode.

🎬

Timing & Sync

All standard frame rates including 23.976 and 59.94. Refresh rate matching with FPS/Hz mismatch warnings. Timecode overlay with frame-accurate counting.

📷

Video Source Overlay

Feed live camera or screen share directly into the canvas. Adjustable opacity, contain/cover/stretch fit modes. Perfect for comparing against overlays in real time.

🖥

Output Pipeline

Fullscreen, pop-out window at native resolution for HDMI output, MediaStream capture for OBS/vMix, and NDI distribution via obs-ndi plugin.

📊

Data Export

JSON export with all resolution data, timing, bandwidth, overlay state, and pixel mapping coordinates. Mask export as pixel-perfect PNG at source resolution.

Projection masking.

Draw precise masks for projection mapping directly in the browser. Polygon, rectangle, and freehand brush tools with soft edge control — export pixel-perfect PNGs ready for Resolume, MadMapper, or any projection software.

Polygon drawing with live preview lines and auto-close
Brush tool with adjustable size and hardness — soft feathered edges for organic shapes
Invert mask to mask outside shapes — works with both polygons and brush
Pixel coordinate readout at cursor, clamped to edge pixels in the gutter zone
Export as PNG at source resolution or screenshot with ruler overlay

From browser to projector.

Multiple output paths — choose what fits your production setup.
