I built a photo and video editor that shows the maths behind every effect

Описание и применение

Браузерный редактор изображений и видео, показывающий формулы и метрики качества, использующий линейный свет, фильтр Lanczos‑3 и WebCodecs для точного экспорта.

Задача

Most editing apps hide the underlying math, making it hard for beginners to understand why an edit looks a certain way.

Результат

The editor provides transparent, math‑based editing, accurate color handling, high‑quality resizing, and lossless video export, enabling users to understand and control image processing.

Рабочий процесс

• Open the editor in a browser. Select a layer. Open the Check tab to view the equations and quality metrics. Adjust sliders; the editor recalculates in linear light. Export the image or video using the built‑in exporter. Review export error metrics if needed.

Доказательства

Most editing apps give you a slider and hide what it does. I wanted one that shows the formula, so a beginner can see why an edit looks the way it does.

It shows the equations behind the look, for example how contrast works on linear light, or how a vignette fades toward the corners.

Lanczos‑3 filter, again in linear light, instead of the browser's default.

The video exporter uses WebCodecs. It seeks each video to the exact time, draws the frame, encodes it, and writes the file, so no frames are dropped.

In my tests the numbers came out around 47 to 52 dB, which means the two look the same.
