Optical character recognition is the technology that extracts readable text from images or video frames. In traditional applications, OCR digitizes scanned documents or reads text from photographs. In VidNo's pipeline, OCR serves a more specialized purpose: reading the code, terminal output, and UI text visible in your screen recording frames. By running OCR across sampled frames, VidNo can determine what programming language you are writing, which files you are editing, what commands you are running in the terminal, and what error messages appear during debugging. This extracted text becomes part of the context that feeds into the script generation step. The OCR system is tuned for developer environments — it handles monospaced fonts, syntax-highlighted code, dark-themed editors, and terminal emulators with high accuracy. It can distinguish between a code editor panel, a terminal pane, and a browser preview even when they appear side by side in a split-screen layout.
