New open-source tool Overtone cuts video captions separately for each screen aspect ratio

A developer released Overtone, an open-source captioning system that stores transcribed words with timing and speaker data once, then generates separate caption cuts optimized for different screen shapes like 16:9 and 9:16 from a single file. It ships as a CLI for creating or re-cutting caption files from subtitles, audio, or video, plus a video.js player plugin that displays the caption version matching the player's shape. The tool supports offline re-cutting of existing subtitles, and can transcribe audio using OpenAI or Azure APIs, or run fully offline via whisper.cpp and Ollama.

Developer builds Claude Code skill that narrates chess post-mortems using Stockfish

A developer created a set of Claude Code skills that convert a single chess game into a readable post-mortem, combining Stockfish engine analysis with the player's own recorded thoughts during the match. In a demonstration, Claude transcribed a French audio recording of the player's in-game reasoning via whisper.cpp, aligned it with move timestamps from the PGN, and produced a narrated video explaining specific decisions, such as bishop placement choices, verified against engine lines. All underlying files—transcript, engine analysis, annotated PGN, and storyboard—are shared in the project's example folder.
