case study / shipped
Monosect
Native desktop video splitter. Hits Telegram's 2 GB limit on the first try.

Problem
Creators sharing long videos to Telegram spend time manually slicing and re-encoding around the 2 GB limit, often overshooting and having to retry.
Approach
GOP-aware cutting guarantees keyframe boundaries. A bitrate-informed size engine pre-computes segment lengths so the first pass lands within tolerance.
Outcome
v1.1.0 publicly shipped. Turned a repetitive multi-attempt task into a single-pass workflow.
Key decisions
Conservative keyframe selection: always pick the earlier boundary to avoid overshooting.
Static linking: one EXE, no redistributable dependencies, drag-and-drop install.
GitHub Actions releases: tag push → portable ZIP + EXE with SHA256 checksum.
