Show HN: Geneva, a Rust FFmpeg CLI alternative with HTML/CSS graphics
I built this for my own use case, and I think other people could benefit from it. It's essentially a Rust rewrite of the ffmpeg CLI command, but with a modern API and good defaults + a native HTML/CSS composition engine that's been fine tuned for speed and memory efficiency. Under the hood, it still uses the libav* codecs from ffmpeg, so it can still work on a variety of formats. Works very well with AI agents too: prompt what kind or intro/animation/graphics you need (or give it a reference), l

Version & cost evidence
Source votes: 6 votes (Nov 15, 2026 UTC; cumulative since publication); previous same-scope observation: 6 (Nov 14, 2026 UTC). These observations do not establish demand growth. Recent records to compare: “Show HN: A browser RTS where you play alongside your local agents” (Show HN, Nov 14, 2026); “Show HN: Mopup – clean up after builds and coding agents on macOS” (Show HN, Nov 14, 2026). Shared themes are navigation hints; they have not been verified as the same need or independent corroboration.
Who is affected
Identify the existing workflow this change affects before recommending an upgrade. Launch attention does not establish improvement; an API, pricing or availability change may instead create migration work.
Missing comparison points
Missing checks: old versus new behavior, affected plans and regions, availability date, compatibility, rollback path and cost under the same workload.
Migration check
Save the release or policy notice, run the same task on the old and new option, and compare outputs and the full bill. For retirement notices, verify the deadline before scheduling migration.
