Our verdict on SubVela
SubVela is a free, open-source Windows desktop application for creating subtitles locally. It uses Whisper-based speech transcription to generate timed captions with word-level timing, then supports subtitle text and timing edits, bilingual original-and-translated lines, visual styling, and video rendering with burned-in subtitles. It is aimed at creators who want an offline-first workflow without required video uploads or transcription API keys.
The pricing structure is straightforward: SubVela is free forever and open source, with no paid tiers described. Its main value is the breadth of caption work available in one desktop workflow. Users can transcribe locally, translate with local NLLB models or optional cloud providers, adjust subtitle text and timing, style typography, color, outlines, and timing, then export SRT or ASS files. FFmpeg burn-in adds a direct path from editable subtitles to video with captions rendered into the image.
The clearest fit is for Windows users who prioritize local processing and need more than basic automatic captions, especially bilingual subtitles, styling, and multiple output paths. The platform choice is also the main boundary: the application is Windows-only. Translation flexibility comes with a distinction between local models and cloud providers using user-supplied API keys, so the preferred workflow may depend on whether local model processing or external services suit the project. SubVela should appeal to creators seeking control over subtitle files and presentation; users who need a different operating system should look elsewhere.
