Translation tools include automatic translation and local engines, while OCR support includes Tesseract, PaddleOCR, and cloud engines. Video tools handle burn-in, re-encoding, cutting, and remuxing. For proofreading, it can use llama.cpp, Ollama, or an OpenAI-compatible endpoint. The seconv command-line tool supports headless and bulk conversion, and documentation covers creating and installing plugins. The open-source project is maintained at SubtitleEdit and hosted on GitHub Pages. Documentation, a FAQ, and contributing guidance are available. It is free, with no stated free-tier limits.

It supports offline preparation and export, live or semi-live subtitling and captioning, and online project management. Listed formats include STL/EBU, PAC, SRT, SUB, TTML, XML, TXT and WebVTT. Quality checks can flag overlapping cues, duration or reading-speed problems, line limits and typographic errors.

The localization product line integrates with Avid iNews and Octopus newsroom systems and lists machine-translation connections to Microsoft, Google, DeepL and LibreTranslate. Exports include MOV with alpha and subtitle formats such as SRT, TTML, SCC and MCC for use with video editing software. The product is designed for Windows; its FAQ describes running it on Mac through compatibility software and on Linux through Wine. Pricing is on request, with a free trial available. The demo cannot save in SubtitleNEXT format, limits export or burn-in to 20 subtitles, adds a watermark and blocks copying subtitles to other programs.
