TRV is an open source tool developed by the transformrs team and hosted on GitHub, whose core function is to transform Typst-formatted slide files with text notes into professional-grade videos through an automated process. The tool utilizes a command line mode of operation and integrates four key technology modules:
- Typst file parsing engine that recognizes
#slide[]cap (a poem)#notes[]Markers process visual content and speech text separately - Multi-platform speech synthesis interface, support for docking OpenAI/Kokoros/DeepInfra services such as TTS models
- FFmpeg video processing system for audio/video synchronization and format transcoding
- Responsive layout engine that can output 1080×1920 and other vertical screen resolutions adapted to short video platforms
Its open source features allow developers to quickly deploy through Docker images or secondary development based on Python environments, which can improve content production efficiency by 3-5 times in educational courseware production, technical demonstrations and other scenarios.
