About ViralCutter
ViralCutter is an open-source repository that converts long YouTube videos into short vertical clips for TikTok, Instagram Reels and YouTube Shorts. It includes AI-assisted segment selection, WhisperX-based transcription, word-level subtitles, 9:16 auto-crop with split-screen options, and subtitle translation.
It is described as running on the user's own computer through a Gradio-based WebUI with a project gallery and subtitle editor. Use requires installing dependencies such as Python, FFmpeg and build tools, with an NVIDIA GPU recommended, and a choice between local models or external services such as Gemini or GPT-4, which would process data outside the local machine.
