What is SubStudio?
SubStudio is a web-based tool that automatically generates and styles subtitles for videos. It uses AI (Whisper via Together AI) to handle transcription, alignment, and styling, offering a full-featured editor for customization. Users can upload videos or paste direct media links, and the tool processes them in minutes.
How to use SubStudio?
- Upload a video file (MP4, MOV, WEBM, MP3 up to 500MB) or paste a direct media link ending with .mp4, .mov, .webm, .mp3, or .wav. The AI automatically transcribes and aligns subtitles. Then use the editor to choose a style preset (Classic, TikTok, Modern, Box, Cinematic, Outline, Bold Center), review and edit subtitles, and export the final video.
