FAQ

What is an SRT file?

An SRT (SubRip Subtitle) file is the most common format for video captions. It's a simple text file containing your script broken into numbered segments with precise timestamps. Every major video platform recognizes this format.

How accurate are the AI timestamps?

The tool uses Google's speech recognition API, which is highly accurate for clear speech. Timestamps are generated at the word level, providing very precise reference for when each word is spoken in the generated audio.

Can I upload an existing audio file?

This tool is designed to create a new AI voiceover and its timestamps from a text script. It does not currently support uploading an existing audio file for transcription.

How do I add the SRT file to YouTube?

In YouTube Studio, go to Subtitles, click Add, select Upload file, then choose your downloaded .srt file. YouTube will automatically sync it with your video.
