Subtitle Generation

Lyric Video Maker includes built-in AI-powered subtitle generation. It uses Whisper to either transcribe audio from scratch or align existing lyrics to the music.

Opening the Generator

In the Project Setup panel, next to the subtitle file picker, click Generate SRT. This opens the subtitle generation dialog.

INFO

You must have an audio file loaded before generating subtitles.

Generation Modes

Full Transcription

Transcribes the audio directly — no lyrics needed. The AI listens to the song and generates timed subtitle lines.

Best for when you don't have the lyrics written down, or for speech/narration.

Alignment

Aligns a provided lyrics text file against the audio. You supply a plain text file (.txt) with one lyric line per non-empty line, and the AI matches each line to the correct timing in the song.

Best for when you already have accurate lyrics and just need the timing.

Language Selection

Choose the language of the audio to improve accuracy:

English
Spanish
French
German
Italian
Portuguese
Japanese
Korean

In Full Transcription mode, an additional Auto Detect option is available that lets the AI identify the language automatically.

Generating Subtitles

Choose your mode (Full Transcription or Alignment).
If using Alignment mode, click Pick TXT to select your lyrics text file.
Select the language of the audio.
Click Generate SRT.

A progress bar shows the generation status. You can click Cancel Generation at any time.

When generation completes, the SRT file is automatically loaded into your project. The output file path is shown in the status message.

Tips

Alignment mode is more accurate when you have correct lyrics. It produces better timing than full transcription.
One line per lyric in your text file. Each non-empty line becomes a subtitle cue.
If results aren't perfect, you can edit the generated .srt file in any text editor and reload it.
