Write to the picture
List the shots or screen actions first. Give each one a short spoken point. A voiceover line should explain what the viewer needs to know at that moment, not repeat every word already on screen.
Paste the script into TTS Lines and adjust the lines to match those moments. A scene may need two lines, and a sentence may need its own pause.
Make audio you can move
Choose a voice, generate the lines, and listen to the full sequence. If one line feels rushed, change its words or speed and generate that line again. Export a ZIP of MP3 clips when each scene may move during editing.
Put the clips in your video editor, line them up with the shots, and set music levels there. TTS Lines makes the narration; it does not edit the video or mix the soundtrack.
Check captions after the cut
You can export an SRT from TTS Lines as a starting point. If you move, trim, or stretch clips on the video timeline, adjust the captions in the video editor. Watch the finished video with sound and captions before publishing.
