video-audio

To generate synchronized voice-over audio for video scenes, you can use a script that converts storyboard narration text into speech audio with timestamps. This process uses ElevenLabs TTS to read scenes.json narration fields and outputs per-scene or merged audio tracks aligned for synchronization.

A scenes.json narration file contains text fields for individual video scenes. When processed with a TTS engine like ElevenLabs, these text fields are converted into MP3 speech audio, matched to each scene, and merged with timestamps for video synchronization.

Yes, you need an ELEVEN_API_KEY to convert storyboard narration to speech using ElevenLabs TTS. You also need Python 3.11 or higher installed, along with a storyboard directory containing your scenes.json file with properly formatted narration fields.

Yes, you can produce a single merged narration track instead of per-scene audio. The generation script supports both output modes, allowing you to create either individual MP3 files for each scene or one combined audio file with timestamps for full video synchronization.

The best way to add timestamped text-to-speech to a video storyboard is to automate the process using a TTS script. By feeding your scenes.json file into an ElevenLabs-powered generator, you automatically receive synchronized audio tracks aligned with your scene timings.

Your scenes.json narration audio generation requires Python 3.11 or higher because the underlying TTS script depends on features and libraries available in this version. Running the script below this version may cause compatibility errors during the ElevenLabs API audio synthesis process.
