What the AI tools do
NibbleFlix includes AI tools that cut the time it takes to prepare content for new audiences. Treat every output as a strong first draft that a person checks before it goes live.
| TOOL | USE IT FOR |
|---|---|
| AI subtitles | Subtitles in 12 languages |
| AI dubbing | New-language voice tracks for your episodes |
| AI metadata | Draft titles, synopses and tags |
| AI trailers | Trailers of about 2 minutes cut from your episodes |
Prepare your source files
- Lock the final cut before generating anything.
- Use clean dialogue audio, with music and effects not drowning out speech.
- Write a glossary of character names, places and recurring phrases.
- Confirm your rights allow translation and dubbing in your contracts.
Review AI subtitles
- Watch at normal speed with subtitles on, the way a viewer would.
- Check names and slang against your glossary.
- Check timing so lines appear and leave with the speech.
- Check reading speed and line length on a phone screen.
- Ask a native speaker to review at least the first episodes in each language.
Review AI dubbing
A dub has to carry emotion as well as meaning. Listen to full scenes, not clips, and pay most attention to the moments your story depends on.
- Tone matches the scene, especially in arguments, reveals and cliffhangers.
- Each character keeps one voice across every episode.
- Names are pronounced the same way every time.
- The dub sits well against the music and effects.
Publish and improve
- Label the language menu clearly so viewers know which tracks are dubbed.
- Keep the original audio available alongside the dub.
- Use AI metadata for translated titles and synopses, then review them too.
- Collect viewer feedback and fix errors in the next update.
