Script FAQs

What is the AI Script Generator?

add
The Script Generator takes your topic or idea and writes a full video script for you. The script is the backbone of everything that follows. It drives the visuals, voiceover, scene structure, and story arc. It's designed to get you past a blank page so you can focus on direction and content, not writing from scratch.

How do I start generating a script?

add
Go to the Content Wizard, enter your idea or choose from an idea prompt, and submit. You need at least 30 characters. ByThen generates a full script based on your input and your Content Profile, then takes you to the Script Preview page.

What is a Content Profile and how does it affect my script?

add
Your Content Profile is your creative identity in ByThen. It includes your content niche, storytelling style, language, tone, and visual aesthetic. ByThen uses it every time it generates a script or creates visuals, so everything feels consistent and aligned with your brand.

Can I bring my own script instead of generating one?

add
Yes. In the Content Wizard, switch to 'Use My Script.' Paste your script directly, describe your characters and settings, or upload a .doc or .pdf file. ByThen takes your script and generates the Key Visual and Storyboard from it without altering your copy.

Can I edit the script before or after visuals are generated?

add
Yes at both points. On the Script Preview page, you can edit and approve the script before any visuals are generated. You can also make tweaks later in the Editor Tool, though significant script changes are best made early, since the visuals are built around what's written.

Can I control the tone and style of the generated script?

add
Yes. Your Content Profile lets you define your storytelling style (documentary, educational, narrative, etc.), tone, and target audience. ByThen uses these settings to shape how scripts are written across all your projects.

Which languages are supported for script generation?

add
Multiple languages are supported. You set your preferred language in your Content Profile under the Language and Tone step, and ByThen generates scripts in that language.

Does generating a script use credits?

add
Yes, check ByThen's pricing and credits documentation for the full breakdown of what each step in the workflow costs. The credits page in the help center covers script generation, image generation, video generation, and export.

Can I regenerate a script if I don't like the first result?

add
Yes. On the Script Preview page, if the generated script doesn't feel right, you can go back, adjust your idea or content profile settings, and regenerate. You can also manually edit the script directly on the preview page rather than regenerating.
