Catch problems at
the frame level

A wrong scene direction caught at the storyboard stage costs a fraction of what it costs at full video generation. ByThen gives you a director's preview before a single frame of video is generated.

Adjust scene descriptions, regenerate individual frames, and approve the full visual arc before generating your full video. All in one workflow.

Storyboard FAQs

What is the AI Storyboard Generator?

add
The Storyboard Generator takes your approved script and Key Visual and turns them into a scene-by-scene visual plan for your video. Each scene is filled with clips, images or video segments that play alongside the voiceover narration. Think of it as the blueprint for your video before the final render.

How does the storyboard connect to my script?

add
Each scene in the storyboard maps to a section of your script. The narration text for that section becomes the voiceover, and ByThen generates the visual clips that accompany it. Scene duration is set based on the narration length.

What are scenes and clips?

add
A Scene is a section of your video that corresponds to a part of your script. A Clip is an individual image or video segment inside a scene that plays visually while the narration runs. Each scene can contain one or more clips.

How is scene duration set, and can I change it?

add
Scene duration in the Storyboard is set based on the narration length, it's not manually adjustable at this stage. If you need more time in a scene, you can increase the clip or scene duration later in the Editor Tool.

What happens if my narration is longer than the clip duration?

add
If your narration runs longer than the clips in a scene, you'll get a warning and need to add more scenes to cover the remaining narration.

Does the storyboard follow my Key Visual style throughout?

add
Yes. The Key Visual art style, color tone, environment, character direction is the foundation carried through every clip in your storyboard. Getting it right before generating the storyboard saves time and keeps your video visually consistent from start to finish.

How many scenes does a storyboard typically have?

add
It depends on the length and structure of your script. ByThen breaks the script into logical sections and assigns each one a scene. Longer, more segmented scripts produce more scenes.

What's the difference between the Storyboard and Editor Tool?

add
The Storyboard is where you plan and preview your video at a scene and clip level, you're building the blueprint. The Editor Tool is where you fine-tune the final video on a multi-track timeline: trimming, adding captions, adjusting audio, changing pacing, generating new assets, and preparing for export.
