How to Generate Horizontal AI Videos for YouTube
Start with a clear YouTube format: a narrated explainer, a travel sequence, a product story, or a cinematic short. Plan for a 16:9 frame, the standard horizontal shape used by most YouTube long-form videos. Write a brief outline with a beginning, key beats, and ending, then assign each beat a visual scene.
Use YB Video from YB.Digital at https://yb.digital/video to generate scenes for your sequence. Describe the subject, setting, action, camera movement, lighting, and mood in each prompt. A scene brief such as “a lone cyclist crossing a misty coastal road at sunrise, wide establishing shot, slow camera push” gives the generator concrete visual direction without prescribing details you do not need.
Build continuity by keeping recurring details consistent across prompts. Specify the same character appearance, wardrobe, location, and color palette, and vary framing to support the story: use wide shots to establish place, medium shots for interaction, and close-ups for meaningful details. Treat each generated clip as a separate storyboard panel that you can arrange around narration or dialogue.
| Production step | What you define | Purpose |
|---|---|---|
| Outline | Story beats and narration | Sets the sequence |
| Prompt | Subject, action, setting, camera | Directs each scene |
| Generate | Horizontal visual clips | Creates scene material |
| Edit | Clip order, sound, transitions | Shapes the finished video |
Generate clips with editing in mind. Keep prompts focused on one main action, and create separate shots when the scene needs a change in angle or setting. Review each result for composition, motion, and consistency before placing it on the timeline. In your editor, trim pauses, arrange scenes to match the script, and add voice-over, music, captions, and sound effects.
Before exporting, check that titles and important action stay within the frame’s safe area, since interface elements and playback on different screens can obscure edges. Set the export to a horizontal 16:9 resolution supported by your editing software, and watch the full video for abrupt cuts, mismatched audio, or visual jumps. Prepare a descriptive YouTube title, thumbnail, and captions alongside the final file.
- Use a shot list to track scenes against narration.
- Keep generated text out of scenes when you will add readable titles in the editor.
- Save prompt versions beside the clips they produced.
- Use room tone or a short audio bed to soften scene changes.
