Step 3: Choose Your Creation Mode

Visualix AI supports both creation workflows for Seedance:

Option A: Text-to-Video (T2V)

Type a descriptive prompt detailing the scene. For best results, follow this formula:

[Camera Movement] + [Subject & Action] + [Environment & Weather] + [Lighting & Colors] + 60fps cinematic

Example Prompt:

Cinematic low-angle tracking shot, a futuristic samurai standing in torrential rain beneath neon billboards, raindrops splashing off the blade, reflections in puddles, dramatic blue and magenta lighting, 60fps, photorealistic 8k.

Option B: Image-to-Video (I2V)

1. Click Upload Image and select a portrait, artwork, or product photo.
2. Enter a motion prompt describing what should move (e.g. 'Character blinks, smiles gently, wind blows hair, camera slowly zooms in').
3. (Optional) Upload an End Frame to control the final pose or attach a Reference Video to transfer motion.

Pro Tips for Maximum Video Quality

1. Use Specific Camera Directing Tokens: Words like 'dolly in', 'FPV drone sweep', '360 orbital tracking', and 'slow motion 60fps' give Seedance clear instructions on how the virtual camera should behave.
2. Layer Auto-Captions with One Click: Take your generated video into the Visualix AI Shorts Generator to add viral animated subtitles with word-by-word highlights.
3. One-Click 4K Upscale: If you generate in 720p 60fps on Seedance 2.5, use the built-in 4K upscaler to push the clip to cinema-grade 3840x2160 resolution in seconds.
