Expert Usage Tips
Ensure the initial character description is highly specific regarding skin texture and hair style to prevent identity drift between scenes.
Use a consistent reference image for the character’s face to anchor the AI model’s generation throughout the entire video sequence.
Adjust the lighting keywords in each scene to match the time of day, ensuring the highlights and shadows remain physically plausible.
For best results, use a high-quality voiceover file as the primary input for lip-sync tools rather than relying on text-to-speech alone.
Keep camera movements minimal; subtle zooms or pans are more effective for maintaining temporal consistency than complex tracking shots.
