Negative Prompt<\/h3>\n
\n

low quality, low resolution, compression artifacts, blur, noise, poor anatomy, duplicate subjects, cropped, bad proportions, watermarks, logos, text overlays, incorrect lighting, oversaturated colors, underexposed, overexposed, motion artifacts, render errors, AI hallucinations, extra limbs, extra fingers, incorrect perspective, identity drift, camera jitter, frame flicker, temporal inconsistency, lip sync mismatch, motion warping, scene discontinuity, character inconsistency, object morphing, background instability, audio clipping, music distortion, robotic movement, glassy eyes, uncanny valley.<\/p>\n<\/div>\n

Expert Usage Tips<\/h3>\n
\n

Ensure the initial character description is highly specific regarding skin texture and hair style to prevent identity drift between scenes.<\/p>\n

Use a consistent reference image for the character’s face to anchor the AI model’s generation throughout the entire video sequence.<\/p>\n

Adjust the lighting keywords in each scene to match the time of day, ensuring the highlights and shadows remain physically plausible.<\/p>\n

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.<\/p>\n

Keep camera movements minimal; subtle zooms or pans are more effective for maintaining temporal consistency than complex tracking shots.<\/p>\n<\/div>\n
