Cómo hacer videos IA desde texto
Texto a video funciona mejor con prompts que especifican sujeto + movimiento + cámara + iluminación + estilo. Comienza con un prompt corto, mantén la duración corta e itera.
Pasos rápidos
Una lista rápida que puedes seguir en menos de un minuto.

A cinematic realism, a city alleyway in the night rain. The camera begins with a close-up of a puddle: raindrops create concentric ripples, and the red and blue reflections of neon signs are slightly distorted on the water's surface. The camera slowly rises and slides forward (a low-angle push-up), water splashing onto the front edge of the lens to create realistic wet halos and tiny droplets. A person in a dark trench coat walks past with their back to the camera; the edge of the coat is lifted by the wind, revealing the fabric's texture clearly. Their footsteps step into puddles, and the splashing water droplets shimmer like tiny silver fragments in the backlight of the streetlights. The background features slightly bokeh of neon lights and mist, with fine rain and fog floating in the air, and volumetric light beams passing through the alleyway to create visible pillars of light. The camera finally focuses on the figure's half-body silhouette from behind, neon light refracting colorful highlights on the raindrops—a tense, restrained, and cinematic atmosphere. Cinematography: 35mm cinema lens, shallow depth of field, realistic film texture, subtle grain and high dynamic range (HDR), high contrast while preserving shadow detail. Lighting: Neon main light + streetlight backlight, enhanced reflection from wet ground, highlights not overexposed. Movement: Stabilizer slider with slight handheld breathing feel. Color: Cool cyan base tone, accented with red/blue neon.

cinematic blockbuster, photoreal. Nighttime rooftop in a futuristic mega-city during light rain. Open on an extreme close-up of a gloved hand tightening a metal clasp—micro scratches, wet reflections, crisp detail. A distant siren glow pulses across the glove. Camera whips upward into a smooth stabilized dolly push as the character steps to the edge of the roof. Neon signs and traffic streams below form anamorphic bokeh; rain streaks catch volumetric light beams from a hovering drone. The character turns slightly—only a silhouette—cloak fluttering in the wind, edges rim-lit by cyan and magenta neon. A massive holographic billboard flickers behind them, casting shifting light across drifting mist. End on a heroic wide shot: the figure stands against the skyline as a drone passes close to camera, lens flare blooms, and the city breathes with depth and scale. High dynamic range, rich contrast, fine film grain, premium color grade (cool shadows, warm highlights), smooth motion, no jitter.

Consejos
- Palabras de movimiento (acercamiento, paneo, dolly lento) a menudo mejoran la sensación del video.
- Si la escena tiembla, simplifica el movimiento de cámara y acorta el prompt.
- Mantén un sujeto principal para reducir la deriva.
Preguntas frecuentes
¿Por qué mi video se ve aleatorio o inconsistente?▼
Los prompts pueden ser muy largos o conflictivos. Elimina detalles extra y mantén un solo sujeto y acción.
¿Debo usar palabras clave de cámara?▼
Sí—las palabras clave de cámara a menudo mejoran la calidad cinematográfica (primer plano, 35mm, profundidad de campo reducida).
¿Qué duración es mejor?▼
Comienza con 5 segundos. Los clips cortos tienden a verse más limpios y son más fáciles de iterar.
