Como Usar o Hailuo AI Text-to-Video em 2025: Guia Completo para Iniciantes
Introdução: O que é um Prompt?
O prompt é a chave para o mundo da IA generativa, construído a partir da sua inspiração e criatividade.
Seja você um iniciante em IA ou um veterano que já domina o uso de IA para aumentar a produtividade, é possível dominar a habilidade de escrever prompts através de uma estrutura clara e formas flexíveis de expressão. A visão de “uma pessoa + uma IA = uma equipe profissional” está prestes a se tornar realidade.
Para melhorar a qualidade dos resultados em vídeo, desenvolvemos duas fórmulas de prompt para seu uso:
1. Fórmula Básica de Prompt
A Fórmula Básica de Prompt é ideal para quem não tem certeza sobre o vídeo exato que deseja criar ou para quem busca usar o Hailuo AI como fonte de inspiração. Esse tipo de prompt oferece uma variedade de ideias visuais mais criativas.
❤️Fórmula Básica = Assunto Principal + Cena + Movimento
Assunto Principal: A mensagem central do vídeo pode ser uma pessoa, um animal, um objeto ou até mesmo algo imaginário que não existe.
Cena: Descreve o ambiente do vídeo, como uma biblioteca, uma cafeteria... ou até um espaço fictício fantástico.
Movimento: Descreve o estado de movimento do objeto principal no vídeo, como imobilidade, deslocamento, ou transformações no ambiente.
Exemplos:
Um filhote de cachorro corre no parque.
Uma mulher com guarda-chuva caminha em uma rua chuvosa.
Um riacho flui suavemente em um vale.
2. Fórmula de Prompt Preciso
A Fórmula de Prompt Preciso é para usuários que exigem movimentos avançados de câmera ou apresentações cinematográficas profissionais. Prompts detalhados melhoram a qualidade visual do resultado.
Fórmula Preciso = Assunto Principal + Cena + Movimento + Movimento de Câmera + Atmosfera Estética
Movimento de Câmera: Use termos comuns como tracking, zoom, panorâmica ou câmera manual para controlar a apresentação final.
Atmosfera Estética: Descreva o estilo visual e a atmosfera para obter resultados melhores.
Exemplos:
Um casal sentado em um banco de parque conversando. A câmera mantém um plano fixo do casal. A tonalidade da imagem é quente, com atmosfera aconchegante.
Um cordeiro pastando em um campo. A câmera avança lentamente em direção ao cordeiro. A tonalidade é natural e realista.
Um homem de terno come macarrão em uma lanchonete. A câmera se afasta gradualmente, mostrando o ambiente barulhento. Tonalidade natural.
3. Dicas para Usar as Fórmulas de Prompt
Não existe certo ou errado na escrita de prompts, mas dois princípios são essenciais:
- Quanto mais preciso o prompt, mais preciso o resultado.
- Quanto mais detalhado, melhor o efeito geral.
Intermediário: Como Obter o Melhor Desempenho
Controle Preciso da Câmera
O Hailuo AI responde eficientemente a movimentos de câmera, oferecendo resultados profissionais.
- Adicione detalhes ao movimento da câmera
Exemplo: “A câmera desce” pode ser otimizado para:
“A câmera desce lentamente e gira para a direita durante o movimento.”
- Descreva mudanças durante o movimento
Exemplo: “A câmera filma a girafa de baixo para cima” torna-se:
“A câmera inicia com um close das patas da girafa, sobe para capturar o corpo e para no rosto, destacando sua expressão.”
- Limite o movimento a 5-6 segundos: evite planos complexos que causem falhas.

Prompt 1
The camera begins with an overhead shot of a mysterious forest clearing, with a female warrior in armor standing alone in the center of the clearing. Her armor shimmers with a cold silver light in the moonlight, and the trees around her cast dappled shadows. The camera begins to slowly descend and hover around her, as the perspective changes, the longsword in her hand can be seen trembling slightly, with undried blood remaining on the blade, the camera continues to wrap around, sliding from side to side, gradually drawing in closer to capture the side of her determined face. Her slightly clenched lower lip could be seen, and a few loose strands of hair on her face were soaked in sweat and plastered to her forehead. As the camera circled around to her front, the image became tighter, the focus gradually coming to rest on her face. By now, the forest in the background has blurred into a dark shadow. The camera eventually stops at a close-up of her front, focusing on her sharp eyes. The moonlight hits her face, outlining every detail of her face.

In a dimly lit room, a young boy is captured in close-up, his eyes glued to the glowing screen of a game console. The camera is slightly above the horizon, focusing on his concentrated expression as his fingers deftly manipulate the controller. Suddenly, the mood changes as the figure of a game character suddenly appears and breaks through the screen. The camera has a shallow depth of field and pans smoothly between the boy and the now three-dimensional figure, blurring the edges of the console and the wall behind it, which is plastered with posters for various games. The boy interacts with the character in surprise, his movements reflecting the excitement and disbelief of the moment. The characters are vivid and detailed, jumping and dancing around the room and playing with the boy. The camera captures the fantastical scene with dynamic angles and fluid movements, enhancing the sense of wonder and movement through a skillful combination of slow motion and fast editing. Subtle changes in lighting enhance the realism of the characters' movements, with shadows and highlights interplaying on the boy and the characters.
