Roteamento de modos
happyhorse-1.1 é a entrada unificada para Text-to-Video / Image-to-Video / Reference-Image-to-Video. O backend determina automaticamente o modo com base nos parâmetros recebidos. Todos os modos são cobrados pela mesma regra (apenas resolução × segundos):
| Campos passados | Roteia para | Descrição do modo |
|---|---|---|
Apenas prompt | Text-to-Video (T2V) | Gera vídeo puramente a partir de texto |
prompt + first_frame_image | Image-to-Video (I2V) | Anima a partir de uma imagem do primeiro quadro |
prompt + image_urls (1–9 imagens) | Reference-Image-to-Video (R2V) | Gera uma nova cena a partir de imagens de referência |
first_frame_image > image_urls > apenas prompt.
Regras de exclusão mútua: os dois campos de mídia (first_frame_image / image_urls) são mutuamente exclusivos. Passar dois campos mutuamente exclusivos ao mesmo tempo retorna 400 mixed_media_not_allowed.

true: adiciona marca d’águafalse: sem marca d’água (padrão)
integer
Seed aleatório usado para controlar a aleatoriedade do conteúdo geradoIntervalo de valores:
[0, 2147483647]. Se omitido, um seed aleatório é usado.- Para requisições idênticas, o modelo gera resultados diferentes ao receber valores de seed diferentes (por exemplo, omitindo o seed)
- Para requisições idênticas, o modelo gera resultados semelhantes ao receber o mesmo valor de seed, mas a consistência exata não é garantida

Casos de uso
Caso 1: Texto para vídeo T2V (Requisição mais simples)
{
"model": "happyhorse-1.1",
"prompt": "A little girl walking down the road, cinematic feel"
}
Caso 2: Texto para vídeo T2V (Parâmetros completos)
{
"model": "happyhorse-1.1",
"prompt": "A coastal road at sunset, slow-motion camera push-in, cinematic feel",
"resolution": "1080P",
"size": "16:9",
"duration": 8,
"seed": 42
}
Caso 3: Imagem para vídeo I2V (first_frame_image)
{
"model": "happyhorse-1.1",
"prompt": "Bring the scene in the image to life",
"first_frame_image": "https://example.com/first_frame.png",
"resolution": "1080P",
"duration": 5
}
Caso 4: Referência-Imagem para vídeo R2V (múltiplas referências)
{
"model": "happyhorse-1.1",
"prompt": "The protagonist from image 1 runs through the scene from image 2, then picks up the prop from image 3. Keep a 3D cartoon style with smooth motion.",
"image_urls": [
"https://example.com/img_01.jpg",
"https://example.com/img_02.png",
"https://example.com/img_03.jpeg"
],
"resolution": "1080P",
"size": "16:9",
"duration": 5
}
Caso 5: 720P para economizar custo
{
"model": "happyhorse-1.1",
"prompt": "Waves crashing on the beach at sunset",
"resolution": "720P",
"size": "16:9",
"duration": 5
}
Guia de seleção de modo
| Requisito | Abordagem recomendada |
|---|---|
| Gerar vídeo apenas a partir de texto | Passe apenas prompt (T2V) |
| Fazer uma imagem “ganhar vida” (usar como primeiro quadro) | Passe first_frame_image (I2V) |
| Gerar uma nova cena a partir de um conjunto de imagens de referência | Passe image_urls (1–9, R2V) |
| Economizar custo | Use resolution: "720P" |
Dicas de uso
- Lógica de entrada unificada: os campos de entrada decidem o modo. Note que os dois campos de mídia (
first_frame_image/image_urls) são mutuamente exclusivos sizeefetivo apenas em T2V/R2V: no modo I2V,sizeé ignorado — a proporção de saída é determinada pela mídia de entrada- Duração: 5–10 segundos é o ponto ideal. Muito curto causa movimento truncado; muito longo aumenta significativamente o tempo de processamento upstream
- Qualidade da imagem do primeiro quadro: clara, bem composta, sujeito centralizado — melhora significativamente a saída I2V
- Escrita do prompt: descreva movimento / câmera / atmosfera (por exemplo, “slow push-in, cinematic, warm tones”) para obter melhores resultados do que descrições puramente estáticas de cena
