Wan 2.7 -- Gere um vídeo a partir de texto
Enviar tarefa de texto para vídeo (wan2.7)
Gere vídeos de até 15 segundos em 1080P a partir de prompts de texto, com sincronização de áudio opcional e narrativa multi-shot.
Mudanças de wan2.6
- Controle de resolução: Definir
resolution(720P/1080P) +ratio(16:9, 9:16, etc.) em vez do pixel exatosize. - Prompts mais longos: até 5.000 caracteres (era 1.500).
- Prompt negativo movido: Agora em
input.negative_promptem vez deparameters.negative_prompt. - ** Não
shot_typeparâmetro **: Descreva as fotos diretamente no texto do prompt. - Marca d'água desativada por padrão:
watermarko padrão éfalse(eratrue).
