Referência da API do Seedance 2.0 Fast

Seedance 2.0 mais rápido, com som em 720p

Com uma única chave de API da PopNow você chama o Seedance 2.0 Fast direto do seu código. Aqui estão os IDs de modelo a enviar, cada campo de entrada aceito, quantos créditos custa cada requisição e um exemplo que você cola no terminal e roda.

As descrições dos parâmetros vêm do schema de entrada do modelo e estão disponíveis só em inglês.

Resumo

Desenvolvedor
ByteDance
Resultado

A partir de
3.38 créditos por segundo gerado ($0.0338)
Tempo médio
cerca de 138 s

1 crédito = US$ 0,01. Ao ser aceita, a tarefa reserva o valor máximo possível e, no fim, cobra o uso real, arredondado para cima em créditos inteiros; o restante é liberado. Tarefas que falham não são cobradas. Para saber o valor exato antes de rodar, chame POST /api/v1/jobs/quote.

Parâmetros

CampoTipoPadrãoValores aceitosPara que serve
video_urlObrigatóriostring (uri)——The clip to continue: MP4, MOV or WebM, up to 60 seconds. Its last frame opens the new segment, and the result is your clip with the new segment joined on.
promptOpcionalstring——What happens next: the action that follows, the camera move and the sound. Optional.
last_image_urlOpcionalstring——Optional closing image: the new segment lands on this picture. Leave it out and the model decides how the shot ends.
resolutionOpcionalstring720p480p, 720pResolution of the new segment. Match your source clip.
duration_secondsOpcionalinteger5-1, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15Length of the new segment in seconds. This is the billed quantity; the source clip is added on top and is not billed. Pass -1 for smart duration: the model picks the length itself.
generate_audioOpcionalbooleantrue—Generate a native soundtrack for the new segment. The source keeps its own sound either way.
seedOpcionalinteger—de 0 a 2147483647Random seed. Omit to let the model pick one.
bitrate_modeOpcionalstringstandardstandard, highEncoding bitrate of the delivered file: standard, or high for crisper detail and a larger file.
