Seedance 2.0 Fast API-Referenz

Mit einem einzigen PopNow-API-Schlüssel rufst du Seedance 2.0 Fast aus deinem eigenen Code auf. Hier findest du die Modell-IDs, jedes Eingabefeld, die Kosten pro Anfrage in Credits und eine Anfrage, die du direkt ins Terminal kopieren kannst.

Die Parameterbeschreibungen stammen aus dem Eingabeschema des Modells und sind nur auf Englisch verfügbar.

Auf einen Blick

Hersteller: ByteDance
Ergebnis: Video
Ab: 3.38 Credits pro Sekunde Ergebnis ($0.0338)
Typische Dauer: etwa 138 s
Modell-IDs: bytedance/seedance-2.0-fast/text-to-video
bytedance/seedance-2.0-fast/image-to-video
bytedance/seedance-2.0-fast/reference-to-video

1 Credit = 0,01 $. Bei Annahme reserviert ein Task den höchstmöglichen Betrag und rechnet am Ende den tatsächlichen Verbrauch ab, auf ganze Credits aufgerundet; der Rest wird freigegeben. Fehlgeschlagene Tasks kosten nichts. Den genauen Betrag vorab liefert POST /api/v1/jobs/quote.

`generate_audio`Optional	`boolean`	`true`	—	Request synchronised output audio.
`enable_web_search`Optional	`boolean`	`false`	—	Let the model search the web for information related to the prompt before rendering. Requests with it on are billed at the web-search rate.

`return_last_frame`Optional	`boolean`	`false`	—	Also return the clip’s final frame as a separate image.
`bitrate_mode`Optional	`string`	`standard`	standard, high	Encoding bitrate of the delivered file: standard, or high for crisper detail and a larger file.

Parameter

Feld	Typ	Standardwert	Erlaubt	Bedeutung
`video_url`Pflicht	`string (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.
`prompt`Optional	`string`	—	—	What happens next: the action that follows, the camera move and the sound. Optional.
`last_image_url`Optional	`string`	—	—	Optional closing image: the new segment lands on this picture. Leave it out and the model decides how the shot ends.
`resolution`Optional	`string`	`720p`	480p, 720p	Resolution of the new segment. Match your source clip.
`duration_seconds`Optional	`integer`	`5`	-1, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15	Length 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_audio`Optional	`boolean`	`true`	—	Generate a native soundtrack for the new segment. The source keeps its own sound either way.
`seed`Optional	`integer`	—	0 bis 2147483647	Random seed. Omit to let the model pick one.
`bitrate_mode`Optional	`string`	`standard`	standard, high	Encoding bitrate of the delivered file: standard, or high for crisper detail and a larger file.
`watermark`Optional	`boolean`	`false`	—	Add the model’s visible "AI generated" watermark to the video.
