# Opprett en Kling Motion Control-oppgave
> Opprett en Kling Motion Control-oppgave fra et karakterbilde og en referansevideo for bevegelse med den kompatible CometAPI-ruten.
Bruk dette endepunktet til å opprette en Motion Control-oppgave fra et karakterbilde og en
referansevideo.
Denne siden beskriver den kompatible Motion Control-ruten. Kling Video 3.0
Motion Control bruker en separat API-kontrakt.
## Nødvendige medier
`image_url` aksepterer en offentlig URL eller en rå Base64-streng.
* Bruk et JPG-, JPEG- eller PNG-bilde som er på maksimalt 10 MB.
* Angi hver bildedimensjon til mellom 300 og 65 536 piksler.
* Bruk et størrelsesforhold mellom 1:2,5 og 2,5:1.
* Send Base64 som den rå kodede strengen uten et
`data:image/...;base64,` prefiks.
* Vis én karakter uten hindringer, med kroppsutsnitt som samsvarer med bevegelses
referansen.
`video_url` aksepterer en offentlig MP4- eller MOV-URL.
* Bruk en video som er på maksimalt 100 MB.
* Angi den korte siden til minst 340 piksler.
* Angi den lange siden til maksimalt 3850 piksler.
* Bruk en sammenhengende opptak med én synlig karakter.
* Unngå klipp, kameraendringer og svært raske bevegelser.
Følg varighetsgrensene, og kontroller den nestede endelige `task_status`. En
ytre HTTP 200 eller responsen `code: 0` bekrefter spørringsresponsen, ikke et
vellykket genereringsresultat.
## Angi orienteringsverdien
`character_orientation` er obligatorisk og godtar `image` eller `video`.
| Verdi | Referansevideoens varighet |
| ------- | -------------------------- |
| `image` | 3–10 sekunder |
| `video` | 3–30 sekunder |
Hvis du bruker `element_list`, angir du `character_orientation` til `video`.
## Velg modell og modus
Den kompatible ruten godtar `kling-v2-6` og `kling-v3`. Begge modellverdiene
godtar begge modusverdiene:
| Modell | `std` | `pro` |
| ------------ | -------- | -------- |
| `kling-v2-6` | Godkjent | Godkjent |
| `kling-v3` | Godkjent | Godkjent |
Hvis du utelater `model_name`, bruker forespørselen `kling-v2-6`. Hvis du utelater `mode`,
bruker forespørselen `std`. Verdien `kling-v3` beholder den kompatible forespørselsstrukturen
som beskrives på denne siden; den velger ikke den separate kontrakten for Kling 3.0 med baneversjon
.
Den kompatible kontrakten garanterer ikke en fast utdataoppløsning. Kontroller
hver returnerte video hvis applikasjonen krever bestemte dimensjoner.
`keep_original_sound` aksepterer `yes` eller `no`. Hvis du utelater dette feltet, bruker
forespørselen `yes`.
## Oppgaveflyt
Send kildebildet, referansevideoen og orienteringsverdien. Velg en
modell, modus og lydverdi, eller bruk de dokumenterte standardverdiene. Lagre den
returnerte `task_id`.
Bruk [Hent en Kling-oppgave](./individual-queries) med den returnerte `task_id`.
Fortsett til statusen er `succeed` eller `failed`.
Last ned og lagre resultatet raskt. Klings kompatible API-
dokumentasjon oppgir at genererte videoer slettes etter 30 dager. Ikke
stol på at den returnerte URL-en forblir tilgjengelig i hele 30-dagersperioden.
## Valgfrie felt
| Felt | Struktur | Begrensning |
| ------------------ | ---------------------------------------------------- | ----------------------------------------------------------------------------------------------------------- |
| `prompt` | Streng, maksimalt 2500 tegn | Valgfritt tekstfelt i den kompatible forespørselsstrukturen. |
| `callback_url` | URI-streng eller tom streng | Utelat feltet eller bruk en tom streng når ingen callback-URI er konfigurert. |
| `external_task_id` | Streng som er unik for kontoen din | Kobler oppgaven til applikasjonen din. Den erstatter ikke den returnerte `task_id` for CometAPI-spørringer. |
| `element_list` | Array med maksimalt ett `{"element_id": 123}`-objekt | Kombiner dette feltet bare med `character_orientation: "video"`. |
| `watermark_info` | `{"enabled": boolean}` | Den kompatible vannmerkestrukturen inneholder bare den boolske verdien `enabled`. |
## Callback-struktur
Legacy-callback-skjemaet har følgende struktur:
```json theme={null}
{
"task_id": "",
"task_status": "succeed",
"task_status_msg": "",
"created_at": 1785398400000,
"updated_at": 1785398460000,
"final_unit_deduction": "",
"final_balance_deduction": {
"quota": "",
"list_price": ""
},
"task_info": {
"external_task_id": ""
},
"task_result": {
"videos": [
{
"id": "",
"url": "https://media.example.com/.mp4",
"duration": "6.4"
}
]
}
}
```
Callback-statusen kan være `submitted`, `processing`, `succeed` eller `failed`.
Endelige resultatfelt finnes bare når de returneres for den endelige tilstanden.
## Resultatfelt
| Felt | Type | Beskrivelse |
| ------------------------------------ | ----------------------------------------- | -------------------------------------------------------------- |
| `task_result.videos[].id` | Streng | ID for generert video. |
| `task_result.videos[].url` | URI-streng | Leverings-URL for generert video. |
| `task_result.videos[].watermark_url` | URI-streng | Leverings-URL for vannmerket video når oppgaven returnerer en. |
| `task_result.videos[].duration` | Streng | Varighet for generert video i sekunder. |
| `final_unit_deduction` | Streng | Endelig verdi for enhetsfradrag returnert med oppgaven. |
| `final_balance_deduction` | `{"quota": string, "list_price": string}` | Endelige verdier for balansefradrag returnert med oppgaven. |
Oppgavestatusen er `submitted`, `processing`, `succeed` eller `failed`.
