Video Uretimi

/v1/video/generations, LLMTR uzerinden metin promptlarini video uretim islerine donusturur. Endpoint uzun suren provider islerini baslatir, sonuc tamamlanana kadar poll eder ve video URL’lerini OpenAI uyumlu yanit yapisinda dondurur.

Alibaba HappyHorse

HappyHorse modeli Alibaba uzerinden metinden video uretir. Model public katalog aktivasyonu oncesinde 5 saniyelik 720P canli dogrulama testinden gecirilmistir.

  -H "Content-Type: application/json" \
  -d '{
    "model": "alibaba/happyhorse-1.0-t2v",
    "prompt": "A miniature city built from cardboard and bottle caps comes alive at night. A cardboard train rolls slowly by with tiny lights.",
    "duration_seconds": 5,
    "resolution": "720P",
    "aspect_ratio": "16:9",
    "max_wait_seconds": 180,
    "max_budget_usd": 0.70
  }'

Google Veo

Google Veo modelleri ayni endpoint uzerinden calisir: google/veo-3.1-generate-001, google/veo-3.1-fast-generate-001, google/veo-3.1-lite-generate-001, google/veo-3.0-generate-001, google/veo-3.0-fast-generate-001 ve google/veo-2.0-generate-001. Veo 3.x ciktilari sesli uretilir.

curl "$LLMTR_BASE_URL/v1/video/generations" \
  -H "Authorization: Bearer llmtr-your_key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "google/veo-3.1-fast-generate-001",
    "prompt": "A cinematic drone shot over Cappadocia at sunrise",
    "duration_seconds": 8,
    "aspect_ratio": "16:9",
    "resolution": "720p",
    "max_wait_seconds": 180,
    "max_budget_usd": 1.00
  }'

Gorsel referans ile video (image-to-video)

Veo modelleri image_url alaninda base64 data URL olarak verilen bir referans karesinden video uretebilir. Remote URL desteklenmez; data:image/...;base64,... bicimi zorunludur ve remote URL gonderilirse 400 unsupported_input doner.

curl "$LLMTR_BASE_URL/v1/video/generations" \
  -H "Authorization: Bearer llmtr-your_key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "google/veo-3.1-fast-generate-001",
    "prompt": "The person smiles and looks around, subtle camera push-in.",
    "image_url": "data:image/png;base64,iVBORw0KGgo...",
    "duration_seconds": 4,
    "resolution": "720p",
    "max_wait_seconds": 180
  }'

Veo yanitlarinda video, data[].b64_json alaninda base64 MP4 olarak doner; url alani bu modellerde null olur.

xAI Grok Imagine

xai/grok-imagine-video metin promptundan video uretir. xai/grok-imagine-video-1.5 ise image-to-video calisir: bir baslangic karesi zorunludur ve prompt hareketi tanimlar. Grok Imagine Video 1.5 ses efektleri, ambiyans ve konusmayi ayni geçişte uretir. Desteklenen sure 1-15 saniye; cozunurlukler 480p, 720p ve 1080p (1080p yalniz image-to-video).

Baslangic karesi image_url alaninda base64 data URL olarak gonderilir. Model yalniz image-to-video oldugu icin image_url olmadan gonderilen istek 400 invalid_request doner; metinden videoya grok-imagine-video modeline image_url gonderilirse 400 unsupported_input doner.

curl "$LLMTR_BASE_URL/v1/video/generations" \
  -H "Authorization: Bearer llmtr-your_key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "xai/grok-imagine-video-1.5",
    "prompt": "Yavas sinematik push-in, korlar dagiliyor, hafif kamera hareketi",
    "image_url": "data:image/png;base64,iVBORw0KGgo...",
    "duration_seconds": 6,
    "resolution": "720p",
    "aspect_ratio": "16:9",
    "max_wait_seconds": 180,
    "max_budget_usd": 1.00
  }'

xAI yanitlarinda video data[].url alaninda barindirilan MP4 olarak doner. Faturalama, mevcutsa gercek provider maliyetini esas alir; asagidaki saniye bazli oran rezervasyon ve fallback tahminidir.
