{"servers":[{"url":"https://api.modellix.ai/api/v1/skywork/skyreels-t2v"}],"post":{"description":"**[Core Function]** SkyReels Text-to-Video generates a video purely from a text prompt, with no input media. **[Strengths]** Strong prompt adherence and smooth motion; supports optional audio, 480p/720p/1080p output, and a fast/std quality-speed trade-off. **[Best For]** Turning an idea or script into video, concept visualization, story beats, and social clips generated from text. **[Limitations]** Do NOT use this when the user provides an image, video, or audio input; route to Image-to-Video (skyreels-i2v), Reference-to-Video (skyreels-r2v), or the video-to-video / Omni models instead. Output is capped at 1080p and 15s per clip; fast mode currently supports only sound=false (no audio). **[Routing]** Use for text-only generation. Choose mode=fast for quicker results or mode=std for balanced quality; set resolution and aspect_ratio as needed.","operationId":"skyreelsT2VAsync","requestBody":{"content":{"application/json":{"examples":{"basic":{"summary":"Prompt only","value":{"aspect_ratio":"16:9","duration":5,"mode":"std","prompt":"A red fox running through a snowy forest at dawn, cinematic","resolution":"1080p"}}},"schema":{"description":"SkyReels text-to-video request.
