She gently taps the side of the sample container once. The creature flashes back with the exact same rhythm. She pauses, taps twice, and it responds twice. Her expression changes from scientific curiosity to amazement. The camera begins close on her hands and the creature, then slowly pushes toward her reaction. Intelligent-life discovery, subtle sci-fi tension, realistic underwater atmosphere.
HeyGen Video 1.0 Reference-to-Video creates short videos using images and videos as visual references. Add a prompt to describe the scene, motion, camera direction, dialogue, and sound, with optional audio references for additional guidance.

time.sleep(2)Video 1.0 Reference To Video is a Heygen model for reference-guided video generation, exposed as a REST API on WaveSpeedAI. HeyGen Video 1.0 Reference-to-Video generates high-quality AI videos guided by image, video, and optional audio references, with prompt-controlled scenes and output up to 2K for character consistency, product videos, social content, marketing creatives, and production workflows. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.
POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID. Poll the result endpoint starting around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. The playground generates Python, JavaScript, and cURL examples for submitting requests and polling results. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/heygen/heygen-video-1.0-reference-to-video.
Video 1.0 Reference To Video starts at $0.07 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.
Key inputs: `prompt`, `aspect_ratio`, `resolution`, `duration`, `seed`, `reference_images`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/heygen/heygen-video-1.0-reference-to-video.
Sign up for a free WaveSpeedAI account to claim starter credits, copy your API key from /accesskey, then call the endpoint shown in the API tab of the playground. The playground also auto-generates a code sample in Python, JavaScript, or cURL for the parameters you've set.
Commercial usage rights depend on the model's license, set by its provider (Heygen). Check the provider's applicable terms and WaveSpeedAI's Terms of Service before commercial use.
