HunyuanVideo 1.5 for Image to Video

HunyuanVideo 1.5 Image‑to‑Video takes a single still image plus a short prompt and turns it into a 5–10 second 480p–720p clip with smooth, cinematic motion while preserving the original composition and subject.​

What HunyuanVideo 1.5 I2V is

• It is Tencent’s lightweight 8.3B‑parameter image‑to‑video model within the HunyuanVideo family, designed specifically to animate a single reference frame into a coherent sequence.​

• The model emphasizes structure preservation: characters, layout, and key details stay consistent while camera and environment move, avoiding jitter and “melty” drift.​

Core capabilities

• Single‑image animation: Takes one input image and a guiding text prompt, generating 5–8 (sometimes 10) second clips at 480p or native 720p.​

• Cinematic motion: Supports gentle push‑ins, pans, tilts, subtle subject motion (breathing, hair, clothing, water, clouds), and background parallax without collapsing structure.​

• Fast, low‑VRAM options: A distilled 480p I2V variant can run in 8–12 steps, cutting generation time by about 75% and making it practical on a single consumer GPU (like a 4090) or hosted APIs.​

Typical image‑to‑video workflow

• Provide a clean, well‑lit source frame (photo or AI image), ideally already close to your target aspect ratio (for example 1280×720).​

• Add a short motion prompt that clearly states what should move versus what should stay fixed, using spatial language like “foreground”, “background”, “center frame”.​

• Choose duration (commonly 5 or 8 seconds) and resolution (480p for previews, 720p for final), then generate and iterate, adjusting seed, duration, or motion wording one variable at a time.​

Strengths in a workflow stack

• Pairs well with high‑end image models: generate a sharp keyframe (for example with HunyuanImage 3.0 or Qwen‑Image‑2512), then hand it to HunyuanVideo 1.5 I2V to animate.​

• Has native ComfyUI support and example workflows, so it slots neatly into node‑based pipelines with clear nodes for latent creation, I2V conditioning, and decode.​

When to choose HunyuanVideo 1.5 I2V

• Short character vignettes, product hero shots, or landscape moves where the still frame is already strong and you mainly need motion.​

• Scenarios where consumer‑GPU friendliness and predictable 5–8 second 720p clips matter more than ultra‑long or 4K video.
