Wan 2.1 V2V 480P LoRA Ultra Fast

Wan 2.1 V2V 480p LoRA Ultra Fast — wavespeed-ai/wan-2.1/v2v-480p-lora-ultra-fast

Wan 2.1 V2V 480p LoRA Ultra Fast is a speed-optimized video-to-video model for prompt-guided edits while preserving the original motion and timing of an input video. Upload a source video, describe what should change, and tune strength to control how closely the output follows the original footage. It supports up to 3 LoRAs to enforce a consistent style, character look, or branded aesthetic—now with lower latency for rapid iteration.

Key capabilities

• Ultra-fast video-to-video transformation anchored to an input video (480p output)
• Prompt-guided edits while keeping motion continuity and pacing
• Strength control to balance preservation vs. transformation
• LoRA support (up to 3) for stable style/identity steering
• Fine control over motion behavior via flow_shift

Use cases

• Rapid V2V restyling for social clips and creative iteration
• Apply a consistent “house style” across multiple clips using LoRAs
• Lighting/mood changes (cinematic grade, neon, golden hour) without re-animating motion
• Brand-safe refresh: keep composition and timing, update textures/colors/details
• Quick A/B testing by changing prompts, LoRAs, or seed

Pricing

Inputs

• video (required): source video to transform
• prompt (required): what to change and how the result should look
• negative_prompt (optional): what to avoid (artifacts, jitter, unwanted elements)
• loras (optional): up to 3 LoRA items for style/identity steering

Parameters

• num_inference_steps: sampling steps
• duration: output duration (seconds)
• strength: how strongly to transform the input video (lower = preserve more; higher = change more)
• guidance_scale: prompt adherence strength
• flow_shift: motion/flow behavior tuning
• seed: random seed (-1 for random; fixed for reproducible results)

LoRA (up to 3 items):

• loras: list of LoRA entries (max 3)

  • path: owner/model-name or a direct .safetensors URL
  • scale: LoRA strength

Prompting guide (V2V)

Write prompts that explicitly separate preservation from transformation:

Template: Keep the same camera motion and timing from the input video. Change [style/lighting/environment]. Keep faces natural and consistent. Avoid flicker and warping.

Example prompts

• Keep the original motion and composition. Apply a candid, cinematic look with warm sunlight, soft depth of field, and natural skin texture.
• Preserve timing and camera movement. Restyle into a clean anime look with consistent shading and no flicker.
• Keep the same scene and people. Change the color grade to sunset golden hour, add subtle lens flare, maintain realistic shadows.
