Introduction
Wan 2.2 LoRA animates an opening frame with Alibaba's Wan 2.2 image-to-video model and lets you load your own trained LoRA weights on top of it to steer style, character or motion. The frame and a motion prompt are required. LoRAs go into three optional slots with up to three entries each, and every entry is a direct URL to a weights file of up to 1 GB plus a strength from 0 to 4. Clips are exactly 5 or 8 seconds long, at 480p or 720p.
Key features
Three slots mapped to two denoising passes
Wan 2.2 denoises in two passes. high_noise_loras attaches weights to the high-noise expert, where composition and motion are decided; low_noise_loras attaches them to the low-noise expert, where detail and texture resolve; loras applies them to both. A line-art or grain treatment usually belongs in the low-noise slot, and a camera or movement style in the high-noise one.
Separate strengths for camera style and render style
Because the slots attach to different passes, a motion LoRA and a texture LoRA can share one request with their own scales, and you can turn one up and the other down instead of balancing a single blended weight. Inside a single slot, stacked LoRAs blend rather than layer, which is why adding them one at a time is the safer order.
Weights stay on your hosting
Each file is fetched from the URL you supply for the duration of the run, and nothing is stored on the platform. Direct download links work, as do Civitai model pages or download links and Hugging Face blob or resolve links, which are resolved to the file automatically. Other share pages and anything behind a login fail the fetch, so weights that must stay private belong behind a signed link.
The base model when the slots are empty
All three arrays default to empty. A request without LoRAs returns the base Wan 2.2 image-to-video result for the same frame and prompt, which is the reference that any strength sweep is measured against.

Pricing
Prices are in credits, the same credits you use on the website (1 credit = $0.01). The hold is taken when the task is accepted and settled to the actual charge when it finishes; failed tasks are refunded.
| Option | Credits per second | ≈ USD |
|---|---|---|
| resolution 480p | 3.6 | $0.036 |
| resolution 720p | 7.2 | $0.072 |
For an exact number before you run, send the same body to POST /jobs/quote.
Use cases
Camera style kept apart from render style
Put a motion or camera LoRA in the high-noise slot and a texture LoRA in the low-noise slot of the same request. When the movement is right but the texture is too heavy, lower only the low-noise scale and rerun with the same frame, prompt and seed.
Finding the right strength
Hold the frame, the prompt and the seed, then sweep one LoRA's scale from 0.5 to 1.5 across four runs at 480p. Above roughly 1.5 the style tends to consume the subject instead of styling it. Keep the run where the style is present and the subject from the frame is still intact, and rerender that combination at 720p.
Prompt guide & pro tips
Choose the slot before you write
Decide what the LoRA is supposed to change. Rendering style goes in the low-noise slot, motion or camera style in the high-noise slot, and the shared slot when the style should touch composition and texture alike. The prompt then only has to describe what moves and how the camera behaves.
Do not name the style twice
Naming a style in the prompt while also loading a LoRA for it tends to double the effect. When a LoRA carries the look, keep the prompt about action and camera, and adjust the strength instead of adding more style words.
Adapt the included example
The rooftop-walk example runs at duration_seconds 5 and resolution 480p with all three LoRA slots empty:
She pushes off the railing, straightens her blazer over one shoulder and turns to walk along the rooftop, city lights and the vending machine glow sliding past behind her, hair lifting in the night wind. Smooth tracking move, anime cel-shaded style held stable.Run your own frame with a prompt in the same shape (one action, one camera move) and a fixed seed to get the base clip. Then add one weights URL to a single slot at scale 1, keep everything else unchanged, and compare the two clips to see what that LoRA changes.
Set length, seed and frame deliberately
duration_seconds accepts only 5 or 8, and any other value is rejected rather than rounded. For the seed, 0 requests a random draw, so use a non-zero value while you sweep. The frame can be JPEG, PNG without transparency, BMP or WebP of up to 20 MB, and the clip takes its aspect ratio from it, so crop it to the delivery shape first.
API quick start
Call the Wan 2.2 LoRA API in three steps
- Create an API key. Sign in to PopNow and create a key in the API console. Keys start with sk-popnow- and use the same credits as the website.
- Send the request. POST /jobs/createTask with model alibaba/wan-2.2-lora/image-to-video and an input object that follows the parameter table. The response returns a task ID straight away.
- Get the result. Poll GET /jobs/recordInfo with the task ID, or pass a callBackUrl and we post the result to it. Download the output links when the task succeeds.
# 1. Create the task. Keep the Idempotency-Key if you retry after a network error.

# 2. Copy data.taskId from the response, then poll until state is succeeded, failed, canceled or expired.

Wan 2.2 LoRA API questions
How much does the Wan 2.2 LoRA API cost?
Wan 2.2 LoRA starts at 18 credits ($0.18) for a 5-second clip with Image to Video, its cheapest task. Prices by option: 480p 3.6 credits per second, 720p 7.2 credits per second. Credits are the same as on the website (1 credit = $0.01), new accounts get 30 free credits, and failed tasks are refunded.
What is the model name for Wan 2.2 LoRA in the API?
Put alibaba/wan-2.2-lora/text-to-video for Create Video; alibaba/wan-2.2-lora/image-to-video for Image to Video; alibaba/wan-2.2-lora/video-extend for Extend Video in the model field of POST /jobs/createTask.
How many LoRAs can I attach?
Up to three per slot, and there are three slots: loras, high_noise_loras and low_noise_loras. Each entry is a direct weight URL plus a strength from 0 to 4, defaulting to 1.
What is the difference between the three LoRA slots?
Wan 2.2 denoises in two passes. high_noise_loras attaches to the high-noise expert, where composition and motion are set; low_noise_loras attaches to the low-noise expert, where detail and texture resolve; loras applies to both at once. A LoRA published as a high-noise and a low-noise file goes into the matching two slots.
Where are the weights stored?
On your hosting. Each file is fetched from the URL you supply for the duration of the run and nothing is stored, so weights that must stay private should sit behind a signed link.
Which links work?
A direct download link to the weights file always works. On image-to-video, files may be up to 1 GB and Civitai model pages or Hugging Face /blob/ links are also resolved to the file. On text-to-video, link the .safetensors file itself: a repository page fails the run, and so does anything behind a login.
How long can a clip be?
Exactly five or eight seconds. duration_seconds is an enum, so a value like six is rejected rather than rounded.
What are the limits of the Wan 2.2 LoRA API?
Clip length: 5–8 s; Resolutions: 480p · 720p. Requests outside these limits are rejected before anything is charged.
Can I try Wan 2.2 LoRA without writing code?
Yes. The Playground runs Wan 2.2 LoRA on your PopNow credits, needs no API key, and shows the matching code for every run.
