How to Animate a Drawing Locally: Loomance vs ComfyUI on WAN 2.2

A side-by-side test of two local, no-cloud ways to turn a still image into a short animation on a single mid-range GPU — a manual ComfyUI node graph, and Loomance's three fixed workflows.

Published September 2026 · Updated October 2026 · HumansAI Studio · Tested on RTX 5070, 12GB VRAM

Quick answer: Both tools can run the WAN 2.2 image-to-video model entirely on your own GPU, with no cloud rendering and no per-render credits. ComfyUI gives full node-level control over the diffusion pipeline at the cost of manual setup. Loomance wraps the same model in three preset workflows — Stable Scene, First → Last Frame, and Wild Mode — built to run on a 12GB-VRAM consumer GPU without configuring a single node.

Why animate locally instead of in the cloud?

Running image-to-video generation locally means no per-render credits, no upload of source images to a third-party server, and no dependency on a subscription staying active. Both ComfyUI and Loomance render on the user's own GPU using the WAN 2.2 model — the difference is how much manual configuration stands between you and a finished render.

Keeping a character consistent across an AI-generated video

One of the hardest problems in image-to-video generation is character drift — the subject subtly changing from frame to frame instead of staying visually identical to the source image. In a same-model, same-hardware test, a standard ComfyUI workflow showed three recurring issues:

Character drift — subjects were redrawn frame to frame rather than held consistent with the first frame.
Temporal artifacts — fast motion caused visible blurring/blending between frames.
Static backgrounds — environments stayed completely frozen, since the workflow preserved stability by simply not moving anything in the background.

Loomance's Stable Scene workflow targets this specifically: character design, art style, and environment are held fixed while only motion — including subtle ambient background movement — is added. In this test it rendered at 1536×864, 54 frames, 23 FPS, with fewer visible artifacts during fast motion than the ComfyUI baseline.

First → Last Frame: animating between two anchor images

Both tools support giving the model a starting image and an ending image and letting it render the motion in between. Loomance adds a built-in frame extraction tool: any rendered video can be split into individual frames inside the app, and any extracted frame can then be reused as a new start or end frame for a follow-up render — so several renders can be chained into one longer sequence without visible jump cuts once stitched together in a video editor.

Test case: a start frame of an archer drawing her bow, and an end frame of an apple pierced by an arrow. Loomance rendered the connecting motion (57 frames at 24 FPS) as a single continuous sequence, keeping the character and art style consistent from the first frame to the last.

The same First → Last Frame workflow also works with two AI-generated anchor images (for example, from ChatGPT), or with a child's hand-drawn sketch as the starting image.

Can I turn a hand-drawn sketch into an animation?

Yes — a crayon or pencil sketch works as a source image for both Stable Scene and Wild Mode. In testing, a child's drawing of an animal was used directly as the source image and rendered into a short animated clip on the same 12GB-VRAM GPU, with no upscaling or cloud processing required.

Wild Mode: when you want the AI to reimagine the scene

Wild Mode is for creative transitions, transformations, and style changes — for example, a drawing turning into a cinematic 3D scene, a cartoon, or a black-and-white retro comic. Unlike Stable Scene, it treats the source image as inspiration rather than a fixed template, so two renders from the same sketch can look completely different by design.

Hardware used in this comparison

GPU: NVIDIA RTX 5070 (12GB VRAM)
Resolution: 1536×864 (standard 16:9)
Frame counts: 54–57 frames per render
Frame rate: 23–24 FPS

What Loomance needs to run

Windows or Linux with an NVIDIA GPU (12GB VRAM recommended; 8GB works at lower resolution)
32GB RAM and about 40GB of free disk space (the first-run model download is about 38GB)
An internet connection to start the app. Rendering itself runs on your GPU and your images are never uploaded.

Frequently asked questions

How do I animate a drawing locally without using the cloud?

Load the image into a local image-to-video tool built on the WAN 2.2 model — ComfyUI (manual node setup) or Loomance (preset Stable Scene, First → Last Frame, or Wild Mode workflows) — and render on your own GPU. Rendering runs entirely on your own GPU and your images are never uploaded. Loomance needs an internet connection to start.

Is there a ComfyUI alternative that doesn't require building node graphs?

Loomance runs the same WAN 2.2 model as ComfyUI but exposes it through three fixed workflows instead of a node graph, so no manual sampler, scheduler, or LoRA wiring is required.

How much VRAM do I need for local AI video generation?

This comparison ran on an RTX 5070 with 12GB of VRAM at 1536×864 resolution, which was enough for both ComfyUI and Loomance running WAN 2.2.

How do I keep a character consistent across an AI-generated video?

Use a workflow tuned for stability rather than free reinterpretation. Loomance's Stable Scene workflow keeps character design, art style, and environment fixed while adding only motion, which reduced drift and temporal artifacts compared to a standard ComfyUI setup in testing.

Can I turn a child's drawing into an animation?

Yes. A hand-drawn sketch can be used as the source image in a local image-to-video workflow to generate an animated version of the drawing, rendered locally on a consumer GPU.
