ViewCrafter can generate high-fidelity novel views from a single or sparse reference image, while also supporting highly precise pose control. Below shows an example:
Reference image | Camera trajecotry | Generated novel view video |
Reference image 1 | Reference image 2 | Generated novel view video |
Model | Resolution | Frames | GPU Mem. & Inference Time (A100, ddim 50steps) | Checkpoint |
---|---|---|---|---|
ViewCrafter_25 | 576x1024 | 25 | 23.5GB & 120s (perframe_ae=True ) |
Hugging Face |
ViewCrafter_16 | 576x1024 | 16 | 18.3GB & 75s (perframe_ae=True ) |
Hugging Face |
ViewCrafter_25_512 | 320x512 | 25 | 13.8GB & 50s (perframe_ae=True ) |
Hugging Face |
Currently, we provide three versions of the model: a base model that generates 16 frames at a time, an enhanced model that generates 25 frames at a time (used by default), and a low-resolution model that produces 25 frames of 320x512 video. The inference time can be reduced by using fewer DDIM steps.

(1) Download pretrained model (ViewCrafter_25 for example) and put the model.ckpt
in checkpoints/model.ckpt
. \
(2) Run inference.py using the following script. Please refer to the configuration document and render document to set up inference parameters and camera trajectory.
sh run.sh
Download the pretrained model and put it in the corresponding directory according to the previous guideline, then run:
python gradio_app.py

β οΈThis is an open-source research exploration rather than a commercial product, so it may not meet all your expectations. Due to the variability of the video diffusion model, you may encounter failure cases. Try using different seeds and adjusting the render configs if the results are not desirable. Users are free to create videos using this tool, but they must comply with local laws and use it responsibly. The developers do not assume any responsibility for potential misuse by users.
