Inquiry About Model Support for Flexible Resolution Handling

[xuhuanstudio]

Dear Author,​​

Thank you for your great work. While using your model, I encountered the following issue:

In real-world applications, we often need to process images of various resolutions. The current approach forces all inputs to be cropped to a fixed aspect ratio, which results in significant loss for portrait-oriented images (where width < height).

I tried padding the edges to match the target resolution, then cropping afterward, but this drastically reduces the effective resolution of the main subject. Another workaround is rotating the image by 90°, processing it, and then rotating it back. However, I noticed that the model handles ​​d_theta​​ and ​​d_phi​​ differently—​​d_theta​​ seems to perform much better.

Could you confirm whether future updates will support flexible resolution handling? Looking forward to your insights.

hi, do you have some good solution for this now~ I also suffer from this. In practice, this image resolution is always variable, while the hard coding force_1024 introduce center crop... thanks~~~

We’re excited to announce that a new model will be launched in September, featuring substantial performance gains, and enhanced support for flexible resolutions and extended video lengths. Stay tuned!

Hello, I found that if you directly search for "576" in the project, you will find a code snippet about forced cropping of images. Just modify it to the desired size.

Thank you, I also saw this before. But, to my knowledge, the difficulty of using flexible resolution is the restrict of ViewCrafter Video Diffusion Backbone Model. It was trained on fixed resolution.

In my case, directly resizing the image to a resolution of (1024, 576) would cause distortion, which makes it difficult to adjust the camera's intrinsic and extrinsic parameters accordingly.
