Issues with center_crop scaling in WorldMirror-based reconstructor

[znx-hub]

Thanks for the amazing work on this project! While using the pipeline, I manually saved and inspected the intermediate 4DGS results. I ran into an issue when using the default settings on my own dataset.

When I used the default center_crop (which includes scaling) to preprocess my 1170×540 images into 560×336, the results weren't great. However, I tried skipping the scaling and just doing a raw center crop instead, and the output quality improved significantly.

It seems like the scaling in the current center_crop might be messing with the 4DGS prediction. However, this doesn't seem to happen with the scaled images you provided. Is there something wrong with the way I'm processing my data?

Thanks for your time!

Hi! Is there any problem with center-cropping the original images to $560\times 336$?

Sorry for the confusion. I just realized I mentioned 560×360 earlier, but I am indeed using the default settings from center_crop (which targets 560×336). I'm just using center_crop directly from diffsynth.utils.auxiliary, so I don't think I'm doing anything unusual.

Would you mind sending me some cases (preferably videos) for debugging? My email is yangyuxue2023@ia.ac.cn.
