Hello, thank you so much for making your work open source.
I am trying to use other data from DAVIS. But the source virtual view created by render_source_vv.py is bad.
This is the original image.

This is the virtual view image.

But I think the model reconstructed by colmap is good enough.
train_colmap_reconstruct

I wonder if there is some mismatch between colmap output and dynamic-video-depth. Or could you please give me a pair of input and output for colmap and dynamic-video-depth to help me find out my mistake.

Thank you a lot!

Hi, the virtual view image looks OK to me. Why do you think it's bad?

Thanks for your reply!

This is virtual view image provided by you. I think it may be closer to the real situation, which reflecting the depth and disparity.
And the image resolution seems to be lower.

I try to set the novel view camera offset fixed to be (0, 0, 0.1). But the output is not as good as your demo. I am trying to find out why.

Maybe I should check the NSFF part?
