Final dataset is 0 frames

Hello everyone,

I’ve been trying for the past few days to convert my data extracted from Metashape to the nerfstudio format, but I’ve been always running into the same issue and I’m not really able to solve it.
My folder is called NS0004_Philipp and it contains an “images” folder, with all of the frames I need, and a cameras.xml file.
The “images” folder was extracted from Metashape through File -> Export -> Convert Images, while the cameras.xml was extracted from Metashape through File -> Export -> Export Cameras.

However, when I run the following command ns-process-data metashape --data data\NS0004_Philipp\images --xml C:\app\NerfStudio\data\NS0004_Philipp\cameras.xml --output-dir data\NS0004_Philipp_output the output I get is always the same:

The output folder gets created, but the transform.json file is practically empty:

For reference, I'm using a setup with 42 cameras and my cameras.xml file looks like this:

Hi @ariannaferraris
I'm also facing the same issue. Did you happen to find the solution?
Many thanks

For my case I managed to solve my issue by appending the --verbose flag to the ns-process-data command (suggested in #1634) which showed me that the images were of an unsupported apsect ratio, so I just used the original images not exported through metashape.
