Render mp4 video without GUI (base_cam.json format needed)

[pavanKumar6720]

I am working on a remote server with V100 gpu.
Since UI is not available, I am not able to generate "base_cam.json" (which is needed to save animations) through testbed.
Is there any way to render an animation (mp4) through script (without GUI)?
Is there any documentation on base_cam.json format?

Hi there, base_cam.json is currently undocumented and expected to be generated through the GUI.

If you already know the camera matrices for each frame of your animation, you could generate a new transforms.json file with empty filenames and use run.py --test_transforms <your transforms.json>.

Alternatively, you can also directly set the camera matrices through the python bindings (see run.py for how this is done in the case of the --test_transforms argument).

Cheers!
