I hava the same question.Did you have solved the questions?

[gulj9]

I haven't solve that yet but I got around it. If you disable the viewer you can dump the video to disk without using the viewer.
I found this video helpful: https://www.youtube.com/watch?v=K0mSOAXOtDs&t=283s
I used this code:

import genesis as gs
import numpy as np
gs.init(backend=gs.cuda)

scene = gs.Scene(show_viewer=False)

plane = scene.add_entity(
gs.morphs.Plane(),
)
franka = scene.add_entity(
# gs.morphs.URDF(
# file='urdf/panda_bullet/panda.urdf',
# fixed=True,
# ),
gs.morphs.MJCF(file="xml/franka_emika_panda/panda.xml"),
)

cam = scene.add_camera(res=(640, 480), pos = (0,3,2), lookat=(0,0,0.5), fov=30, GUI=False)
scene.build()
cam.start_recording()

for i in range(360):
scene.step()
cam.set_pose(
pos= (3.0 * np.sin(i/60), 3.0*np.cos(i/60),2),
lookat=(0,0,0.3)
)
cam.render()
cam.stop_recording(save_to_filename='test1.mp4', fps=60)
