Hi, I am using the below script to record an SVO with my ZED X

status = cam.open(init)
if status > sl.ERROR_CODE.SUCCESS:
print("Camera Open", status, "Exit program.")
exit(1)
recording_param = sl.RecordingParameters(opt.output_svo_file, sl.SVO_COMPRESSION_MODE.H265) # Enable recording with the filename specified in argument

if err != sl.ERROR_CODE.SUCCESS:
print("Recording ZED : ", err)
exit(1)

print(f"SVO is Recording at {opt.fps} FPS, use Ctrl-C to stop.") # Start recording SVO, stop with Ctrl-C command
frames_recorded = 0
while True:
if cam.grab(runtime) <= sl.ERROR_CODE.SUCCESS : # Check that a new image is successfully acquired
frames_recorded += 1
print("Frame count: " + str(frames_recorded), end="\r")
if name == “main”:
parser = argparse.ArgumentParser()
parser.add_argument(‘–output_svo_file’, type=str, help=‘Path to the SVO file that will be written’, required=True)
parser.add_argument(‘–fps’, type=int, help=‘Camera framerate (e.g. 15, 30, 60, 100)’, default=30)
opt = parser.parse_args()
if not opt.output_svo_file.endswith((“.svo”, “.svo2”)):
print("–output_svo_file parameter should be a .svo file but is not : ", opt.output_svo_file, “Exit program.”)
exit()
main(opt)
But it still records at 30 fps as seen in the log below.
