Workflow:

1. Decompress the binary (this step has already been done):
 FWDV180N_orig.bin new_firmware.rbn

2. Modify resolution/bitrate in new firmware:
 Execute NtkMPE.jar, load new_firmware.rbn, modify settings, press "Apply modifications"

3. Compress new firmware
bfc4ntk.exe -p new_firmware.rbn new_firmware.bin

4. Write new checksum to compressed firmware
ntkcalc-v051.exe -cw new_firmware.bin
