First of all Tell me what kind of MicroSD card you are using, this firmware is customized for FAST MicroSD cards as UHS-I or UHS-II with speeds of at least 50-70 Mbps Write speed, you can even use x633 UHS-I which is with guranteed write speed 90 Mbps.
BUT there is no need of my ROM anymore

, please use the stock one from the Xiomi official web site for your camera version and just use this script which enables all the
VIDEO resolutions ONLY which can be selected through the app to the following Bitrate speeds:

#t ia2 -adj tidx [ev_idx][nf_idx][shutter_idx]", "-1 disable"
#looks like the values are between 0-16383 (0x0000-0x3FFF)
#If you want to set noise reduction value to 2048 just remove the hash key from the row below and for all the resolutions you will have sharpness as craze
#t ia2 -adj tidx -1 2048 -1
So you see that you can even set the noise reduction value to whatever you want, I tried 1024 and in the night there is too much noise in the video so 2048 is a bit better, but this setting is not good for night video even if the Auto low light is turned on !
And here is the file it self:
