Recommendations for reducing digital noise on video (NX300)

I've been shooting videos at 720p with my NX300 and a f/2.0 30mm lens set on aperture mode, which means manual focus, automatic ISO and automatic shutter speed. Usually I film indoors with every light I have on. Recently I've noticed a lot of digital noise from the very beginning of each video (so even with a "cold" sensor), which could be partly due to the heat of these months.

I've seen people on youtube testing their NX300 with kit lenses at night with almost no digital noise but I don't seem to be able to achieve a similar result.

Could you give me advices on how to set the camera in manual mode in order to reduce the grain as much as possible?

I forgot to say how. I too shoot in A mode. Just click iso button and try setting it as low as possible. It's belowbelow the ok button.

This is what was not working. On A mode, even if I set a specific ISO, once I press the record button the ISO goes to auto.
So I have to go back to manual mode only. This also explains why all of a sudden all my videos were grainy, I was using A mode thinking that ISO would be what I set. I never noticed that ISO went in automatic mode as soon as you record video.
