red pixels

I did a timelapse of the sky last night @18db and 1/3 second. In the footage there are two clear red pixels, that I do not see under 'normal' shooting circumstances. Also not when shooting (very) dark scenes. Does someone know where this comes from and what to do about it?

Re: red pixels

I recall from my trv 900 days that under these circumstances - high gain and low shutter speed at 24p - hot pixels on the sensor that don't show up under normal shooting specs can show up. That might be the case. It was a serviceable issue, as I recall, though this was long ago.

It is possibly dust on the sensor. I already had that issue but was easily fixed.

Re: red pixels

You could try black balancing. Sometimes recovers lost or stuck pixels.

Re: red pixels

Someone on another forum had this same issue. Black balancing should correct this.

Re: red pixels

Thanks all. Black balance did the trick. What worries me however is the remark in the manual: "The adjusted settings are stored only temporarily. The settings return to the default settings when you turn the power off."

I did not see the red pixels reappear after switching on/off, but does this risk exist?
