If you cool CMOS sensor, you may get as high as ISO 3200 and maybe ISO 6400. Hot pixels then are not present. To decrease noise, use 'echo' under 'time' effect in Adobe Premiere - no more than 3 echoes if you shoot toward south, or no more than 6 echoes if you shoot toward north. Each echo is added by setting 'maximum', which adds only brighter light. So, for example 3 echoes means equivalent of 4 x 7.9 seconds exposure. At least one echo may give you much better results with less noise. Currently I am trying one lens with removed IR cut filter (not possible with original Xiaomi Yi lens). I removed lens from Firefly 6S and just crush IR cut filter, and mounted onto Yi camera. Will see how it will looks like. Great video anyway!
