MLV App dark frame subtraction creates extreme noise

Oh okay, yeah the dark frame was definetly recorded at a totally different day at totally different temperature. With the battery I am not sure because I let it run all the time from a dummy battery adapter and power directly from a powerbank.

To be honest I hoped I would record once the dark frames for various settings and have them "forever" in the folders for future darkframe substractions and to not record every single time a darkframe video for every single shot I take

Should work better even if the darkfram was recorded afterwards. Subtraction works best with 14bit and maybe ok with 12bit files. 10bit files not good imo.

@cannibalferox you can try "pre-heating" your camera, let it run for a few minutes with high iso recording video.. then record mlv for dark frames. maybe it will be close enough..
