Yes, the DJI Mini 3 Pro uses DCG HDR technology, which is different from standard HDR (stack technology). DCG HDR is an HDR technology for CMOS, which can capture details in dark parts without losing details in highlights, thus generating multi-exposure fusion video. This video has a higher dynamic range compared with ordinary video, but the generated file is not standard HDR footage. So after being imported into the color correction software, there are no obvious visual differences between the HDR video of DJI Mini 3 Pro and a high frame rate video with the same specification. You can adjust the exposure curve to see the differences in the dark part details.
Dji Paladin,
Based on your past replies the so called HDR video (when shot in 24/25/30fps HQ mode) is not showing any such difference in dynamic range when compared with 48/50/60fps video.
So my question is what is the HQ mode doing internally which is giving better quality video while adjusting exposure curve? (Mainly lifting the shadows up)
Is it higher bit rate, or better noise reduction in HQ videos?
I did another test of extreme highlight & shadows then lifted the shadows way up than I usually would lift up. There is minor difference & looks like HQ is doing some greater noise reduction. Dynamic range no difference.
Conclusion - There is NO HDR in mini 3 pro, whatever it is doing is not standard HDR HLG profile.
