Hi I am just trying to understand, 8 bit,  10bit, is that the same as d-log.?so does this mean dji got the specs wrong with this photo option, if so what else did they get wrong like that it has 18klm transmission in 1080p.coz people are complaining that they can't get more than 500m to a 1000 with out dropping out. Cheers

I don't know, I would wait until DJI officially conforms that.  One tec could be wrong.  So far it's just chatter hopes an dreams.

Your misunderstanding the 18km transmission, that is related to how far the battery "could" go, not transmit range

Well it definitely is the case. I checked the footage and compared 8-Bit (normal) with the 10-Bit (D_Cinelike).
The 2 more Bits are filled with color information. Especially for this comparison, I created two files of footage, showing a 99% clear blue sky. Filmed nearly at the same time.

Just take this footage into Resolve or Premiere and push the contrast heavily. You will not only see it on the wave form scopes but clearly in the image how the 8-Bit footage falls apart and the 10-Bit does a quite good job.

Check for yourself, here is the sky sample footage: Mini3_Sky.zip (400mb)

I noticed that yesterday too when comparing bitrates for each framerate in Quicktime, they show as follows...

Normal

24 (23.98) - 8 bit: 95.51 Mbit/s
25 - 8 bit: 90.68 Mbit/s
30 (29.97) - 8 bit: 94.71 Mbit/s
48 (47.95) - 8 bit: 114.47 Mbit/s
50 - 8 bit - 110.19 Mbit/s
60 (59.94) - 8 bit - 153.15 Mbit/s

D-Cinelike

24 (23.98) - 10 bit: 94.57 Mbit/s
25 - 10 bit: 91.93 Mbit/s
30 (29.97) - 10 bit: 93.14 Mbit/s
48 (47.95) - 10 bit: 112.91 Mbit/s
50 - 10 bit - 110.93 Mbit/s
60 (59.94) - 10 bit - 152.46 Mbit/s

So the bitrates remain the same for both colour options but the D-CineLike is reported as 10 bit. MediaInfo shows the  D-CineLike files as being 10 bit 4:2:0 (Main10@L5@Main)

Are these in the HQ mode or not?

One theory is the "fake hdr" method used reports as 10bit as a software hack to get it displayed.

Well this theory is quite unrealistic as you cannot record 60fps in "HQ" mode, but you can record 60fps in 10 Bit D_Cine.
