Plugging in a HVEC encoded HLG (hybrid log gamma) file created from a Mavic 2 Pro into a HDR compatible TV was a stunning experience. Right out of the SD card, one realizes vibrant colors and a pleasant experience. I realize that a very bright monitor and HLG compatible 4K monitor is necessary to realize full dynamic range but for what its worth I'm hooked. Its not clear to me if the video is recorded in a different color space (Rec 709-10 bit?) or REC 2020 (likely the former). How does this matter?

As I understand, most pros still work in the traditional workflow and don't think much of the HLG feature, prefering to work with M DLOG. Can someone (DJI) post a tutorial or a link to such to educate the rest of us?

Also, from DJI: how likely are we to see such features ported to the I2 platform. It seems the video processing engine in the Mavic 2 is the new Amberella H3 which is mighty capable so maybe not as the I2 has an older chip. Raw with either the X5S or X7 sensors trumps whatever the M2 can do of course but I wonder how many of the 'new' features will affect how pros work. Interested to hear....

I had a similar post & nothing returned in way of info.  I google & all I find are people asking questions.  

I tried Dlog-m & HLG.  I thought Dlog was to be 10bit 422 HDR, but get info on the file doesn’t state that,  so I’m confused which is capable of what features.

DJI should put up a tutorial -they usually do a good job when they do so. 10bit is after all a selling point for the M2....

Hello,

Just registered on this forum to ask single question... And realized that I cannot ask this question because I have no points!
Very interesting... No rights for newbies to ask questions on forums regarding Mavics they purchased? How to get points then?

Ok, if I cannot create New Topic I have to ask my question here:
I have LG OLED TV which supports HDR HLG files. So internal TV players recognized MP4 files from my Mavic 2 pro well and plays it. But the problem is this TV has just 100Mb network. So 100+ Mb bitrate MP4 files from Mavic are played with microfreezes on TV. I decided to buy Mediaplayer which supports  HDR HLG. But made research and didn't find universal HDR HLG capable player on the market?
Probably it is just not advertised, and HDR support includes HLG as well? Can someone recommend me how to watch content from Mavic on HDR HLG capable TV please?
And regarding HDMI2.0b - is it really required for HLG to work through HDMI? Or HDMI2.0a is enough?

For the LG series OLED TV - anything made from 2016 onwards will play HLG content if the firmware is updated. Network speed has no influence whatsoever on the ability to play back such media. The TV is more than capable of reading from a micro-SD card. You play the material by plugging in the card into a USB reader. Playing the content through an external player doesn't give the same (brilliant) results

Dlog-M is 10bit 420 SDR. In other words, it is 10-bit REC. 709
