Hello DJI Team,
Zebra is the only useful tool in the Fly App for getting overexposure warnings, for example for not to lose details in clouds.
However, the zebra function works very poorly with the Mavic 3 (Classic) in D-Log.
D-Log clips at 84 IRE in NLE's waveform scopes (about 856 in Resolves data levels), but Zebra is already shown on the DJI RC in D-Log View at 80 IRE (about 820 Data Levels), which means about 2/3 f-stops too early.
It is even worse if you activate the Log Display Assistant (ultimately a Display LUT), then the zebra is displayed another f-stop earlier, so about 1 2/3 f-stops are wasted if you orientate yourself on it. Or in other words: 1 2/3 stops of usable data in the container is wasted, if you use Zebra for Overexposure warning.
Please pass this on to the dev team. It would also be nice if the display assistant tool still take the real log clipping of the footage into account, not the Rec709 display clipping after applying the LUT
Thank you!
Besides that, the Mavic 3 Classic is awesome, especially the D-Log implementation - very close to S-Log3, which simplify things a lot. Finally a huge upgrade from the Mavic 2 Pro reagarding dynamic range, color and details. Great job!
