Apple ProRes with Dlog on Mavic 3 Cine is very poor quality. It's a huge disappointment for me. Check out the attached video. The original video converted to QuickTime APR422HQ shows the same issues.
The first 10 seconds are shot in Apple ProRes 4K 50P in normal mode (ISO 100, ND8, F4, 100fps, exposure MM-0) with no editing, the image is fine, maybe a little bit sharp and too contrasty.
The second 10 seconds is shot in Apple ProRes Dlog 4K 50P (ISO 400, ND8, F8 100fps, exposure MM-0), DJI LUT applied plus basic editing (saturation, contrast etc) in Adobe Premiere CC 2022. In Dlog mode, the blue sky has a disintegrating image, totally damaged with visible blocks. It looks like the Log profile was applied to 8 bit video. A massive codec like Apple's ProRes HQ can't behave like this, right? What do you think?
The link to download the original files without editing is in the description of the YouTube video.

I downloaded your source videos and found them both to be excellent.

First of all the normal ProRes looks like it is 10 bit color after all, it also looks excellent. I would turn down the sharpening and contrast in camera for more latitude in post but the imaging processor nailed it in on this one. A quite strong s curve is being applied and some other tone mapping as well as computational adjustments are being made in camera. It’s looks nice.

The D-log looks and graded excellently. You were a little under exposed though. Next time don’t change camera settings going from normal to D-log. I know people get messed up on the fact that it forces you to use a higher ISO in DLog but this is just gain, it can be undone in post and it’s not the same thing as actual exposure ie aperture and shutter speed and is different from photo mode. Usually you want to expose log a little more. And BTW the in camera light meter doesn’t work correctly for log. On the Inspire 2 it literally gets disabled when shooting log to avoid confusion.

The D-log doesn’t get the computational adjustments and looks quite soft without it. We are seeing the effects of the limitations of making such as a small lens for this sensor. It’s quite poor compared to the Inspire 2. They are doing a good job of correcting it in normal mode but D-Log doesn’t get this. Usually I’d find that to be a good thing but it’s too soft for my taste.

If it were me I’d stick with that normal mode ProRes but lower the contrast and sharpening. It’s clear the DLOG is capable of holding a lot more dynamic range but we’ll have to see both modes pushed to the limit to see if it’s really worth it. So far it doesn’t look like it.

But we cant turn down the contrast and sharpening 'in camera' which is a big shame as this is really all the 'normal' video needs to give a great starting point. Is there any indication from DJI that they are planning to introduce these controls in a software update?

I didn’t realize you couldn’t adjust them. Is that only for ProRes or for h.264/5 too?
