D Log M (with Auto ISO) Superior to D Log

Yes, thank you for the that but I was hoping to hear from the author of that YT video or his supporters/admirers on this forum to offer some explanation how this suppose to improve dynamic range and provide other benefits to video quality. But only silence so far from that end..

I suspect, based upon one of the comments on his YT video, that he may have performed the testing incorrectly, and come to a false conclusion. He's still enjoying the views and doesn’t want to admit his mistake.

Your assessment might be right on the money

Did you comment or DM them on the video?I don’t think the author of that video lives in this chat.

If you lock exposure, there is no benefit to having previously selected Auto ISO, other than deciding which ISO to use throughout. You might as well have selected any single manual ISO to start, which is exactly what you have done, when you lock exposure after having chosen Auto ISO.

My thought was more that you can have a more precise ISO increment selection. Otherwise you are stuck with selecting an iso manually at around 100 and only being able to go up to 200 or 400 in larger increments. The auto feature will go in between. But either way, unless we can reproduce the results on the video I think to each their own, we call the shots and decide what we think it’s best for our case. Nobody is wrong in the art of filmmaking. It’s just a choice we get to make.

I agree but if someone is making claims to only get clicks on his YT channel he needs to be called out.
M4P has 1/3 EV increments in Manual mode. While not as gradual as 10 point increments in Auto Mode better than full stops. But even 1/3 is plenty sufficient to achieve accurate exposure. I was more concerned (and therefore responded here) about his claim of above 17 EV of dynamic range. Arri Alexa has 17 and that is one of best cine cameras in the world! His methodology was obviously flawed and some members here seem to have fallen for this click bite hence my response and my questioning of his claim.

What makes you think methodology is flawed? Just because you don’t believe the results?

Because of their own admission about their methodology at around 9min time in the video. Quote: "This could be correct or widely incorrect".
In other words believe what you want to believe. My alarm bell usually rings loudly when I hear a claim that a prosummer camera has greater dynamic range than the best cine cameras in the world such as Arri or Red...

Can not argue with that !!
