Meaning of High L4.2 in Media page Metadata

Here's something I've never seen before. If I open the metadata on a clip in the Media page before it's brought into Resolve I see H.264 High L4.2. All clips from my Canon G40 now have this addition. If I open the Metadata on an imported clip it merely says H.264. What does High L4.2 mean?

High Profile
Level 4.2

Thanks Jim. So does it mean that Resolve is not interpreting it properly when it only shows H.264 in the Metadata after the file is imported?

This gets interesting. If I look at a rendered file in the Media page, an HD render is Main L4.2, a UHD one is Main L5.2. Another UHD one is Main L5.1 and another HD one is Main L5.0.
This looks to be a complicated subject.

It all depends on the generating program and its settings. Only the information got more detailed in 17.
