Aside from the time/effort involved. Is there a downside to doing this and/or anything you miss out on or that could be improved upon further from your tutorial?
Also, what would it take to analyze for multiple trims or does it already do this? Have you ever attempted this?
Also, I followed the guide and generated this for The Super Mario Bros (2023):
Does this look correct?
Here's the
DoVi XML and
HDR10+ JSON as well.
Also, thank you RESET_9999 for putting together these tutorials and scripts!

How would i bake the EL into the BL?
This is for FEL titles only correct?

also, the latest version of my script can encode P7 FEL to P8.. Workflow (6-9)

The only thing I don't do in the video is the project image scaling. I found out that if you set your project to 1080p with cubic algo, it produces much better metadata that are almost identical to the original.

Your project set to CMV4.0 will produce L2 trims. My script by default, will remove them as explained recently in this thread.

Would baking the FEL layer into the base layer not create a profile 5

It creates a new HDR10 base layer with P8 original dv metadata

So does it retain hdr10 fallback?

of course, no different than any HDR10 + P8 encode.

You gain extra quality/brightness from the FEL.

So then would it be the same if played back as HDR10 or DV

only if you compare it to DV on a device that support FEL.
What would be the command line to accomplish this?
I posted my cli a couple post ago.

Workflow 6-9 using your scripts?
I was referring to using dovibaker

Just curious, do you know why this produces better results?
Also, have you considered adding this note to the video description on YouTube? It might help others who follow along, but don't come read this message.

Why set the project to CMv4.0 instead of CMv2.9 then? Would you not get better results just initially setting to CMv2.9
to avoid the issues you demonstrated here with CMv2.9 when CMv4.0 analysis is used?
