At 17:24 you mention that there is no way to have Blender add the "Frame Name" to the rendered frames. I was wondering why you couldn't rename the Marker with the Frame Name. That way under the "Output Properties" -"Metadata" you can choose to see the name of the "Marker" on each frame. Is it somehow different for Grease Pencil objects? I know previously I have rendered PNG Sequences with this type of Metadata and it does place it on the border around the frame. You can even add a "Note" to be included with each frame and/or choose to have the information burned into the images themselves - instead of around the border.
I MUST LOOK INTO THIS! THANKYOU! The goal is to have the render adopt the name of the marker, ie: Frame 001 would render out labelled A_frontcover.tif. I was looking at python solutions, but if this works - I'll put in a quick subtitle edit into the video. No it would not be different for Grease Pencil objects, I just did not know about this before. I will happily admit the fault lies with me!
Ah ok - so it adds metadata as an overlay - not great for printing the final, TBH.
The issue is that the file needs to be named specifically. So Frame001 needs to be named A_frontcover.tif; Frame002 needs to be named B_insidefront.tif, etc. If anyone knows a way to override the output file naming for this mased on the Marker's name, that would be AWESOME!
