Good day!
I would love to have some settings that the export is always put into a folder named like the export Date.
This is something I'm looking into!
And maybe be able to even use some of your projects bin structure to name the folders where it should be exported.
A simple trick might be to use parent bin name (a bin where sequence to be exported is placed) as a wildcard for naming output folder.
Also Wildcards for the export name based on date version or even a abbreviation for the editor on the project.
I don't think I will do anything about actual export, because this will require me to launch export itself. For this I offer to use Excalibur (also I will add some of your ideas to Excalibur 🙂)
Also I think you can add some of that info in the sequence name (because Premiere Pro uses sequence name as a file name). This is not a dynamic solution, of course.
