Is it possible to pass variables to the post-processing node?

I've still never gotten Adobe Media Encoder to work correctly with Pro, but I decided to whack my head against it again :) But that's for a different thread.

I've been poking at youtubeuploader, which is a CLI tool to upload videos to youtube, and it seems to work correctly when invoked by Postproc nodes in the Designer. However, I don't see an obvious way to use individual file names in the process.

My test setup is basically this: I've got a normal setup in a copied scene, so that I know the output file is fine; I can then add a Postproc node after the Output (file) node that runs youtubeuploader. The syntax for uploading is youtubeuploader -filename <filename>.mp4, which means I'd need to use the same generic name for every rendered video, since it's hard-coded into the Exec line in the Postproc node. While workable, I'd really like to avoid that, especially when I have a couple renders queued up!

Before I whip up a script to guess & rename the video before upload, I just wanted to check to see if there was a built-in way to pass the variables from the Output node to the Postproc node(s), to save some trouble!

Oh, hey, that's cool I'll give it a test later this afternoon!

Do you want me to put together a how-to? I've already got a good chunk of one in my OneNote page.
