Compressor watchfolder with multiple tasks

If you don't mind my asking, why transcode the files to ProResHQ? Any transcoding will never add to the quality of your files. ProRes files are more amenable to edit, so if you are to apply lots of effects, color correction, etc, the may stand better than original media, but you get nothing extra by using ProResHQ over ProRes.

In FCP, in just about every case, I just edit with the original files directly. I don't have Premiere, so maybe it won't deal adequately with your media.

Regarding copying files instead of transcoding: this is easy, and Compressor does not need to be involved; macOS has the tools for that. Just add a Folder Action to this folder.

In Automator, press Command-N to create a new workflow, select "Folder Action".

Something like this will be enough - just select the source folder at the top, and the destination folder in the popup (it says "Desktop" in the picture, select the folder you want).

You can certainly create multiple versions of your files in one go in Compressor, and it is actually trivial to do so.

You already have a watch folder, simply add another preset to it.

Here is an example that I just made to illustrate (Note: I have never used Watch Folders in Compressor, but you already dominate that concept, so all that is missing to add one - or more - presets to it)

Thank you for the clarification. In these circumstances I would use proxies. In FCP, as you know, one creates the proxies in the application itself, and we can select “proxy preferred”, then switch to optimized/original for export. I don’t know if Premiere works similarly.
