JPEG batch export to sub/folder structure

I like to realize an export of high-res JPGs from a big sub/folder structure to low-res JPGs in another directory with identical sub/folder structure. Application is the up-to-date providing of thousands of pictures on a NAS as 1920x1080 JPGs for fast and convenient watching on a Full-HD-TV. How can I realize this with MediaPro (MP) or CaptureOne (C1)? My issues are so far:

• With MP or C1 the export files are placed either in source directories or in only one target directory.


• Creation of 2nd, 3rd, ... JPG files shall be avoided. That happens e.g. in C1 during recipe processing if a target file is already existing.


• Skipping export if the target file already exists (or the source did not change) would be nice to have. This would avoid unnecessary updates. That requirement is certainly somehow challenging.


• Is there a good way to process JPG and DNG files in one step or in two steps.


• With DNG files I experienced that MP is just converting the preview and not the raw photo. C1 does convert DNG to JPG of course correctly.
