I have a rather puzzling scenario for you, one that I would like to solve with Automator:
We're a startup that creates HD music video content that is streamed online; we've got a custom-programmed Linux/Unix backend that takes HD videos from a folder, processes them for streaming, and throws them up in a Web format so that they can be viewed/streamed/downloaded from our site. Let us call that folder Folder D for the sake of this problem.
When a video editor has a completed project, he or she adds their project to Folder A, Folder B, or Folder C, each of which is a folder on a volume on our SAN. The SAN has 3 volumes, any of which can be mounted RW on one machine at a time, so at any time up to 3 people can be adding content to A, B or C.
What I'd like to do in Automator, if possible:
- Watch folders A, B & C for new videos.
- When a video is dropped into one of those folders, copy it to Folder D.
- Our backend system works on D and then deletes the file from D.
- The tricky part is making sure that once the file is deleted from D, it isn't re-added from A, B or C.
- Because of the SAN's limited RW access, assume that A, B and C cannot be written to from the machine where Folder D is located.
I am basically unsure of how to specify something like "once this video has shown up once in Folder D, ignore it if it ever shows up again" and don't know a way to do that without somehow accessing the originals on A, B & C and renaming them
