I’ve figured out how to create a template in Shotcut (which I’m defining for our purposes as a video with certain reoccurring elements – an opening, music, closing, etc so you don’t have to keep remaking the wheel, so to speak).
First, assemble the elements that will remain consistent from video to video (music, jpgs, and whatnot) and put them in their own folder.
This folder is important, and once assembled, should be left alone.
Then build your video from the elements in the folder ONLY.
It will not be “complete” in that it only includes what you need to produce the skeleton of your video, including whatever else you want to remain consistent minus anything that you don’t want to remain that way.
Save it and call it something fairly obvious (and simple. This is not the place for cleverness).
Let’s say you’re ready to use the template. Open it and start building your project, using the “Save As” command, NOT “Save” and changing it’s name to whatever it is that you’re currently working on.
Close the template (deleting any additional files if you added any) then open the file you just created with the “Save As” command and use how you will.
The point being the file you designated as a template will remain pristine, and you won’t have to keep remaking it.
This may have been intuitive for some, but coming from Final Cut Pro X Shotcut is a whole different animal.
