Small Windows program to automate drag-and-drop

Hi. This might be a slightly weird one. Some of you might be familiar with the LG 360 Camera, and its Cam Viewer software. In brief, the 360 Cam shoots dual fisheye videos, that need to be converted by the program, that happens by dragging-and dropping the file into it, it then converts (stitches) it to the proper equirectangular video format. BUT... The problem is it only accepts one file at a time, and converting them one by one takes a lot of time. As I failed to find another converter program, I'm thinking maybe this could be automated in a way, that when the Viewer is done converting one video (and automatically starts playing it), a small app could somehow detect this and "drag-and-drop" the next file into it from a given list (even if this means I need to position the side by side on the desktop or whatever). I need to convert a lot of files, so it would need to accept a list (maybe I give it 5-10 files at once, depending how much time I have), and should be pausable or stoppable, have some practical functionality. Any solution is acceptable, even different from what I suggested - You as a programmer might have a better instant idea or solution, might be able to use the resources and libraries of the actual Viewer, etc. I just need to be able to automate this somehow. Looking forward to your suggestions.
