The easiest way to migrate content from Zoom to Panopto is to download from Zoom, and then using the "Create" button and choose the "Add Media" option in the Panopto folder you wish to add to.
You can drag a copy of all the relevant MP4 files into the window and this should upload and process them for you.
As always it would likely be recommendable to rename the files so that they are easily identifiable and contain a short description so that Students can distinguish what they are.
