I want to edit 4k/5k videos but my computer is not powerful enough to edit those videos. Are there GoPro video editing sites/ programs where I can upload videos to the site and edit them without needing a powerful computer?

If you use a MAC, and the video files are saved to a remote hard disk, iMovie does NOT import the files when you edit. You edit what could be called a reference file (super fast) and only render a file for export when you have finished editing. That is the only time you really need to be concerned about computer power, and it doesn't matter at that point whether the process takes one minutes or thirty - does it?
