If I'm trying to edit relatively simple videos, what is a good editor that has these features available on Windows?
- trimming video clips, playing one video clip after another (basic functions, not required but would be nice)
- ability to insert images or audio at arbitrary points on top of an already existing clip, like an overlay (required; this is the focus of the question)
- ability to overlay video as well would also be nice
- previewing the video before exporting it (ability to play/pause video to find places to insert things)
- preferably free (this is somewhat important, low cost is ok too) and relatively straightforward to use (less important)
- anyno specific codec required
