I am using Premiere Elements 15. I simply want to edit video clips to upload to Adobe Stock, such as mute the audio and do some cutting. Elements always creates a project with an extension of "prel". I don't want a project. I just want my edited video to be in the file folder that it was in originally, just like they are when I correct photos with Photoshop. I can't seem to figure out how to do this.
You must have a project, since the project file contains the commands to edit your video file
When you are done editing, you use the share function to create a new video file

Video editing works more like Lightroom's non distructive workflow. The original is never changed. From it you make creative edits and export a new version. Like photographers, video editors want editing tools to make improvements.
There is an exception. Google for "smart rendering video editing software". A few things will come up for reading. I've never tried it, but "TMPGEnc MPEG Smart Renderer" is often mentioned in other forums for what you say you want to do.
