Editor to transcode minus commercials

I'm looking for a simple, low cost, editor that will allow me to manually mark commercials and other undesirable crud for removal and then transcode the recording. Any suggestions?

What platform? On the Mac, I’m using Lossless Cut to mark in and out points, and cut them, but I think you can also mark other places in a recording.

That might be helpful. Windows 11. I tried Hitfilm free but it won't import files from Channels and HDhomerun Prime.
