Deleting segments

The fewer issues I have to read, the more new features I will have time to implement, so I ask that you please try these things first

• Check out all the menus and keyboard shortcuts. Maybe the feature already exists?
• Try with the newest version from GitHub
• Read the documentation and FAQ, Known issues, Troubleshooting to see if the feature already exists
• See if someone already suggested this under Issues or Discussions

Description

Imagine you want to cut some segments from the video and Export it to one file with or without any marker. I used to do this very easily using the Avidemux program; I just had to mark the in and out and press delete on the keyboard. However, Avidemux can only mark one segment at a time, and they have to be removed one by one. This changes the overall video timeline duration and it confuses navigation by timecodes. I suggest to add a button to invert segments either for export or deleting. Also I missed an simple option to export to 1 file. Moreover, Avidemux has the option to export transcoded audio or video tracks or select an external audio file for muxing. Sometime it is useful. And on Lossless-cut, choosing a codec doesn't help if it's different from the source.
