https://superuser.com/questions/681885/how-can-i-remove-multiple-segments-from-a-video-using-ffmpeg
I was trying to do the above with ffmpeg, but without re-encoding. I currently can do it by using each command separately i.e.:
    ffmpeg -ss 00:00:00 -i input -to 00:00:00 -c copy output 
And then I'd concaticate the pieces I want together.
I looked up how to find the nearest i frame to try and get more accuracy when choosing times. But putting all this together and checking the video after getting each piece of information...turned into a very inefficient process.
So I wanted to know if there are any gui (video editors) that support this functionality of ffmpeg in a more manageable manner. I mean the simplest and ideal process I can think of is: I toss the videos in the editor, i click an option to disable re-encoding, i choose the sections I want. Then it just chooses the nearest i frame to my cut choices (if it displayed the i frame that would be good too) and does all the above stuff.
I don't have much experience with the modern capabilities of video editors. The ones I have used have very limited functionality when it comes to rewrapping/'no-encoding' compared to ffmpeg command prompt, or just always re-encode to begin with. So I'm just curious if there are editors that have the kind of re-wrapping functionality that ffmpeg command prompt has. Otherwise I'll need to pursue the solution from a scripting perspective, of which I know nothing about.

DVDVideoSoft makes a tool called Free Video Editor. It is free, but certain features are only available to premium users who buy a license. Free Video Editor can cut out scenes without re-encoding when using compatible formats such as H.264. You can export as a single file, or individual pieces. This feature was free (up until at least version 1.4), but is now only available to premium users.
MP4Splitter (part of MP4Tools) can be used to break an MP4 into multiple parts, and MP4Joiner (part of MP4Tools) can be used to join the parts you wish to keep. It is free.

FFmpeg GUI for Linux & Windows

I was looking for something to trim specific clips from my dashcam videos.  A lot of the "free" programs I found were trial versions or came with extra baggage.  When I realized that FFmpeg was a reputable engine that was capable of doing all the work, I decided I wanted to find a solution that worked with it.
I have very limited experience with FmpegYAG, but I was able to get it working after a few minutes of testing.  I can visually cue the onscreen video to the beginning and ending of the clip I want encode.  If you preview the video it will show a red "X" over the video that you have selected to exclude from encoding.
I like that it can generate script files.  That allows me to see what commands it is sending to FFmpeg.  They script files have an extension of .cmd but are equivalent to .bat files.

Note that if you select copy as the Video Codec, the encoding is extremely fast.
