First off, what type of videos do you make, and don't say gaming, cause there are so many types of gaming videos out there that it would take forever to explain how to make and edit every type of gaming video. For me, I make funny moments, which has actually been getting more and more popular lately, and they are pretty simple to edit, unless you're like me and get an effect in mind, and spend 3 hours trying to perfect it. Personally, I record audio and video separately, put both onto the timeline in my editor, sync the two up, cut up the video into the clips I want, which normally takes around 1.5x the length of the actual recording, and then start randomly dragging the tracks into different parts of the video, based on whether they all are part of one joke, or on how funny they are. Then, I start adding subtitles and adjusting the audio levels for all the clips so that nothing is too loud or too quiet. Then, I add music and re-adjust the audio, which normally doesn't take that long but helps me catch any other steps I missed. Finally, I add any special effects or animations that I want into the video, which I normally mark where I want them with markers. It's a long process but very worth it. If you want to make funny moments videos, however, I highly recommend that you watch other YouTubers who do the same thing. I would recommend KryozGaming, Smii7y, Fitz, and SovietWombie because even though they all have different editing styles they still all make the same type of content, and you can see examples of how to edit certain clips.
