Make one point and one point only. If you make multiple points in a video, that may make the video a little more confusing. So just break up that video into two videos where you make one point per video.
Different types of courses call for slightly different video lengths, but there are still many rules of thumb you can follow.
1) Definitely stay away from videos over 20 minutes long. If you have a video that long, you may have either gone on numerous tangents, cover more than one point, or speak too slow with too many parasite words like "ummm" and many others.
2) Preferably keep the video under 10 minutes and if you can under 5 minutes.
When I watch my own videos, I notice that my mind can wonder more or less from video to video. Even though watching my own videos is extremely boring, it's a necessary test just like you would test any other product you made.
Surprisingly, some of my own videos don't bore me and keep me captivated. Those are videos that stay on point, aren't confusing, and in which I speak in an interesting way. On the other hand, when the videos are confusing and lose me as a listener, I wonder to myself how I can make such bad content and am almost disgusted with it.
My goal is to keep the videos under 6 minutes in all cases and preferably under 5 minutes. If a point I am making is not complicated, the video can be 2-4 minutes. If the point I am teaching is technical or complex, the video can get up to 10 minutes. But that is rare and I try to avoid it.
In a video that is few minutes long, you can easily introduce a new idea and give an example of it. You can spend another minute or two giving another example, but after that the video will start becoming a bit too long and it will become a case of "more is less."
