What is the purpose of the video you are discussing? Is it to remind yourself of things you're training on, or as a tool to train others?
To be perfectly frank, I don't think you should just dump your martial arts knowledge onto a video. The problem is if every martial artist does this, what you're going to get are a lot of brain dumps that largely only make sense to the person speaking. I find there are three types of videos that are commonly made, and only one of those three is worth anything as instructional material:
- A video which shows the technique, usually with text illustrating what the technique is and a couple angles of the technique. These videos usually miss the application of the technique, counters, training tips (i.e. what you might be doing wrong), or how to combo with other techniques.
For example, this video might show a few basic punches, and all you get is the name of the punch and what it looks like. You don't get tips like how to combo with other punches, when to use this punch over the others, or tips like "rotate your foot to put your hip into it".
These videos are just a list of techniques and nothing more.
- A video which does the opposite of #1 and includes every single thought the person has. For example:
"This is a reverse punch. When you do the reverse punch - oh, it's a punch with the rear hand - you want to twist your foot and drop your knee. And make sure you don't do a reverse punch and then a jab, because that doesn't make sense, always jab first if you're doing a one-two combination, but if you just need one strong hit use a reverse punch. Now this is a hook punch- oh, right, one more thing about the reverse punch is you want to make sure you use these two knuckles and have your wrist straight. Anyway, the hook punch. This is a hook punch. Notice how I come from the side in a hooking motion. Now, one counter you might see for the hook punch is a block like this. So if someone does a hook punch to you, you can block here and then take them down this way. If someone throws a jab at you, then you may want to block this way instead, but remember with the hook to get your hip into it just like when you do the reverse punch..."
These videos tend to have a lot of rabbit trails, answering of random questions that nobody was thinking of, without orienting the user to what the question is. These are videos taken in one long take, with no cuts or editing, and seemingly no script. Just whatever the instructor thinks to say to cover whatever eventuality might come up.
Both of these videos would be terrible to leave as a legacy of your martial art. The former is bad because then it just becomes a set of techniques with no real connection. The later is bad because nobody's going to sit through an hour of rambling and try to piece together what you're talking about. It's different if the instructor gives you the basic instruction in class and then answers specific questions that are asked, or points out mistakes that are being made. The class may come across like the video, but it's different because it's interactive instead of trying to parse through an hour of rabbit trails.
If you really want to make a video detailing your art's knowledge, you need to approach the video with the same amount of care as you would approach a student. To make a good video, I would
- Demonstrate the basic technique at a speed slow enough to see the details, but not excruciatingly slow (i.e. a punch or a throw at 50% speed)
- Describe the exact motions you are making with the technique and break it down step by step (i.e. the chamber position for the punch, how to torque your body, the turning of the wrist, the tight fist, driving through, and recoiling the hand afterward)
- Cut to a demonstration of applications (for example, targets, and have a slow-motion strike with the punch to various vital parts on the opponent, such as nose, throat, solar plexus, stomach, and groin)
- Demonstrate the technique at half speed and full speed
- Cut to a demonstration of common problems (i.e. bad hand position, failure to turn the body, not following through, or not recoiling) and why those are problems
- Cut to a demonstration on how to safely practice the technique if the technique can be dangerous to practice
- Cut to a demonstration of combinations that include the punch
- Cut to counters to this technique
A video organized like this - with editing and voice-over, with cuts to show we're talking about a different subject - can really help the viewer out. You logically separate each technique by having it as it's own video clip or the next section of the video. Each cut within the technique jumps to the next part - initial demonstration, detailed description, application, demonstration, troubleshooting, safety, combinations, counters. Separating everything logically for the viewer in this way can make it very easy to follow what you're talking about, but also make it easy for them to skip to the appropriate part of the video.
I would encourage making videos if you can produce something worth using, but my experience on Youtube is that most videos are not worth using.
Some things I do well, I am not even aware, it is just the inconscient result of training.
