I'd love to contribute but I have jack shit for recording equipment besides you know, a microphone. Unless you want camcorder of a tv haha.
As a suggestion/query, do you intend to make this centered around players new to fighting games or those who have a basic background or what. If you decide to aim for the latter, I suggest that you change the predicted format, to something that focuses more on what's unique to the game.
More or less people that have a simple to moderate background in fighting games. Basically, people that play other games already.
What did you have in mind?
Well basically, if you want to focus on those who understand fighters, I don't think there's a real point to outlining stuff specifically about combos/blocking and the like. I'd personally suggest that if you're directing it to people who grasp basics that you'd dive straight into the most important parts of the game. I think it's overly ambitious to aim to cover all game mechanics and system parts and expect even just people interested to sit through the whole thing. Maybe you could split the videos up?
For example, after your initial opening and introduction to the game, bring out some comparisons in what it does have similar (chaining, "groove" system, otgs etc) but then outline the things that are unique to Melty. The important thing to understand when you play this game is the basic way to approach the game at first. So start off and show people how movement is used in a unique way for footsies and rushdown (iads, aerial sidesteps, DI in the air, aerial superjumps etc), and then move onto what happens when somebody gets aerial ch'd (show the use of reverse beats and whiff cancels in creating frametraps and the like for mixups, show iading to reset as well), and then show what the person defending can do against it.(Bunkering, Heating, Circuit Sparking, Shielding, etc) Whether or not you need to cover the actual mechanics beforehand or explain them on the go in this would depend I guess.
At this point, a viewer will now understand at least how a match is meant to happen. You can then get into more technical things but focus on universal stuff to apply, like knowing the differences between the grooves and go back over how the gameflow is affected by your groove choice, the way crossups work, etc. Build on it from there etc. But basically
stick to what makes Melty, Melty, don't get too caught up in stuff people probably already know about unless you are purposely reaching for complete noobs.
