>>28380601. I take a particular liking to a piece of music and/or motion for it and make a mental note to use it at some point.
2. I feel like creating a MMD video and one of things stored at step 1 comes up in my mind, then I decide to use it. Prior to step 3 I should already have a vague vision of what it's supposed to look like in the end, but not always.
3. If I'm not creating a motion from scratch, I review the motions for it that I have and pick one or maybe more that I like best.
4. I pick the actor(s), background, and extra models/items.
5. I create or adapt the motion to my model and incorporate impromptu ideas. The adaptation part usually includes going through the motion frame by frame and fixing erratic IK behavior, clipping limbs, and unruly physics plus adjusting the camera and taking advantage of my model's extra features, like the advanced foot rig.
6. I choose the effects and settings that would fit the already formed vision in my mind, trying different things or using what I'm used to.
7. I render a lightweight test video to make sure everything works fine at full framerate and fix what isn't.
8. If I'm satisfied, I exit MikuMikuMoving, let the graphics card cool down, launch MikuMikuMoving again, close all or most other executables (depending on how heavy the project is), give MMM real-time priority in Windows Task Manager, open the project, and render a final video in 1920x1080. After it finishes rendering (which could take over an hour), I review it again.
9. Finally, I edit the video in Filmora, adding transitions and on-screen elements such as credits, song title, mosaics in case a lewd bit is visible, subtitles, or equalizer. I might go further and add post-effects like chromatic distortion. I also decide on the final version of the song to use at this point (if I had saved several appropriate covers) and add sound effects.
10. I upload it online and create promo screenshots & write up descriptions while it uploads.
