I've been chipping away at an Ace Attorney Investigations animation for the past few months, heavy spoilers warning but otherwise CLICK THE BLUE TEXT TO GIVE IT A WATCH!
Some parts of the process below (spoilers again)
I first got the idea to create this when I tried to look up ace attorney rolling girl, I was astonished no one had made one yet and decided it was time to take matters into my own hands. I listened to the song in the car and imagined over and over how badass a AAI version if it would be. Above is the notepad plans of who shows up when and with who.
Miles has a simple design, but since everyone else has a relatively complex design, I decided to make a character sheet where I chibi-fied them ahead of time so I didn't have to do it on the fly.
If I'm honest, Kay had the hardest design to simplify since I would be drawing her over and over again the most... my boldest decision was keeping the key in her hair in detail, definitely the biggest struggle was figuring out the physics of the dangling bits and angle of the key. Everyone else, even if they're more detailed, I drew fewer frames of.
While trying to create the chibis, having the gallery in Investigations was SO HELPFUL thank you to the AA staff for including that in the game.
If you're wondering how I got the frames I painstakingly slowed down the og rolling girl vid to 0.25 speed and took screenshots of every frame so I could trace over it… Not the most efficient method but I couldn't find a complete set of images for it online!! I used Rolling Deltarune as a guide for the animation since the og doesn't go up to 3 minutes.
I use clip studio paint to draw and a small wacom intuos as my tablet... I edited it all in Adobe Premiere, wouldn't recommend but it's what I was familar with eto bleh.
Anyways I hope Santa brings me a gold heart locket so I can rotate in characters I like who will give me strength throughout the day, I'll try to answer any other questions in the replies! ^_^
