I'm a graphic designer based in Belo Horizonte. I'm going to present a visual identity and I would like an animation of the brand being "built", about 3/5 seconds. The reference is the assembly of this Itau brand: In the brand that I am going to present, the vertices of some letters were also edited for angles and the idea would be to demonstrate this in the animation. I have a frame by frame of what I thought, but it is in this style of the camera going through the typography customization details and then zooming out the lines passing through the brand and "cutting" the points that were edited to result in the final composition. It would all be flat, just like in Itau, without gradients, without 3D. As it is the presentation of a brand that I
