Frame by Frame Animation for Film

I need frame-by-frame animation for some scenes of my experimental short anti-fashion film. The animation will be drawn over flowing video. There are 2 still images and three short scenes. I'm waiting for the animations to be done for the film's sound and credits, as the animations will also have sound effects. Therefore, it would be much better if I received the output as a PNG sequence or another alternative if you have one, so I can add it to the high-quality version of the film later. I will send you a Drive Link with sample drawing styles and the animation script (and whatever else you need). The film is a short story about a couple who believe the world is ending. The woman believes it will happen through clothing tearing, and the man through nuclear explosions. They have an isolated but quite colorful life. Absurdly, they call people outside to prepare for the end of the world. It's a fashion film, but an anti-fashion film. You can go as far as you want with the colors.
