So one of the big problems with my plan to film a short play in Animal Crossing is that there is no way to hide the HUD of the in-game camera. This means all the video you shoot will have the UI in it and will make what you shoot look like it was shot through a camcorder which doesn't always work for what you want to convey. So I made myself a proscenium arch template that I can composite with the game footage to hide the game's HUD in a way that will actually enhance that you're watching a play shot in Animal Crossing.
Oh! And also feel free to use this for any video fun you're planning to shoot in Animal Crossing.
