When I started making the seamless FMVs for Eric the Anteater, I would render them as a series of frames and import them into the sprite editor, one by one, manually. It was tedious and took a lot of time. I then later realized that with the "quick import sprites" option one can simply select a block of images to import and there you have it. I must have wasted several hours over the last few months. Boy do I feel like an idiot.
