First, choose an anime with a great love story. For example, 'Fruits Basket' has a beautiful love story with many emotional moments. Then, select a song that fits the mood of the love story, like a soft ballad. Next, start looking for key scenes in the anime that show the development of the relationship, such as the first meeting, the confession, and the happy times together. Use video editing software to cut and arrange these scenes according to the rhythm of the song.
The appearance of a science fiction story on AMV is unpredictable. It could be anytime based on factors like the creator's inspiration, available resources, and audience demand. So, you just have to keep an eye out for it.
