Ivy's Sonata of Temptation: Plagiarism

This is the music video for Ivy's Sonata of Temptation:

This is the portion of Final Fantasy VII: Advent Children it was clearly inspired from:

Square Enix, makers of the Final Fantasy game took the video production company to court. The video's director, Hong Jeong-ho, claimed the video as being merely a parody, which Square Enix (and ultimately the court judge) disagreed with. In the end, the video production company Fantom was fined $10,900, while both Fantom's director and the video's director were fined an additional $6,500 each. In the United States, the copyright infringement fines would have been many times that.

Now, as plagiarism in writing is clearly now very easily detected, as media gets more complex, will we see a similar shift in plagiarism or will it simply be too complicated to monitor and too easy to modify into the broad category of parody for such purposes? (For instance, I don't see people re-shooting Star Wars shot for shot with their own costumes on YouTube yet)
