Great post. It’s funny that you mentioned powerlifting because I feel it’s related to this subject.
It’s unfair for Andy Serkis to take credit for Caesar because he essentially used performance enhancing visual effects! 🙂
If you were in a powerlifting competition, you would be disqualified for using steroids: It’s a performance enhancing drug that gives you an unfair competitive advantage. We wouldn’t be able to tell whether it was your performance or the work of the steroids that gives you a great performance.
What about a situation like John Hurt in Elephant Man which garnered him an Oscar nomination even though he was in makeup and wearing a mask?
Unlike visual effects which can dramatically alter the performance after the fact, makeup aids and suppliments the actors performance.
The same can be said with the use of protein drinks, weightlifting shoes, etc. These items supplement your performance, but do not enhance it.
I think we should stop using the words motion capture or performance capture. It should be called performance enhancing visual effects.
