Andy Shipsides with AbelCine has written a great article about 24 fps judder: it's causes and how to deal with it. The article appears in the February 2012 edition of HDVideoPro, and he sums up the issue very well. He also mentions the Time Filter in the article as a way to deal with the issue. Check out this excellent article if you haven't seen it on page 26.

Andy contacted me last year as he was researching the topic, and I was very impressed with his technical and practical grasp of the situation. Great article!
