Join Ian Robinson for an in-depth discussion in this video Tracking a spiral, part of Mograph Techniques: Retiming and Tracking Footage.
I was very happy when I first saw this clip because I knew we could create some…pretty dynamic particle animations flowing off the back of the football.…But before we begin the process of tracking the football, I want to show you…some technical considerations we need to look at.…Move the current time indicator to frame 10, and you can see the football is…extraordinarily blurry. Also, I don't have much separation between…the football and its background. This alone is going to make this rather…problematic to track. Now, usually, I would use a planar tracker…like Mocha to try and track an abstract shape like this.…
But I've already gone through that process, and just like I thought, it was…very problematic. So, instead, I'm going to show you a real…world workflow. See, when you're working on a deadline,…you need to kind of balance whether it makes more sense to optimize a tracker or…optimize the footage for a tracker or just manually track the footage.…And if we look at our clip, you can see that I've only got 23 frames of tracking…
