Advanced Compositing Tracking And Roto Techniques With After Effects is a video workshop presented by Jeff Foster – award winning video producer, compositor, visual effects artist, and author of The Green Screen Handbook in which he guides you through some more advanced aspects of green screen compositing and working with a Roto workflow with After Effects. If you are new to compositing, you may want to check out his earlier title Fundamentals Of Compositing Tracking And Roto Techniques With After Effects

The goal of this training is to provide you with real-world techniques for getting the best mattes and keys from your green screen shots using more advanced techniques and working with more complex compositing. You will learn how to be more effective with your use of the Roto Brush, see how to do match moving, work with matte painting, as well as other techniques to create much more believable composites. There are also some third party add-ons that are used that are available as free trials.

Advanced Compositing Tracking And Roto Techniques With After Effects is presented in high definition video and breaks out into 5 chapters and 16 videos that runs 2 hrs. and 10 minutes in length. Included as well is all of the footage and assets that are used in the training for you to work with on your own.

Advanced Compositing Tracking And Roto Techniques With After Effects

Chapter 1, “Roto-Painting Techniques with a Wacom Tablet,” begins by looking at the Roto Brush and how it can be used to mask out areas in a film segment with the use of a Wacom Intous 4 tablet. This technique is handy when you don’t have green screen available or the green screen footage that you had was poorly created. Although the Roto Brush does a good job of masking, you still may need to perform some additional cleanup. You will see how this can be done through the use of the eraser tool.

From there you will now look at refining the details. Here you will get several tips and tricks that will give your scene a greater sense of realism. You will see how you can add motion blur to make your scene more convincing. Finally you will see what you can do when you overwork a scene and you need to go back in time and change something that you did earlier in the sequence.

Chapter 2, “Complex Composites: Multiple Keys,” now looks at the use of both green and blue screen sandwich compositing. It starts off with a video that is a bit off kilter with the background and you will see how to realign it make it all match to the scene. Then you will see how to fix some detail problems with bleed through by using a second pass in the problem areas. Finally you will learn how you can work a bad green screen clip – where the screen was not lit properly and moving hair makes it more difficult to work with. Here you will see how to work with multiple layers, masks, and Roto painting to fix it.

Chapter 3, “Motion Tracking and Match-Moving,” starts off by showing you how to track a camera’s motion so that when you can replace the green screen the movements to a static background will seem natural. The footage here has some problems with the tracker points and you will see how to work with this kind of situation. The footage used here is of a Christmas tree near an outside window and the outside has been green screened.
