A feature is a clearly distinguishable visual shape in your clip that represents a fixed location in space. The 3D Camera Tracker works by analysing your footage frame by frame and detecting features that it can track. How the 3D Camera Tracker Worksīefore we look into why the 3D camera tracker does not work, we first need to understand how it does work. I have a full tutorial on how to use the 3D Camera Tracker in Adobe After Effects as a part of my 3D Integration VFX tutorial series.Īs great as the 3D Camera Tracker is, there are a number of common problems that people encounter when trying to track their footage and this tutorial will explain what is going wrong and how you can fix it.
Assuming the tracking data is spot on, you can then place other visual elements in the 3D space of your scene and they will follow the movement of the camera correctly. With part two of the tutorial, Martin continues showing how to import the footage, 3D tracking data from Mocha, and creates a 3D Card in Nuke which will be used for the set extension.The 3D Camera Tracker in Adobe After Effects is a powerful tool that lets you analyse your footage and extract information about the movement of the real life camera used to film the scene. Once the shot is tracked, Martin shows how to export the tracking data, providing some tips on FBX settings for best use with Nuke. Tracking Strategic areas of the shot will help the 3D Camera Tracker in Mocha solve for Parallax. This is a great look at using a mix of techniques in Mocha to track, starting with unlinking a spline layer to attain continual tracking information from a section of the shot, and then relinking the layer so the spline will move along with the recorded track. Using a shot that has some parallax in the scene, Martin shows how to get a parallax solve using multiple layers in Mocha providing more information for Mocha to work with. Imagineer Systems Product Manager Martin Brennand takes you through setting up a camera solve in mocha Pro, then exporting to FBX Demonstrating how to track in a city shot into some footage, Imagineer Systems Product Manager Martin Brennand walks through using Mocha’s 3D Camera tracker and apply the 3D information to a 3D card in Nuke.
