TIMECODE
00:00 Intro
00:28 Prerequisites & Setup Learn:
About the network setup and parameter adjustments needed to follow
long effectively.
01:00 Network Overview:
A brief review of the different sections within the TouchDesigner network,
including video input, time machine, control, and blob sections.
01:32 Blob Creation & Data Extraction:
Focuses on creating blobs and extracting their information for instancing
3D objects or text.
02:31 Key Concept: Data Extraction:
Understanding how to extract coordinates from blob tracking to create
instances or apply to text operators.
02:58 Blob Track Top Inputs Explanation:
Of the two main inputs of the blob track top: the color image and the
background reference frame.
03:57 Extracting & Using Tracking Data:
How to extract and utilize the blob tracking data stored in a table data,
including UV coordinates, width, height, and age.
04:57 Applying Blob Tracking Data to 3D Instances:
Processing blob tracking data using chop operators to manage and
manipulate information for creating 3D instances.
07:24 Understanding Aspect Ratio Calculations:
Learn why adjusting for aspect ratio is crucial to prevent distortion of
instance positions when changing resolutions.
09:35 Positioning Text Using Blob:
Tracking Data Using absolute pixel coordinates in top operators like
the text top to position text based on blob tracking data.
12:03 Time Warping Explained:
Introduction to the texture 3D and time machine operators and how
they are used to select and display specific video frames.
14:39 Verifying Time Machine:
Frame Selection How to verify which frame the time machine is showing
based on the color of the source image by checking pixel values.
15:09 Creating the Pattern:
Animation for Time Warping Learn how the grid SOP and ramp operators
are used to create the tiling animation for manipulating the video with
the time machine.
