Extract Multiple Selected Motion Data With Frames.cs

// Extracts PiP tracking information to a CSV file
//
// Works with Vegas 17
//
// Based on this script: https://www.vegascreativesoftware.info/us/forum/beta-pin-image-video-to-motion-track--112837/?page=2
// With the help of this documentation: https://walkedby.com/other/VEGASScriptAPI.html
//
// How to Use: (Remember, this is a very hacky script!)
// 1. Select all the relevant track events
// 2. Run the script
// 3. Yay!
//
// Don't forget to change the file name of the CSV file!
