Over the past few years, I've been writing scripts for both myself and other forum members. I've slowly been adding them to the Happy Otter Scripts website at https://tools4vegas.com/. Here is the direct link to the Free Tools library. https://tools4vegas.com/library/ At the moment, it's kind of a dog's breakfast of stand-alone apps, script extensions and text scripts that I have written. These tools are available for both Magix and Sony versions of Vegas.
