This is a simple script to combine two of a video file's audio tracks into one. It doesn't impact the video's quality.
To make things even more simple, it only prompts for an input/output video using file selectors. The rest is handled automatically.
This is a simple utility to rapidly "fix" videos with split audio tracks, such as those recorded by ShadowPlay or OBS.
To use this script, simply copy/paste the "merge.ps1" code below into a new file named "merge.ps1", then launch it.
