I made a simple demo toggling between white and black screens and having the 440Hz middle A tone going on/off. I will include the source files and the final exported .MP4 to demonstrate the problem I have whenever writing any audio in my exports.
MAGIX Movie studio 2025 Suite
Version 24.0.1.199 (UDP3)
UG code 8485 KA1
Windows 11
What email address can I upload a .ZIP file to with the source code for the project I am having trouble with?
