thats some code that works up to 1 minute. If i take the exact same structure and put it in the playground but take out that last entry the audio will not be put into the file. Can you tell why?
Again the audio is only 47 seconds.
Below is the code to test if you want which will not render with audio. all i did is take out that last clip entry
