At the moment the system does not support the ability to add tracks in a sequential order or loop existing tracks. Here are some options for you:
A) Upload a longer MP3 file purchased through a stock library like AudioJungle
B) We offer additional tracks in the premium library with a running time of 2:30 - 3:00
We often get requests for a platform that supports the creation of 5 - 7 minute videos which studies show can be quite lengthy and ultimately leading to a massive reduction in overall completion rates. Our system is really designed to encourage the creation of short segments that can ultimately be strung together through the interactive video player we're working on.
