Creating an instagram VIDEO Template

Greetings, We're looking to revamp our Instagram page: [login to view URL] The first step to accomplish that is to significantly improve the regular Instagram videos and make them more engaging than the current ones. Guidelines: 1. Video dimension of 1:1 2. Resolution of 2000x2000 or more 3. The template will allow us to determine the length of the video, it can be 15 seconds long, or even 2-minute long, and the template will support both. 3. The project file will be usable on Adobe After Effects CC [login to view URL] About the graphics : Here is a video exemple of what we're looking for : [login to view URL]) Please do NOT copy/paste the same colors / designs / assembling. On the other hand, we would like to have "kind of" the same Audio Waveform technic (we like that it get stick to the image). And we want to be able to change this image regarding our instagram posts. Please bear in mind that the template should be made in a simple way, so people who has basic understanding of After Effects can use it. No plug-in used. Thank you!
