An app that runs on browser that helps you to make video. SUPPORT please (1 month work spent)

It was hard for me to make some easy stuff, like zoom in and zoom out, I didn't know how. I made it by myself and javascript. SUPPORT PROJECT, I've spent a mont to make it, now it's for those who knows how to download repository from github.

I recommend YOU to use also OBS for recording screen
and Shotcut for basic videoediting
