Hey! I'm not really familiar with either one so take this with a grain of salt. On the first glance, it doesn't seem like these projects are designed to be run in the browser. We're mainly focussing on the use-case of using Revideo as a part of web-apps (we're building on top of the HTML canvas API which makes it really easy to preview instantly). There might be some use-cases where a lower level implementation is more suitable.
