// Problem happens regardless of duration, but unless using
// the `.velocity-animating` CSS hack it is easier to see with longer durations.
const options = {duration: 1000, easing: 'easeInOutQuad'};

export default function(){
  this.transition(
    // this works
    //this.use('fade')

    // this has a glitch; can see second copy/ghost of modal in top left when closing

ffmpeg -re \
# -re (input)
# Read input at native frame rate. Mainly used to simulate a grab device, or live input stream (e.g. when reading from a file). Should not be used with actual grab devices or live input streams (where it can cause packet loss). By default ffmpeg attempts to read the input(s) as fast as possible. This option will slow down the reading of the input(s) to the native frame rate of the input(s). It is useful for real-time output (e.g. live streaming).
# (!) Turns out this will interrupt the stream by the audio input, making the output stream fps looks extremely low
