Yes, we are going to soon implement import of mov and mp4 video.
But already now you can import video as long as it is in the form of a sequence of png files or even an “animated” gif.
Also, you can hear your audio if you scrub the playhead in the timeline below. And you can even scrub from anywhere if you just hold Shift and scrub left/right with your pen or mouse.
Maybe you already knew these things?
