Final Cut: “Selection contains no media”

I encountered this error while trying to export a video from Final Cut using Compressor. Obviously my sequence did in fact have clips in it, but I didn’t see why this was occurring at first.

Somehow, the “in” point had been set to the last frame of the main timeline, so essentially I was trying to export 0 frames. The solution was to clear the in and out points by right clicking on the timeline of the sequence.
