Technically they could be the same video, however, if you're chosen to be one of the three performers your video has to be at least 3 songs in length. I personally would use an already made video or SoundCloud track or similar. Look at it like you're trying to get a gig at a bricks and mortar music venue and you send them your pressing kit. In this case a whole press kit isn't needed to audition, just a sample of your music. But if you wanted to submit an entire set worth of music for the audition, that would be fine with me
