Is there a way to do karaoke with this program?

What’s the file format of the videos?

vjay supports H.264 and MPEG-4 video up to 1080p, 30 frames per second in .mp4, .m4v and .mov file formats.

Sorry, I’m afraid I’m not too familiar with that. Maybe with iMovie?

whats the easiest way to convert an mp3 plus graphic file to get it to mp4 for a video in Itunes
