CDG + MP3
The classic karaoke format. CDG contains the lyrics graphics, MP3 has the audio. Used by most professional KJs.
ZIP Files
CDG + MP3 bundled in a ZIP. KaraokeFlow extracts and plays them automatically.
MP4 Video
Karaoke videos with lyrics baked into the video. Works with both VDJ and VLC.
Streaming
VDJ supports DigiTrax streaming. VLC can play direct video URLs.
File Naming Tip
KaraokeFlow extracts song metadata from filenames. For best results, name your files like:Artist - Song Title.zipArtist - Song Title (1985).cdgArtist - Song Title [1985].mp4
The year is optional — if included, KaraokeFlow uses it to populate the decade filter so singers can browse “80s hits.”
