Convert MIDI karaoke to video (AVI)
The video files music are always in audio format (WAV PCM, Mpeg Layer 3 MP3, etc.) never in MIDI format. To convert a MIDI karaoke to video (AVI), you must convert the MIDI music source in MP3 or WAV audio first.
Solution 1
Without going through KaraFun Editor, convert MIDI music source in MP3 or WAV audio to be able to convert MIDI karaoke to a video (AVI).
1. Convert your MIDI karaoke to video without audio
In the karaoke library, right-click on the MIDI karaoke file you want to convert and click on "Convert karaoke to video (AVI)". Choose export options (format and video compression, display options) explained in the other pages of this help, and start the conversion. Thus, you get a AVI video file without audio.
2. Convert the MIDI music to WAV
Note : if your karaoke is a KFN file (based on a MIDI file like KAR or MID), you must extract this file from the KaraFun Editor library first.
- Download, install and run SynthFont
- Open your MIDI file (.KAR or .MID) from the File menu (if you don't see your file, choose "All files" at "Type files"
- Click on the "...To File" icon and save your .wav file
- Click on the Play icon and wait the end of the song who must be fully played to be converted
- When the conversion is done, you can exit SynthFont.
Note that you can change many parameters with SynthFont like the instruments of the MIDI channels, panning, volume, etc.

3. Add Your Voice (optional)
If you have recorded your voice with KaraFun, and you want to hear it on your video, you have to mix both WAV files (music + your voice) together:
- Locate the WAV file of your voice recording. According to your KaraFun options (see Audio/MIDI tab, "Voice recording" part), the .wav file is either in the folder C:\Program Files\KaraFun\Temp, or in the folder of your karaoke, or in a folder you specified.
- Download, install and run Audacity or any audio editor. We recommand you Audacity because it's free and easy-to-use.
- Drag and drop your WAV files on 2 different tracks, check their synchronization and adjust their volume: in the example, music has been lowered of 9db to bring out the voice (red circles). To care of saturation!
- Export in a new wav file from the File menu, and exit.
