The Video Track In the KaraFun Studio Editor, whether for a KFN or a KFP new project, the video track works in the same way. In case of a KFN file, you just need to set the main audio source first. If your video file contains an audio track, you can select it as the main audio source, but in that case, you won't have all the control features of the KaraFun player like Key or Vocal Reducer, etc. Because of these technical limitations, we advise you not to use the audio track of the video files, but separate them into 2 differents files: the video on one side (.avi, .mpeg) and the audio on the other (.mp3, .ogg).

Extract or Remove Audio Track from Video

• Install VirtualDub
• Open your video file in VirtualDub

• Select "Source audio" in the Audio menu
• File, Save WAV... (Note: not necessarily a WAV file, it can be a MP3: it depends on the audio format used in the video)

• Select "Direct stream copy" in the Video menu
• Select "No audio" in the Audio menu
• File, Save as AVI...

Add a video file

• Open the library and add your video file.
You can't linked a video file located on your hard disc to the karaoke file: you must add it in the library.
You can play video since you have the proper video codec installed on your PC. We recommand you to download the ffdshow codec pack.
Supported Video Formats: AVI (DivX, Xvid), MPG (Mpeg).
Unsupported Video Formats: WMV (Windows Media Video), MOV (Apple QuickTime), RM (Real Media).
However, there are many free video utilities that can convert your video in what you want, like RAD Video Tools...
• In the Project menu, click on Add a Track... and select Video. A new video track appear.
If you are sure not to use the background track (wallpapers slideshow), you can remove it: select the Backgound track and click on Remove track in the Project menu.
• Click on the video track and select the video file in the properties (at the top on the right) and play to test...

Video track properties

• Play at start: if you want to start the video later, uncheck this box.
• Seek time: if you want to place the video at one point
• Loop the video: check it if you want to make the currently selected video repeat. Usually checked for KFP preset files and unchecked for KFN files.
• Display last frame: by default, at the end of the video, it'll disappear. If you won't, you can check the box to display the last frame of the video.
• Horizontal and vertical offset: usually couple together with the Zoom option, it allows to move the video position.
• Zoom: this option comes in handy when your video size don't respect the 4x3 ratio! However we recommend you to keep it to 100% and to adapt the video size before in a video editing software like VirtualDub, it's freeware.

Video track events

Like on the other tracks, you can put events and add video effects by changing the properties in order to make some interesting video effects and transitions.

• Change video state: you can play or stop the video at any time and change the seek time if you want to begin the video in the middle for example. By default, when the video ends or is stoped, it disappear. If you won't, you can check the box to display the last frame of the video.
• Change horizontal/vertical offset and zoom: you can change the position of the video during a certain time and with a transition type like for the text track: smooth, linear, falling, bouncing...
