For more information please see section [Using duet events](https://docs.powerkaraoke.com/link/15#bkmrk-duet-event). ***Advanced duets*** Karaoke Video Creator version allows to create professional parallel duets. The most important features are: [Duet Wizard that helps to assign lyrics to singers](#Duet_Wizard) [Full duet synchronization mode](#Full_duet_synchronization) [Divided screen for duets (Singer 1 at top and Singer 2 at the bottom of the screen) with separate settings for each of the singers](#Duet_settings) ![](https://docs.powerkaraoke.com/uploads/images/gallery/2024-06/embedded-image-j4ouubed.png) Please note that in tutorials section you will find [Create song with duets tutorial](https://docs.powerkaraoke.com/books/karaoke-video-creator-user-manual/page/create-songs-with-duets "Create songs with duets"). ***General remarks*** In duet mode Karaoke Video Creator divides the song in three modes: parts that are to be sung by Singer 1, those to be sung by Singer 2, and parts of the song sung together by both singers. Parts sung by both singers are displayed in the same manner as the lyrics in non-duets song. But when Karaoke Video Creator finds duet part, it divides the screen into two parts and displays lyrics for singer 1 at the top, and lyrics for singer 2 at the bottom (see image above). To enable duets in Karaoke Video Creator use **Full duet mode** toolbar button (![](https://docs.powerkaraoke.com/uploads/images/gallery/2024-06/embedded-image-rhvg96rl.png)) or select **Enable full duet mode** from synchronization menu. ***Non-split duets*** {{@220}} ***Multiple languages*** Full duet mode can be used to create song in two languages. ![](https://docs.powerkaraoke.com/uploads/images/gallery/2024-06/embedded-image-ue37h94u.png) Please see `brother john two languages.pk2` file located in `Examples` subdirectory of Karaoke Video Creator directory (usually `C:\Program Files\Doblon\Karaoke Video Creator` or `Documents\My Karaoke\Karaoke Video Creator  Examples` on Windows 7 or Vista). --- ##### DUET WIZARD Duet Wizard allows to assign portions of the lyrics to each of the singers. {{@216}} --- ##### FULL DUET SYNCHRONIZATION {{@218}} --- ##### DUET SETTINGS {{@219}} # Using CD+G events Karaoke CD+G Creator gives you the full control over the karaoke video you create. You may change the text properties, colors, and display images anywhere in the song. These extra options are available by the means of events. Event is executed after the preceding word is painted or highlighted (it depends of the event, eg. Clear screen is triggered after highlighting, while Colors event during painting). This behavior may be changed for Set Background events, for which you may choose exact time of activation. You work with events in the lyrics editor. They are displayed as boxes with text describing the type of the event.

[![image.png](https://docs.powerkaraoke.com/uploads/images/gallery/2024-12/scaled-1680-/X1cimage.png)](https://docs.powerkaraoke.com/uploads/images/gallery/2024-12/X1cimage.png) Below is the list of events available in Karaoke CD+G Creator. Please remember that some of them are available in Pro version only. After you select the type of the event another dialog box is displayed that allows to set the properties of the selected event type.

[Duet](#Duet_evant) Allows to change the coloring of the text to visualize the change of a singer ![](https://docs.powerkaraoke.com/uploads/images/gallery/2024-08/embedded-image-1svzuzpn.png) In Pro version duets can be parallel
![](https://docs.powerkaraoke.com/uploads/images/gallery/2024-08/embedded-image-nberaoqx.png) [Overprint Image](#Overprint_image) Allows to display the image anywhere on the text. It may also be used to erase a part of the screen
**![](https://docs.powerkaraoke.com/uploads/images/gallery/2024-08/embedded-image-icdkapfu.png) **[Set Text Area](#Set_Text_Area_event) Using this event you may display the image and the text on screen at the same time. It also allows to change the portion of the screen that is used to display the lyrics

Events can be edited. **To edit an event** double-click it in the lyrics editor or right-click it and select **CD+G Event Properties** command from pop-up menu. Events can be deleted like other text. There is one more editing feature available for events -- you may copy event and insert it in some other place in the song. to do this right-click an event to copy and select **Copy Event** command. Now right-click in the place you want the copy of the event to appear and select **Paste CD+G Event** command from pop-up menu. --- ##### CLEAR SCREEN EVENT {{@223}} ![](https://docs.powerkaraoke.com/uploads/images/gallery/2024-08/embedded-image-acsp6nkp.png) If scrolling display mode is selected, after clearing the screen lyrics will painted from the top of the screen. --- ##### COLORS EVENT {{@224}} With Colors event it is possible to change the sweep mode from highlighting text to highlighting the text outline. To do this select the same color for normal and highlighted text, and then select different colors for normal and highlighted effects. Also make sure to enable Outline text effects in **CD+G Settings** dialog box. Due to CD+G format limitations (only 16 colors can be used at one time) if you use too many color changes on one screen you may experience problems (you will not the colors that you want). We advice to use no more than 6 color sets with disabled effects and no more that 3 color sets with enabled effects. ![](https://docs.powerkaraoke.com/uploads/images/gallery/2024-08/embedded-image-1azc4hi6.png) Color event needs to be used cautiously if you choose to display image using *Set text area* event, as the maximum number of colors on screen is 16, and usually image uses up to 10. With one color for background and one for border this leaves 4 colors for text -- that is 2 color sets with no effects and only one with effects enabled. --- ##### COUNTDOWN EVENT {{@225}} --- ##### DISPLAY IMAGE EVENT Display Image event allows to display the image on the screen. Before the image is displayed the screen is cleared. The image will be displayed immediately after the last word before it is highlighted. ![](https://docs.powerkaraoke.com/uploads/images/gallery/2024-08/embedded-image-g6kam1hw.png) In Pro version you may modify this behavior with **Synchronization** settings. [![image.png](https://docs.powerkaraoke.com/uploads/images/gallery/2024-12/scaled-1680-/jwJimage.png)](https://docs.powerkaraoke.com/uploads/images/gallery/2024-12/jwJimage.png) *Note: CD+G image format is 288x192.* Images may be of any size and color depth, however if they contain more than 16 colors or are larger than 288 x 192, they will be automatically converted to CD+G format. If you would like to use an image editing software to decrease the color depth and resize the images, make sure you save them as 4-bit BMP file. {{@226}} ##### ***![](https://docs.powerkaraoke.com/uploads/images/gallery/2024-08/embedded-image-tzvaeaky.png) ****Synchronization (Pro version only)* By default the image will be displayed immediately after the last word before it is highlighted. It is possible to define the exact time when it should appear (but remember that image needs to fit between the previous and the next word). You may define the exact time the image should be visible (**From the start of the song**) -- the value in **Display at** box is a position in seconds. You may use **Copy from cursor** button to enter current cursor position into **Display at** box. You may also define time before the next word is highlighted (**Before the next word**) or after the previous word finishes highlighting (**After the previous word**). Please remember that the time position refers to the moment image is fully painted. It does not include painting nor erasing time. --- ##### DUET EVENT Duet event allows to change the current duet mode. In regular version of Karaoke CD+G Creator duet mode changes the coloring and alignment of the text to visualize the change of a singer. ![](https://docs.powerkaraoke.com/uploads/images/gallery/2024-08/embedded-image-fpvetyju.png) In Pro version with full duet mode enabled duets can be parallel. The upper part of the screen is taken by Singer 1, and the lower by Singer 2. The lyrics for each of the singers are highlighted independently. Please see [Creating duets](https://docs.powerkaraoke.com/books/ai-karaoke-cdg-creator/page/creating-duets "Creating duets") section for more information. [![image.png](https://docs.powerkaraoke.com/uploads/images/gallery/2024-12/scaled-1680-/fLQimage.png)](https://docs.powerkaraoke.com/uploads/images/gallery/2024-12/fLQimage.png) All words after the event will be colored according to the selected mode. Three duet modes are available: · Singer 1 · Singer 2 · Both You may view and change the predefined coloring and alignment assigned to duet modes by clicking **Duet settings** button. [![image.png](https://docs.powerkaraoke.com/uploads/images/gallery/2024-12/scaled-1680-/D7bimage.png)](https://docs.powerkaraoke.com/uploads/images/gallery/2024-12/D7bimage.png) **Mode** allows to change the duet mode that you would like to modify. Only Singer 1 and Singer 2 modes are available -- for Both Karaoke CD+G Creator uses global CD+G settings for the song (as defined in [CD+G Settings dialog box](https://docs.powerkaraoke.com/link/76#bkmrk-modyfying-cd%2Bg-setti)). **Color** and **Highlight** allows you to change the color of the text assigned to the selected mode, while **Alignment** controls the alignment of the text assigned to the selected mode. ![](https://docs.powerkaraoke.com/uploads/images/gallery/2024-08/embedded-image-t8oensvm.png) In Pro version you are also able to set lines count and vertical alignment for each of duet modes. The duet settings are global for the song. *Note: Colors and Text settings flags overwrite the duet settings.* --- ##### OVERPRINT IMAGE *![](https://docs.powerkaraoke.com/uploads/images/gallery/2024-08/embedded-image-ymbcyytr.png) Note: This event is available in Pro version only.* This event allows to display the image anywhere on the text. It may also be used to erase a part of the screen. [![image.png](https://docs.powerkaraoke.com/uploads/images/gallery/2024-12/scaled-1680-/3QOimage.png)](https://docs.powerkaraoke.com/uploads/images/gallery/2024-12/3QOimage.png) As you can see the settings are very similar to [**Display image**](#Display_Image_event) event. *File* You need to select the file containing the image. The following formats are supported: - BMP (Windows bitmaps) - JPG - PNG To invoke the file selection dialog box select **Browse** button. *Note: CD+G image format is 288x192.* Images may be of any size and color depth, however if they contain more than 16 colors or are larger than 288 x 192, they will be automatically converted to CD+G format. If you would like to use an image editing software to decrease the color depth and resize the images, make sure you save them as 4-bit BMP file. ##### *Link to file *and* Insert contents *options By default Karaoke CD+G Creator leaves the images on the hard disk and reads them when needed (**Link to file** option selected). This behaviour reduces the size of PK2 files and allows making changes to the images using image editors (you do not have to visit event again -- just edit the image and re-create CDG file). However if you delete the image file from disk, it will not be available. If you would like to share your PK2 files select **Insert contents** option. It will cause Karaoke CD+G Creator to include the image in PK2 file, so you may send it over to a friend or delete image files. Note that if image source file is deleted you will not be able to edit it any more. ##### *Display mode* These settings control the way image is painted. By default images are painted from left to right. You may change it by selecting any of the display effects. Checking the **Reverse** checkbox will cause the effect to run backwards, for example *Left to Right* mode will become to *Right to Left*. ##### *Position* You may select the position of the picture by selecting the appropriate rectangle. You may also display the image in any part of the screen. To do this select **Custom** and enter coordinates of left top corner of the image position. ##### *Force scaling* This option will force the image to be scaled to the size defined in **Width** and **Height** boxes. This size cannot be larger than the full screen (288 x 192). ##### *Display during* You may choose whether the image should be displayed after the preceding word is painted, or highlighted. ##### *Erase image* This option will erase the image instead of painting it (used if you have displayed an image in the same place before). ##### *Dithering* If the number of colors in the image is larger than 16, Karaoke CD+G Creator will reduce it. You may select the algorithm that is used to make the image look as good as possible with the lower number of colors. Selecting **none** will disable any dithering. The simples way to see how each of the algorithms works is to select it and then to click the **Preview** button. ##### *Resizing* This setting controls the way image is scaled if its size is not 288 x 192 (full screen). **Fit** will cause the image to be scaled up or down to take as much screen as possible. **Fit if larger** (default setting) will scale the image only if it is too large, it will not stretch it. **Crop** will not scale the image and will display as much of it as possible. All resizing modes retain aspect ratio of the image. ##### *Colors* Use this setting to define the number of colors that will be added to the current palette to match the colors in the image. Below are some suggestions how to set this option regarding the types of the usage:
Maximum Use this setting if you are displaying the image on the clear screen. You may also use it if this is the only image displayed on the current page and you do not change the colors for text
10, 8 Use this setting for the color-rich images for the songs with changing text colors (or duets)
4 This is the best setting for small images (stars, tick marks) displayed on screen. Remember that if you want to display the same image more than one you should select this setting for the first image only
Use current palette Use this setting if you are displaying the image for the second time or if you have already used up many of the palette entries (the total number of available colors is 16)
##### *Preview* Click this button to see how the picture will look. --- ##### SET TEXT AREA EVENT {{@228}} --- ##### TEXT SETTINGS EVENT Text Settings event allows to modify the properties of the text. [![image.png](https://docs.powerkaraoke.com/uploads/images/gallery/2024-12/scaled-1680-/p9Uimage.png)](https://docs.powerkaraoke.com/uploads/images/gallery/2024-12/p9Uimage.png) {{@227}} ##### *Text Effects* Select the text effect you want to apply. You have the choice of Outline (you may choose the size of the outline), Shadow and Heavy shadow. The color of the text effects can be set in Colors dialog box. You may enable any of the following text effects:
· None Text effects are disabled
· Outline Text is outlined by a single pixel
· Shadow A one pixel shadow is added to text
· Heavy shadow A two pixel shadow is added to text
· Outline (2-5 pixels) An outline of a selected width is added to the text
The color of the effect is controled separately from the color of the text. By default efects are painted in black. *Note: Enabling text effects decrease the speed of display the text. For the fast-paced songs it is recommended to disable the text effects.* ##### *Sweep words* Uncheck this option if you want to highlight the entire word at once, instead of coloring it gradually as it is sung. # Images Karaoke CD+G Creator allows to display images anywhere in the song. It also has shortcuts for adding title and credits screen. The following formats are supported by Karaoke CD+G Creator: - BMP (Windows bitmaps) - JPG - PNG To invoke the file selection dialog box select **Browse** button. *Note: CD+G image format is 288x192.* Images may be of any size and color depth, however if they contain more than 16 colors or are larger than 288 x 192, they will be automatically converted to CD+G format.
