Menus

Hi
It is impossible to get cursors on vcd or svcd, but ive seen some vcds with effects when selected something from the menu. for eg i play my vcd and select (1) -Play Movie, then number 1 is changed into someother colour. how does that work.

Hi!
It's correct that you can not have overlayed grapics on a VCD/SVCD menu like those on a DVD. However there's a way to make something in beetween these two.

Instead of assigning button 1 to the mpeg-move file, you can assign it to a new mpg-still picture. Let's say you have a main menu with 4 choices on (1 to 4). For each number you make new pictures, only with different colors on each numer. Number 1 is yellow and the rest is white. Number 2 is yellow, the rest white and so on.

When you press button 1, then the new picture will display, showing a similar menu, except that the selection is in a different colour. The picture is usually set to be displayed for about 1 - 2 seconds, and then the mpg-move is started. By doing this it will look like the selection is lighten up, but instead only a new menu-picture is shown.

It's a little bit more work, but that way you can make good looking VCD/SVCD menus.

Hope that explains it to you.

Hi znooky
Lets say we have the 2 different colour mpeg stil for each selection but how would i adjust that in vcdeasy - interactivity.

Hi!
First add the menu-picture, then add the corresponding menuchoice pictures and last add the mpg-movie files.

I've made a small example, with a menu containing 3 different choices. Take a look in the XML-file below:
