Slow button interactivity

Hi,

I'm using an HD410 3.1.36

Basically there are 12 jpeg images which are a list of 12 names , 11 in white and one in red. For jpeg 1 the first name is in red and 2 to 12 are in white, for jpeg 2 the 2nd name is on red, names 1 and 3 to 12 are in white and so on. Two buttons are used to scroll up and down the list, a third button selects the clip. The jpegs are all 1024x768 which matches the videomode.

In the down direction e.g. going from jpeg 3 to 4 it is fast but in the up direction e.g. 4 to 3 it is very slow, about 1 second or more which makes for very sluggish interactivity.

Anyone know how I can get it to respond quickly in both directions?

Thanks,
Neill

    I've removed most of the interactivity so now all there is is the 12 jpegs which you scroll through on a button press.



    When the csv file is organized so that you scroll from top to bottom, the images change almost instantly.  When the file is organized to go from bottom to top (as below) it takes more than a second to respond.  



    This is doing my head in!



    Anyone got any ideas? I think I have tried everything.

    When your images are listed one after the other, the next image in the list is cached in memory. That's why going one way is faster.



    The only other way to improved time to open is to avoid any scaling. So, the images must match the resolution you are outputting. so, if you are using 1024x768, the images should be 1024x768.
