Thread: Scrolling text speed and frame rates

Hybrid View

    Thanks. Initially I was trying to use attribute 22 without a desk. Although the Catalyst presets contain the value, it doesn't do anything. Now that I've got a desk hooked up, it works, but not as you would expect. With the value preset in the load/mark cue and tracking right through the move, the movement speed starts quite quickly and then slows down to virtually nothing. So the speed is changing, not constant. This is with a zero count cue in the desk. Strange. I checked the manual and it says that attribute 22 is a Damping Factor.

    Anyway, as it works that way, it is pretty much useless for what I want to do. Maybe Richard can change it?

    Thanks for your help,

    This is just to update for other users who might have this problem down the road. I had a chat with Richard and for this case, the best way is to use AE because pixel accurate positioning is needed. My problem lie in the refresh rate of the Fusion Mapper. In the Catalyst frame rate settings, I was using 25fps. Turns out I needed to use Screen 2 div 3, which for my display is 25.01Hz. Turns out that that 0.1 Hz was causing my inconsistent glitching. It started doing it again when I turned off full screen mode on Screen 1, so if anyone else runs into this problem, keep both screens in full screen mode.

    Cheers,

    Just a followup and not related to your results needed. But something for people to be aware of with Image Speed:

    This sounds like a fade time on the channel. I know you said you Marked it but it sounds like there is a fade from zero Image Speed to some value in Image Speed.
