  • Slider Control for Speed of Text Animator

    Posted by Helen Frost on November 19, 2025 at 11:08 am

    Hi, I’m trying to create a MGRT where the speed of the type animation can be adjusted with a slider depending on the number of lines in the piece of text. I’d be using this alongside an anchor point expression (to lock the text to the centre of the screen regardless of the no. of lines).

    For context, each line will be fading on with an Opacity Animator, and there will be up to 10 lines of text.

    Is anyone able to help with this please?

    Hi Helen! So basically you’d like to control the speed of the start or end range for the animator?

    You could add a slider and use this expression on the start property:

    var s = effect(“Slider Control”)(1).value;

    linear(time, 0, s, 0, 100)

    It uses the slider to determine at which second the animation is complete.

    I also did a script for these kinds of situation. You can try it in a free trial and use it how you want. It might help you if you do MOGRTs. Here it is:

    Let me know if you got questions! Cheers!

    Hi Yoan,

    Thanks for this! I managed to find another method in the end, but this script will be really useful for next time!


    Thanks,

    Helen
