GifImage Heap Space Error

I have been working on playing a video in Greenfoot by playing a gif and mp3 file, and have been using information from this thread to display my gif. Older Topic The problem is that I run into a java heap space error when I try to play the gif. "java.lang.OutOfMemoryError: Java heap space" I'm fairly new to java and coding and I am trying to see if I can fix this. By going into the GifImage class and decreasing numFrames to 30, I don't get an error and can play the first 30 frames of my gif. Any thoughts?

Error is basically just telling you that the environment went out of memory because you're saving too much stuff. Try a shorter gif or decrease the world's size (effectively cutting the image size as well), maybe u're running an infinite loop too but i doubt that when it works with 30frames/s

You can also increase the java heap space. In any way, you could show the code so we can see if there are any mistakes.

Here is some of my code in my Video class: 
    public Video(int n)
    {
        gifName = "videos/Gif_" + n + ".gif";
        gifImage = new GifImage(gifName);
        adNumber = n;
        adSound = new GreenfootSound("Ad_" + n + ".wav");
    }
And in act(): 
setImage(gifImage.getCurrentImage());
The gif is 15 seconds long, as I am trying to simulate a video. I might just try cutting out every 10 frames and playing the gif at 1/10 of the speed. Thanks for your quick responses!
