this code generates error and I know why  
Is there a way to get over it  
I need to animate each 100 steps because the file size reach 1GB with each step animation  
How to generate animation with small file size given that there are 6 thousands frames in total

```julia
anime = @animate for ist in 1:Nsteps
        if (ist%100 == 0)
            scatter([Person[i]["x"] for i in 1:Npopulations], [Person[i]["y"] for i in 1:Npopulations],legend=false, color = [Person[i]["color"] for i in 1:Npopulations])
        end
end
    gif(anime, "E:\\0.9prob.gif", fps = 50)

```

I guess you cannot use a .gif file with 6000 frames… This is not what the .gif format was ment for.

You can save the images as .png and create a video with high compression out of it using ffmpeg.

Example:

```bash
ffmpeg -r:v 20 -i "video%06d.png" -codec:v libx264 -preset veryslow -pix_fmt yuv420p -crf 10 -an "video.mp4

```

This example assumes that the .png file names look like this:  
video000000.png video000001.png etc

So you first need to save them in this format.

This package might help: [GitHub - JuliaIO/FFMPEG.jl: Julia Package for the FFMPEG builder binaries](https://github.com/JuliaIO/FFMPEG.jl)

Does this answer your question?

You can also try `mp4(anime, "video.mp4", fps = 50)` ([code example](https://sosiristseng.github.io/juliabook-visualization/plotsjl-gallery.html#animations) taken from Pllots.jl)
