As it says in title. I couldn't find a way to convert it with a file conversion system already on my computer using a Google search, and nor could I find any online converters without a size limit.

Eventually I did find a website which recommended uploading it to Keynote as a one-slide presentation and saving it as a .gif, but I suppose my computer, as it's quite old, couldn't handle downloading it and crashed.

What would be a good way to convert it with minimal stress on my system? Download time isn't a problem as long as it gets done.

  • A 1.5 Gb mp4 video is going to be hours long. Why do you need this as an animated GIF?

For a file this large you won't find a free online converter. As it would take up to much computational power and the resulting .gif file will be a multiple of the 1.5GB input file.

Best thing you could do is download ffmpeg and convert it on your local machine. Depending on your input file and quality requirements, you may need to experiment a bit with the various options. How do I convert a video to GIF using ffmpeg, with reasonable quality? is a good starting point for this.

In general it would be interesting to know why you need such a large video file as a .gif file. Because the .gif format probably isn't very well suited for the application in mind.
