Need help with gif file sizes

Been trying to make a version of mcsm in scratch I found a 2 ways but both are not very good. 1: don't use video but use singular images like in the one I released here or 2: use video and audio but it takes up so much file space and it can literally only be created on turbowarp, the gif files are too big. So does anyone have a solution to compress the gifs, but you can still see what's going on, or should I just give up and use option 1.

Need help with gif file sizes

Scratch doesn't support gifs; the frames are converted to separate costumes. Your two suggested methods end up as the same thing, just with different bit depth and frame rate, dependent on the source file(s).

Some ways to reduce the size of the video:
  • Use a lower bit depth (fewer colors)
  • Use images with smaller dimensions
  • Use a lower frame rate (fewer costumes)
  • Upload jpgs as they use lossy compression (make sure to verify they are saved as such and not quietly converted to png)
  • Where only parts of the video are changing, only have costumes that change that part. You can use pen stamps to show multiple layers of costumes at a time.

Thanks, I'll try this!
