Hi,
bitmap (.bmp) isn’t optimal for storing bitmap animation. better to use .gif/.png/.jpeg
from https://docs.microsoft.com/en-US/windows/win32/memory/memory-limits-for-windows-releases :
- x32 app can handle 2 GB by default
- x64 app can handle 8 TB by default
so using x64 would solve your issue.
actual status depends on RAM installed on that pc.
