Limit RAM usage to avoid crashes

Add this line into your script:

core.max_cache_size = 1000

The value is in MB so 1000 = 1000MB

Example

import vapoursynth as vs
import havsfunc as haf
import muvsfunc as muvs
import mvsfunc as mvs
import kagefunc as kage
import descale as descale
import G41Fun as fun
core = vs.get_core()

core.max_cache_size = 1000 # this means vs will use 1GB of RAM

...
