Limit Cache (MB)

[Dan64]

Hello Selur,

  In Hybrid under Filtering->Vapoursynth->Script, there is the option Limit Cache (MB).

  I'd like to understand how this option is used, because by enabling/disabling it, I don't see any change on the generated script or the vspipe command used for encoding.

Thanks,
Dan

the tool tip seems clear to me,...

If you enable it and:
a. enter a value, that value, i.e. 2048, that value gets set as max_cache_size

# Limit frame cache to 2048MB
core.max_cache_size = 2048

if a value of 0 is set and '8GB for > SD' is selected and your output is > 720x576

# Limit frame cache to 8192MB
core.max_cache_size = 8192

will be used,...

I turned this option to 16GB, but I don't see in the generated code the lines

# Limit frame cache to  16384MB
core.max_cache_size =  16384

The cache settings is also depending from the clip input resolution ?

Yes, unless you enter 16384 as number, instead of 0, or use the 3/4 option, those limits only are activated on content that is greater than SD, HD or UHD.
