java.lang.OutOfMemoryError

[cdag98]

I am trying to put large video files (~2gb) into a series of pictures (tried very large and small with no luck) and I am consistently getting this error, I did -XMS10G -XMX12G and -XSS10G at the same time and individually and none will work. The program goes up to about 4g ram usage then spits the error and stops. I'm not using this for avoiding my government or anything, just trying to find a cool way to share files, so it's not life or death but I would appreciate any help.
Is this file size absolutely too large? I was gonna mess around and encode music albums into their cover art and movies into their promo art bundles since they need multiple files. I have 32gb ram and a 3090 so if this is possible let me know please, this could get really interesting. :)

as an aside, could anyone tell me what the ratio of hidden data to mask data needs to be? (eg 1gb stored data requires 2gb mask data or whatever it is, also what resolution/file size images are ideal)

2GB files are really large and I doubt that even 12GB memory allocation would work here. The image will take far larger amount of memory when loaded by java, because original size on disk is typically just compressed size. And it would need further more memory to perform various operations.
