yw? I didn't do much for you, hardly the best. Only reason I don't just call mkvextract directly is I couldn't be arsed to learn its syntax.

Huh? What is this thing in? It's an APU with unified memory, it doesn't have any actual VRAM of its own, the CPU and GPU share. I don't even know if "dedicated" GPU memory is actually exclusively allocated to it or if it still shows up on the "Memory" tab. With older integrated graphics (way older) without UMA, if you set your IGP to e.g. 1GB in the BIOS, it DID make 1GB of RAM vanish from what you saw under "System".
"Shared" is it normally (with a dGPU) just using more of the rest of your RAM as if it were a pagefile. Or at least it's supposed to be. No idea if there's any distinction in how quickly it'd access one or the other since they're both referring to what is physically the same big ass pool of memory.
Picrel is my dog of an RX 5700. It's got 8 GB of RAM. The "shared GPU memory" is bullshit, drawing from my 32 GB of system memory. I still see the full 32 GB under "Memory" in Windows. Games will never try to use more than the actual 8 GB of VRAM. If I try to access >8 GB with e.g. DirectML, my computer will BSOD.
You check the BIOS?

You are not going to be able to allocate 96 dedicated and 0 shared.
