To help speed my program up, I need to do a video video memory copy of vertex buffers, but the buffer im copying to has less elements than the buffer im copying from... is there a way to cap off the copy early?? (dx11)

ID3D11DeviceContext::CopySubresourceRegion should be able to do what you want

Yes I thought so, but its designed for textures... could someone take the time to give me a really mega short 4 line example of how they think I should do it, remember its just a couple of vertex buffers.

From what I can tell it also supports 1D-resources, which a vertexbuffer could be classified as I assume?(Or perhaps that's only 1D textures)

yeh no worries fellas, i got it working, you actually say the amount of bytes you need to copy on the x axis, not number of elements. (elements*size)
