You are correct about it being very much slower than the 8bit version, of course  |
So 16bpp output is storing 10-bit data in 16-bit variables? I'm guessing there isn't any redundancy/that x264 also does something similar?
Leading on from that, obviously it's much slower, but is it more space-efficient than 8bpp? Or rather, is there any reason to test/compare 16bpp/10-bit to 8bpp at this stage?
I plan on comparing some anime credits, so I want to make sure I am making fair comparisons to default/fan-tuned encodes(8-bit vs 8-bit, or 10-bit vs 10-bit, or all vs all). Just looking through different ones at the moment to find problem-cases(difficult to compress but not because of noise)
