There's certainly some trade-offs that could be possible by limiting the flags and quality ranges for the output similar to what we already for h.264 and h.265

There's certainly some trade-offs that could be possible by limiting the flags and quality ranges for the output similar to what we already for h.264 and h.265 hardware encoding. Another rando possibility is FPGA cores or someone figured out how to do the calculations with GPU or TPU acceleration.
