It may be worth noting that while the M1 and M2 have the same instruction set, there is no guarantee the video processing blocks are identical. At a minimum we know that the ProRes acceleration supports 8K resolutions in the M2. I got burned by a subtle change in behavior for videotoolbox between Intel and M1, so it's possible there are comparable differences between M1 and M2. If the tests include validating hardware acceleration then there may still be benefits in running the tests on both platforms.
