Fast H.264 Video Compression on the MacBook Pro Beats the 2013 Mac ProRegarding an earlier post about astonishing MacBook Pro video encoding speed, Iain A writes:
About QuickSync, regarding H.264 compression. Its entirely possible for a 13 MacBook Pro to outclass a Mac Pro in H.264 encoding, if done the right way.
- QuickTime Pro X will use QuickSync on supported Macs.
- FCP X will use QuickSync in Faster Encoding but not otherwise.
- Compressor will use QuickSync only in Single Pass H.264 encoding for .mov and .mp4 targets, so its necessary to make a preset which uses single pass and not multi-pass.
The QuickSync feature is only supported on consumer CPUs, and not on the Xeon in the Mac Pro. I performed a few tests with a colleague here, and the H.264 encodes are quite revealing:

Faster doesnt mean worse, either. While its possible that you could see a difference in quality with the faster encode on some sources, I simply havent seen it with the default (high) data rates that Apple uses, which are of course recompressed anyway by online video sharing services. QuickSync is a massive time saver, and its a real shame that the Mac Pro cant use it.
