I am still confused when it comes to manipulating h264..
Are there ways to utilize the "load h.264.ini" found in the ML nightlies? Or are you rather talking about a different set of options found in the TL?
Anyone had any positive results tweaking the 5Dmkiii h.264 ? Can't really figure out if this approach was abandoned due to the awesomeness of RAWvideo or simply because it didn't improve much.
