The encoder will calculate scenecut costs based on the best compression
efficiency (i.e which modes use the fewest bits). This trumps any metadata
from the NLE. If you still think you can do a better job than the encoder 
you can force frametypes or change the scenecut thresholds.

This is not the case. There are many well known names who will be moving
to x262 when it is done for TV/DVD and some who are already in the process
of moving to x264 for TV/Blu-ray.
