Might be the case.

I think you miss understood the 'scenecut' here. When in a NLE clips are
organised and placed on a timeline, it is pretty known at what time which
clip is played. To x264 this information is only available from an image -
not on meta data level, which I would like to use to hint the encoder.

Offtopic; although a good initiative, this will nadly not update any
hardware solution. Never the less... getting a better MPEG-2 encoder may
be a good thing given the huge installbase.
