i'm not in sintel team, so i can't answer this question. 

I send an email Ton Roosendaal (ton blender.org), will see if we will
get some response.

I still think it will be good (especially for advocacy) to make
libtheora writhe some encoding options to the header. Currently it write
only encoder version. Relevant info is bitrate/quality and passes. So it
will look like:
k2000p2 (2000 kbit, 2 pass) or q60p2 (quality 60, 2 pass)

every thing together will be:
Xiph.Org libtheora 1.2.0alpha 20100924 (Ptalarbvorm) q60p2
                                                     ^^^^^
