this is talk by TDs from ImageMetrics (who specialize on facial animation for games and film industry).
First series of videos (7 parts) is general experience with their facial setup (mostly next-gen game level quality, but could be applied to film digi doubles work I think). Rigger TD is answering questions.
Second video (first half) is about calibration of ImageMetrics software to any facial rig they get and showing how their plugin can analyze facial performance video, identify poses and drive the rig by interpolating the calibrated poses. Quite interesting.
Second half of this video is about facial topology, discussing neck area as well (starts from 00:36).
