Looking at mencoders ve_xvid4.c I had to realize mencoder has a very limited zone support.
One can specify a startframe, a mode (constant quant | bitrate modifier) and a value for the mode, no way to enforce a keyframe at the start of a zone, enable greyscale/chroma optimizer/cartoon mode or modifying BVOP sensivity for the zone. :( (it is possible to enabled greyscale/chroma optimizer/cartoon mode for the whole clip)
Since I want to at least set be able to let zones start with a keyframe (for chapter starting points) I ask myself what alternative option besides mencoder is available on linux? (and does this alternative allow to set keyframes at zone starting frames?)
