FFVideoSource("alt.avi")
AssumeFPS(30.0)
ConvertToYV12(matrix="Rec709")

Source was FRAPS I420.
With 2.16 the x264 result looked like this:

2.17 (too dark):

2.17 looks more correct to me, and I know Fraps has some super mysterious color matrix magic going on, but I can take a look anyway. Post a sample.

Your Avisynth script doesn't convert to RGB either, so that conversion happens elsewhere. What colorspace is FFMS2 outputting?
