Comment (by edumj):

 There's still something wrong with overlaying and colors.

 If I try to overlay subs, I get "[matroska,webm @ 0318c660] Read error"

 ffmpeg:
 {{{
 ffmpeg -palette
 "ffffff,ffffff,ffffff,ffffff,ffffff,ffffff,ffffff,ffffff,ffffff,ffffff,ffffff,ffffff,ffffff,ffffff,ffffff,ffffff"
 -i "%~1" -filter_complex "[0:v][0:s:0]overlay[out]" -map "[out]" -map
 0:a:1 -f avi -c:v libxvid -b:v 1500k -vtag XVID -c:a libmp3lame -b:a 128k
 "%~n1 overlay.avi"
 }}}

 output:

 And if I convert it to XSUB, now they show, but transparecy of colors
 seems inverted, text is transparent and background is opaque (with any
 palette color combination).
 It says "Color index 0 is not transparent. Transparency will be messed
 up."

 ffmpeg:
