nice!

im using

alias screencap='mytemp=$(mktemp); \
 ffmpeg -hwaccel auto -r ntsc -f pulse -i default \
 -f x11grab $(slop -D -n -f "-video_size %wx%h -i :0.0+%x,%y") \
 -x264opts opencl   -y $mytemp.mp4 ; \
 echo $mytemp.mp4'

slop is an external program, double clicking in slop will report a window frame.

i don't get audio sync, having added the audio just a minute ago. still some features to examine here.
