I (re)read a lot about video optimization for our numerous systems in our installation.
unfortunately, we have received all the video footages very late and it lags on each one.
even with a video of 1Mb/s bitrate (a bit too low for us), I painfully output 14 frame per second (!!!!) for the video with only a qmetro + a jit.qmovie + a jit.pwindow
what did I miss ?
