WOW! Exceptional improvement in a single stroke! Thanks! :) Why is it that ffmpeg degrades the quality with default settings? What does it assume that the setting is? (sorry for the newbie Qs, but this area is until now outside my cognitive map! ;-) Thank you both for your suggestions. The recordmydesktop looks good, but I am not sure if I will have to transcode it to make sure that it would also work for MSWindows users? Is ogg MSWindows 'compatible'? Now, I hope I'm not getting greedy, but how do I add voice recording to the above stanza? Or do I have to record voice and then package it along with the video in a container as a separate step? Once I achieve that how can I go back and edit the voice part? -- Regards, Mick
