Ok, I've bought several different software packages for recording video with my built-in isight but no matter what I use my mouth seems out of sync with the audio and the framerate seems rather low. I've tried using ishowu HD, evocam, and built in photobooth. No matter what I do the framerate seems low and I struggle to get good quality. I would like to be able to record in good quality under ishowuHD so I can record from the isight and my desktop simultaneously. What can I do in terms of settings to get the most out of my imac's built in isight? Is there a certain video size that agrees with it and/or a certain compression format? Also, is it normal to wave a hand in front of the cam at a fair distance, not too fast, and it to appear blurred? Thanks ! I need help !
