So the past few times I have been video chatting using imessage my buddy has complained that i was blurry. I told them to launch the connection doctor and they said that the audio was 95% and video was at 65%. I launched it as well and it said both audio and video were 100% and I could hear and see my buddy just fine, but I was blurry to them. I usually have pretty good internet connection. Any thoughts on how to fix this?

    Hi,

     

    The Connection Doctor "rates" shown a the green bars normally are a representation of the incoming feed.

    Therefore they are "good" to you and you are "not so good" to them.

     

    At the very lowest level of internet speed a Video chat 1-1 can be done on as little as 128kbps both up and down.

     

    Obviously since iChat started there have been vast increases in Internet Speeds for many people.

     

    The biggest issue comes when one end is faster then the other.

    The slower end can get pushed so  much data it cannot cope.  At the same time the Speed may in fact vary as well and this can add further problems as then the iChat Buffering can come in to effect which tries to sync Audio with Video but will drop Video frames to keep pace or smooth out jumps in speed.

    There does come a point when it will drop the Audio as it cannot sync it properly.

     

    As a first step both ends should go to the App Menu > Preferences > Video section and set the Bandwidth Limit to 500kbps.

    This will cap the speed if one end is mega fast compared to the other.

    It will also drop most connections below the speed where any variances will take effect.  (a 5% variance on a 10Mg service can be 1500kbps - which is faster then most video streaming site.  If the slower end is not even reaching that speed iChat or Messages can spend the whole chat trying to sort out the speed.)

     

    After that the things that slows up you sending data is things like poor lighting and the like such as adding a "busy" background via the Video effects.
