iChat freezing and not responding during video chats!

Hi

First have you set the Quicktime streaming setting, goto sys prefs/quicktime/streaming/streaming speed, set to 1.5mbps

In ichats prefs click on video and change bandwidth limit to 500.

Restart iChat.

My quicktime won't open either

This worked great! You've just made my night 🙂 Thanks!

I'm having trouble finding the Quicktime menu. Where exactly is that?

i tried changing my settings to the settings mentioned earlier and my ichat still freezes. any ideas? i use ichat a lot to talk to family...i would for it to work again.

I see you post this same solution to many people. I have tried it to no avail. I am having the exact same problem with the video going out about 30 seconds after the chat starts, then the app freezes if I try to do anything. I spent 30 minutes on the phone with Apple Care troubleshooting it today.

I'm starting to think my ISP is the root of the problem (Cox). http://www.canyouseeme.org - also says that it cannot see my computer on port 16402 (which is what I understand iChat tries to use in Leopard).

Even if setting a bandwidth limit of 500Kbps worked for me I would still be unsatisfied, as I don't understand why I should have to limit the quality of my chat when I have a connection capable of 15Mbps down /1.5Mbps up.

This has been going on since last year with Comcast and seems to be spreading to other cable companies, see if this thread explains it for you.

Okay, when I called Apple yesterday, they had me try video chatting with a demo iChat user that they have set up for troubleshooting. The video is just an iPhone commercial on loop, but when I am 'chatting' with it, the video never messes up (at least not in the first 5 minutes or so). We both get a frame rate of 15-20 and a bitrate of about 1850kbps (I'm set to none for bandwidth limit).

There are a couple of different ones available, I think. Try entering either address below (the 2nd one is just a regular AIM account) and see if it will work for you.

This can't be a bandwidth or port issue, as it occurs even when video chatting with people within the local network.

It must be down to the QuickTime 7.5.5 update that came with iTunes 8 last week, as machines that do not have this update installed do not experience this problem. Hopefully Apple will release either a QuickTime or iChat patch to address this issue. The 10.5.5 update does not fix the problem.

Same exact problem here, Dutifully performed the update then IChat freezes every time we use it. Used to work perfectly. Now video freezes in a couple of minutes, audio craps out a few minutes later. Now cannot IChat with our son in college. Hurry up and fix this Apple!

I, too, am having the same problem since the 10.5.5 update. My girlfriend is a few states away, and we switched to using Skype. It's not as good quality.. but at least it works! www.skype.com

Setting quicktime to 1.5 mbps works as long as you change the bandwidth in ichat pref settings.. also, if 500 does not work try 200 or 100. I set mine to 100 before it worked.
