RE: How to add a 3D avatar to your website or blog

Is there some minimum time for a video. I uploaded a four second video of my avatar talking, but it does not appear to play. The first frame of the video appear, but nothing more. 

I'm running this from the Avatar screen. Here's the code:

<script type='text/javascript' src="https://www.botlibre.com/scripts/sdk.js"></script>
<script type='text/javascript'>
SDK.applicationId = "xxx";
var sdk = new SDKConnection();
var web = new WebAvatar();
web.version = 8.5;
web.connection = sdk;
web.avatar = "37788053";
web.voice = "cmu-slt";
web.voiceMod = "default";
web.width = "300";
web.height = "300";
web.createBox();
web.addMessage("Hello, my name is Tuesday", "", "", "");
web.processMessages();
</script>
