I have setup a character to use on my stream. everything works great expect the realtime lipsync will stop after a while, the rest of the realtime tracking works without an issue.

Is there a timelimit on how long the realtime lipsync will run and if so, how can I extent it. If there isn't an time limit, what could be causing the issues?

Thanks everyone for your help on this.

Edit: after watching my test, i get the feeling the timelimit is 15 mins, is this correct and can it be extended?

Wondering if anyone can help me with this. Currently I am having to stop and restart it every 15 mins and it is very frustrating and also leads to the application freezing sometimes.

In your case, I suggest you separate the project as several videos and combine those videos in the external post video editor. 
I am curious, why are you recording lip-sync so long? which purpose would you like to do?

That won't work, maybe I didn't explain the problem correctly. I use this as a live avatar while I am streaming (think live on twitch). It works great and looks amazing but the lip sync stops after 15 mins. I understand that I think projects are 15 mins long and so that works well in that time frame but while I am in the preview mode and it is not saving the data, can the realtime lipsync go longer. All other live tracking continues to work.
