Hi,

We have a question about VMIX CALL.

When we start a call, the person join us by clicking on the link we share. The call starts correctly and it's sync, lipping OK.
But after about one minute, the lipping is running unsynchronized with up to 20 seconds between image and sound.
We tried everything in the vmix config. Some tests are going well but others with new callers are so unefficit. Lipping goes wrong after few seconds anyway.
We use NDI to send the call to an other computer.

PC CONFIG :
- Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz - 3.40 GHz
- RAM : 32,0 Go
- NVIDIA GeFORCE GTX 1080

Does the callers need to have a specific config on theyr computer, watch about theyr connection, or something like that ? Has Iphone or smartphone different cam config to create sync troubles or...?
Thanks for your answers.

TD.
