Why Does It Seem That My Words Are Not in Sync with My Lips?
When only 2 participants are connected (see left picture below), you see yourself in the local cam view without any delay and the video/audio is directly connected between both participants via the Eyeson cloud service (SFU mode).
With Eyeson video meetings with more than 2 participants, all participants are shown in the same video and audio stream. The audio and video streams are sent to our server and mixed into one single stream ("Eyeson One View") before being distributed to all participants (MCU mode).
When you look at your own video on your desktop, mobile phone, or tablet, you see yourself in the video that has already been sent to the server and received back from there. While you are listening to your own voice in the moment you are talking, this can give you the feeling that your voice is not in sync with the video.
Don't worry though - your voice is EXACTLY in sync with your video for all participants in the meeting. What we do for you is filter out your voice for your client.
This means that when you hear yourself talking, you are receiving the video actually a bit delayed (less than half a second). However, the audio has not been received with a delay at all from the server.
This effect of the Eyeson MCU+ is specific to Eyeson Video Sessions. Other systems show only your local cam preview during group video calls, while Eyeson shows your real transmitted video, which has already passed the server.
We proudly serve you with our patented technology, which allows you to switch between MCU and SFU. Eyeson automatically switches between MCU mode and SFU mode depending on the number of participants connected. This is how we minimize the bandwidth even for bigger video conferences.
