Hi Guys, my configuration is this:
- Macbook Pro (early 2015)
- MacOs Catalina 10.15.3
- Webcam Logitech C920
- Neewer NW35 Mic into Focusrite Sapphire 6 USB
I have an audio profile with some effects on reaper and I managed to get this audio that come directly from reaper (with all effects ecc..) into obs as a source via IShowU, so I can have a better mic audio quality then using OBS audio settings.
The problem is that, when I stream everything is ok at first, audio and video are perfect as the sync, but as far as the stream goes on, the cam starts to "lag" and I found myself out of lipsync, the game that i'm streaming works perfectly for all the time, as the audio, but webcam goes wild and desync.
I'm streaming at 720p 30fps, OBS is set in that way and also the webcam, I have anti flickering at 50 PAL (i'm in Europe) and I will attach the screenshots of my settings.
P.S I have fiber internet connection that's very fast with 17 to 20mbs in upload
Can anyone help me with this? Thks in advance

Matteo
