This is a service release to fix recording on macOS 10.12 and 10.13, which had been broken in VVV 5.3.3 due to the recent changes made to support macOS 10.15 Catalina.
If you are running VoceVista Video 5.3.3 on macOS 10.14 or 10.15, or on Windows, you don’t need to do anything.
If you still run macOS 10.12 or 10.13, please upgrade to this version VVV 5.3.4.
Also, on some specific Macbook Air models, the recording produces a distorted sound. If you experience this issue, please check out this page for a beta version and a fix.
