There are several gain stages in most audio paths: the wireless mic output, gain on your mixer, channel volume on your mixer and then master volume on your mixer. Once the signal hits the ATEM you have another volume there as well. You can bring up the level until the loudest sounds hit yellow on the led meter on CamSlicer. The trick is to increase without hitting distortion. Keep in mind that national ads are […]

Wirecast Rendezvous & WebRTC
Zoom uses a technology called WebRTC – Web “Real Time Communications”. Very simply put, when two people are having a conversation on Zoom – the browsers are talking DIRECTLY to each other: no encode, decode, player or anything. This also limits the number of people that can be on the call (I think 100 is about tops). You can take and WEBCAST a zoom session, and the people talking in the zoom session will be […]
High CPU Load on Wirecast – Maintaining Audio Sync
One of the biggest challenges in live webcasting is maintaining good audio sync. The best way to do that is keep CPU load down. We have seen incidences of CPU use spiking to 80-90% in the past week (You can run activity monitor on your Mac which will show CPU usage) – and the result is always the same: stuttery fade transitions & de-sync of audio. Luckily a little research has shown how to avoid […]
System Check for Live Webcasting
Here’s a methodology that we’ve used in the past that’s very effective: 1) Create a looping, motion graphic or sequence (logo with music, some special effects). Keep it generic. 2) Create a layer on wirecast and add this video. Use the tools in wirecast to set it to loop. 3) Use this to test audio & video feed to camslicer. 4) Go live on this looping motion graphic. 5) Instead of having Zoom on another […]
