Here's a overview of the different components of our recording system:
-
Presenter's laptop should use HDMI output.
You should use an adapter if the laptop doesn't support HDMI output:
Here's a Mini-Displayport to HDMI adapter.
More adapters. -
HDMI signal is sent to a HDMI splitter, that sends 1 signal to the projector. Another is sent to the screen grabber.
-
The HDMI signal is sent to the Avermedia Live Gamer Portable.
-
The Avermedia Live Gamer Portable can record the video into an SD card in PC-Free mode. But from past experience, its more stable to use a PC to record that feed.
We use a webcam to record the speaker. Its the easiest to hook up directly to a laptop. Downside is that it doesn't have optical zoom, so you will need to move the camera closer if you want to get a closer shot of the speaker.
The webcam is mounted on a tripod.
For voice recording, we use a condenser microphone for maximum sensitivity.
Here's a condenser microphone on a small microphone stand. Its connected via a 3-pin audio cable (also called an XLR cable).
And we connect the condenser microphone to a XLR to USB sound card (Blue Icicle).
The Blue Icicle has a USB interface.
All the 3 input sources are connected to a laptop via USB. We use a software video mixer to integrate all these 3 sources. The output from the software video mixer is one single video file that is pre-edited. This video file is then uploaded to YouTube.
The software video mixer we use is called OBS Studio. This software is free and open source. And it runs on Windows, Mac and Linux.
Here's a short video of us setting up our recording equipment.
