Instructor technical setup, online
This is online-specific instructor tech setup. For general, see Instructor technical setup which also applies here.
The information in this is currently specific to Zoom teaching and livestream teaching.
See the list in Instructor technical setup, which includes points for online.
Audio quality, and balance between instructors, is absolutely critical to good online work, especially teaching. Consider the following:
Can you adjust your microphone volume from very low to higher-than-needed? Make sure your dynamic range is larger than “barely working”, so that you have some room to adjust for later.
Do you have a high-quality headset? A headset with microphone is the most reliable, but if you can get a desktop setup working well, that can be good too. Always have a high-quality headset for backup anyway.
If you have a bluetooth headset, consider:
Bluetooth headsets have significant latency compared to wired or purpose-built wireless protocols like gaming headsets have.
The microphone might not have enough bandwidth (if it’s part of the same headset).
Bluetooth 5 is much better in both latency and quality.
Consider investing (or getting your work to invest in) some high-quality headset or desktop audio gear.
“Ducking” is when the first words are silenced/quieted by noise cancellation, until it detects speaking. To avoid this, don’t use “high” noise cancellation (as low as possible is better). If you need high cancellation because of background noise, switch to your headset.
You have to assume the smallest screen from learners and plan for that. You should share a portrait screen: either a portion of your screen, or one window in portrait mode. See the examples below.
Learners have a small screen, and need room for their own terminals and web browser open, too. A big screen or multiple monitors is the special case.
Sharing a 1920x1080 screen is not a good idea: you need to make all the text size large so that learners can scale it down to have room to do their work. Pixels are wasted. Instead, force yourself to save space by using a normal font size but sharing less of your screen.
Zoom now has a “share portion of screen” (Screen sharing → Advanced → Share a portion of the screen).
For livestreaming, our aspect ration is 840×1080 (portrait). This is a bit less than half your screen. This is 43% of the width of your screen and the full height, for a standard FullHD screen.
When streaming/recording: Never stop sharing a screen, ask someone else to take it over. There is a chance that the view goes to “gallery view” in the recording or stream, which makes video editing harder or disrupts learner privacy.
