While the built-in wireless share feature in Zoom supports AirPlay Mirroring, which allows you to share your documents and photos from TrialPad in Zoom, this Zoom feature does not support AirPlay Video, which is what you need to play video from TrialPad in Zoom.
Here are a couple options to play video during your TrialPad presentation in Zoom:
(1) Use Reflector, a third-party software created by a software company called Air Squirrels. Reflector uses similar technology to Zoom’s built-in share window, but unlike Zoom, it supports both AirPlay Mirroring and AirPlay Video.
Install Reflector on your computer (not on the iPad), and use Reflector to wirelessly connect your iPad and TrialPad. When you are ready to present in Zoom, choose to share the Reflector screen. Here is the link to download Reflector software: https://www.airsquirrels.com/reflector
(2) Use an HDMI to USB converter such as the USB Capture HDMI by Magewell, Part Number 32060, at www.magewell.com
This is a bit more complex of a solution that tricks Zoom into seeing your iPad as a camera. Connect the USB converter to your computer, and connect an HDMI cable between the converter and your iPad using the Apple USC-C Digital AV Multiport Adapter or the Lightning Digital AV Adapter(depending on your iPad model).
When you are ready to present in Zoom, click the Share Screen button, click on the Advanced tab, then click on Content from 2nd Camera. Make sure to also select the Share sound and Optimize for video clip options at the bottom of the window.
NOTE: For the best presentation of video you will want Optimize for video clip turned ON, but for the best presentation of documents, you will want Optimize for video clip turned OFF. Tap the More button (three dots) on the floating control panel in Zoom to select and deselect Optimize for video clip as needed during your presentation.
Both of the above technologies will also work if you want to use TrialPad in a remote meeting other than Zoom, such as Microsoft Teams, Webex, etc. We are unable to provide any more support for these options beyond this information.
