Constant video interaction is great to look as if you are working but isn’t the best use of your time. Rather than being on the video call for everything, it’s better to make a video recording of the particular action (in your own time) and let others see it when they can.

Use asynchronous video to be able to show your face and expressions when needed, getting in touch the real way in a remote setting. This leaves time for your 'deep work' activities.

They are a great way to call someone and talk to them without disturbing them in real-time. 

A phone call is no longer polite now and sending a voice message while discussing an idea, feedback, or reflection is a ‘soft’ method that works asynchronously.

This is one of the oldest and most reliable means of asynchronous communication. 

Using email in conjunction with a text message or an attached video works even better. Try to be contextual and respect the other person's time.
