Asynchronous (recorded) video is an ideal companion to live video. In fact, recorded video can often lead to live video interactions. For instance, in the sales context, by leaving a video message, you’re introducing yourself, building trust, and starting a relationship with your customer. By recording and leaving a video message, you’re more likely to generate a response that leads to a live conversation on video or otherwise.
Similarly in the recruitment context, by recording and submitting a video, a candidate can make a real impression on potential employers. That video could then lead to a live video session (e.g. via Skype) or possibly an in-person interview.
Asynchronous video is not meant to replace live video interaction. Think of it as a pipeline to live conversations.
