The fact that StoryPrompt is a video-to-video platform can really help with this common problem. The respondent will watch a video of you and then reply to you in the same manner. So if you are natural and not overly polished, they will naturally mimic that. The exchange then becomes a comfortable and relaxed one with authentic user-generated content being created.
Also be sure to tell your clients that you’re not expecting perfection. The most authentic and trustworthy videos are in fact that imperfect ones.
You can reassure them by letting them know that they can retake the video if they need to and also they can use a script which works as a teleprompter.
