Training videos are a useful tool for teaching employees, customers, or partners new skills, processes, or procedures. They can improve performance, productivity, and compliance, but if not effective, engaging, or accessible they can also frustrate, overwhelm, or disengage your learners. Common mistakes include using too much text, slides, or graphics that clutter the screen and distract from the main points; delivering too much information too fast or inconsistently; failing to provide clear instructions, objectives, or feedback; and using a boring, formal, or impersonal tone or style. To avoid these mistakes you should use minimal and relevant text, slides, or graphics that support and enhance the main points; break down the information into manageable chunks with a logical sequence and repeating key messages; provide clear and specific instructions, objectives, and feedback that guide and encourage learners; and use a conversational, casual, and personal tone or style that makes learners feel connected and supported.
