Joseph Labrecque gives a presentation on designing effective video content for online consumption. He recommends keeping videos short between 2-8 minutes and focusing on quality of both content and media. Proper preparation is key, including outlining segments, writing introductions and outros, and keeping the rest unscripted. Quality audio and video recording and editing are essential, along with proper processing of audio to clean it up. Patching together content from multiple recordings is also discussed.
