Maybe we remember a few good ideas from the content we consume. But soon after time passes and we forget most of this information. It’s frustrating to spend all that time trying to learn something just to forget it. I want to share one simple idea in this post that is going to change the way your learn something. http://www.tysonmaly.com/video/how-to-shoot-video-for-faster-playback/ Fri, 03 May 2019 09:30:15 -0400 http://www.tysonmaly.com/video/how-to-shoot-video-for-faster-playback/ 5 Tips to shoot video so people can watch it at a faster playback speed and understand it I was pressed for time the other day, and I needed to learn something quickly from a 15 minute YouTube video.
