Học Open Broadcaster Software - Khóa học Livestream với OBS

We want to take you from zero to 60 with your OBS knowledge as fast as possible and a complete course update is the best way to get you going! This course will feature OBS 22 and review all the new bells and whistles, plus we will take the time to review how you can build the graphical assets you will need to create a stunning live streaming presentation. Unlike most of the other OBS courses available today this course is designed for live video production NOT video gaming. So it’s perfect for churches, businesses, and educators looking to make dynamic video presentations online.

We will start with an interface overview followed by a 15 minute zero to sixty presentation where we will go from this to this. We will show you all the essential shortcuts inside OBS helping you create an informational ticker, integrate your live chat room, build a split screen scene and make a picture in picture presentations that look amazing. Once you are up and running with OBS we are going to talk about the most important issue almost every OBS user has. We will learn how to properly sync up our video and audio sources using a brand new tool I have designed that is accurate to a hundredth of a second.

After hosting my OBS course on UDEMY for over 3 years, I have decided to rethink the course layout. Once we have covered all the basics, I am going to create short tutorial videos that you can choose to checkout al-la-carte. In this way, you can peruse through the available tutorials and choose the instructions that best suite your project.
