OBS is a popular software used to record Minecraft gameplay and we'll walk you through how to set it up. If you would prefer a more simple screen recording software, check out the alternatives we recommend.
Download OBS for free and then open OBS along with two browser windows. In the first browser window, log into your Minecraft account. In the second browser window, log into your DIY account where you will post your finished video.
1. Open a new browser window and sign into your account at diy.org.
2. In OBS, find the Sources box in the lower left corner and click "+". Select Window Capture and click OK.
3. As you select from the Window list, select your Minecraft window.
