Your next step is creating the actual videos. There is no universal model for what works and what doesn’t work on YouTube. Some of the most popular content include professionally produced music videos and impromptu family videos recorded with a smart phone. If you want to record with a phone, you likely already have your camera in your pocket. Recording in HD will produce a better quality video, so be sure to use the highest quality possible on your phone. If you want an even more professional video, you can use a DSLR camera and external microphone.
Once you finish recording, you can edit your video with a desktop program like the free Windows Movie Maker or iMovie. which come with new computers, or a paid program like Adobe Premiere for more robust features. YouTube also has a free editor with basic features. As you edit your video, be sure you don’t use copyrighted music. If you do, your videos won’t be eligible for YouTube advertising.
