There are a few things you need to do in order to make a video landscape on TikTok.
First, you need to open the app and log in. Once you're logged in, tap on the + sign at the bottom of the screen to create a new video. To make your video landscape, tap on the settings icon in the top right-hand corner of the screen and select aspect ratio. Then, choose 16:9 from the list of options.
Now that your video is set up to be landscape, it's time to start filming! Make sure you film horizontal so that your video doesn't get cut off when people watch it. When you're done filming, add any effects or filters that you want and then post your finished product!
