You can't make Facebook video ads without videos. Like other social media marketing campaigns, you don't just create any video for your Facebook ad. It has to appeal and be valuable to your targets.
Facebook is like a wide space with a lot of content. It's easy for your viewers to get distracted. So, you should create a Facebook video ad that captures your audience's attention before they scroll past your ad on their feed.
Sometimes, you can make a great video with only a phone camera and editor. Though the process is not so easy, especially if you don't have editing skills, it is one of the less expensive ways to make a video ad manually.
Alternatively, you can use a camera and a computer to create your video. We'll discuss more about creating the actual video for your ads later. For now, let's assume you already have your video and you're ready to create an ad in Facebook Business Manager.
