There are a lot of fantastic points in this article. Video is absolutely the way to go because of just how engaging it is with customers. But when dealing with mobile there are a couple things that you need to make sure you are doing. You need to capture their attention early since attention span on mobile (especially on apps like Facebook) is pretty low. Design the video for sound-off viewing with things like subtitles. Have a clear call to action at the end of your video. The last thing is to plan for vertical viewing since “people are 67% more likely to watch the full length of square videos than they are to watch horizontal ones.” (source: https://sundaysky.com/blog/5-mobile-video-best-practices/ )
Make sure you know what you want your video’s call to action to be. You can include your homepage URL, a “Click Here” button, a thumbnail of another video, social icons, or almost any other form of CTA. These are technically graphic elements, but require a little more thought since you’ll want to consider what your video goals are and how you want the viewer to accomplish them. Think about their user experience and how you can present your CTA in the least disruptive way possible.
Video experts often credit 24fps with a more “cinematic” look, while 30fps is more common, especially for videos that need to be projected or broadcasted. A good rule of thumb is to ask the end user of your video what his or her preferences are and shoot based on that. Then, be sure your resolution is at least 1920 x 1080 to maintain quality footage.
